I enjoyed using CDJapan's pocket wifi. It worked very well, on the train, where I was staying, etc. It was so useful and effective that I kept on extending my use of it, until I didn't need It any longer. The discount when I extended it was also a great incentive to extend my use of the pocket wifi.

It was great service.

客服人員回應迅速並能作出有效的建議,對於客人的意見也很有耐心的解答並持續幫助,本人十分滿意。 只是個人認為CloudAir的網路速度即使在流量沒超過的情況下仍沒有到令人滿意的速度 對比Softbank Highspeed後,CloudAir變得可有可無。

Cloud Air Pocket Wifi

Quality and easy to use WiFi Rental service. Pick up and return at airport post office. Even if you didn't know Japanese, just saying "WiFi" or something similar, the staff will probably understand it. Had unlimited data plan with good speed and good battery life.

Very good. No problem.

It was far better than SoftBank Air in terms of connectivity, still there were time of delay in downloading.

Cloud Air has poor performance. Service was responsive

Excellent service! I had no problems.

Good pricing and I very much appreciated how fast the support responded to my questions and helped me. Very good service.

Dongle worked well, price was very reasonable. The only places I couldn’t get reception were long tunnels while on the Shinkansen, which makes sense.

For our 15-day trip, we rented two CloudAir (150-GB cap) pocket wifi units. The most difficult part was choosing the right pocket wifi. Ultimately, the price points were reasonable to get these nearly unlimited devices which served our group of 6. It was very convenient to pick up in the Narita airport post office. Each device came with a little mesh bag, USB charger and cable as well as a pre-paid return envelope. The return was very painless. The instructions in English were easy to follow. I packed everything in the mailing envelope and deposited it in a mail box at Haneda International terminal. I received confirmation a few days later of receipt of all of the equipment. It was very painless!

Great service, I’ve used it on 6 trips to Japan. The customer service is flawless and flexible (my mistake on dates, not theirs) with prompt replies to email when you need it. Simply outstanding.

I had access to wifi during my trip, so I wasn't using my data very heavily, but having 200MB/day was perfect for me and I didn't notice any throttling or speeds slowing down. I was using my dual-SIM phone (with an Australian SIM, texts & calls only, no data) and I didn't have any issues!

Device used:
Motorola Moto g7 power XT1955-4

Pickup and dropoff were very easy, and I liked the flexibility because I was arriving and departing from different airports. Between two users, the speeds were excellent. The battery life of the unit was perfect for an entire day's use.

Perfectly organized, everything very smooth & comfortable. Great service solution for travellers.

Great service as always! Items were waiting at the hotel when we arrived, worked great and were easy to ship back.

I chose the Softbank unlimited. Package waiting for me at Narita PO. Worked perfectly on a W7 netbook and a Moto G7 smartphone. 100% reliable for my entire stay. Very fast connection and retained charge for a long time. Pocket-sized. Handed in to Narita PO at the end of my stay. Absolutely brilliant.

Great item again. worked perfect all over Tokyo

Whenever we asked questions we received response quickly. Very satisfied.

Easy to use and instructions are straight forward. Quick email reply too

Everything was perfect. The router was waiting when I arrived, fully charged and ready to go.

Quick response with a friendly support upon arrival due to a size mismatch on the SIM and perhaps the best service I have used in all my visits to Japan! All information to enable the SIM cards was clearly explained.

Customer service was outstanding and did reply very fast.

Really easy to use. Picked up at airport post office. Battery lasted the whole day and usually still on 50% by bedtime. Dropped off at same post-office. Very happy and definitely worth having

Always reliable. I’ve used this service > 3 times and it’s always easy to use, works exactly as expected and really helps with navigating in Japan.

The CDJapan pocket wifi service is excellent and as usual it was super efficient and good value for money.

Great to have access!

Package is easy to collect and easy to return. Clear instruction on the usage of the device. Price is reasonable. High speed and good connection most of the time.

Excellent service and easy set up, good information available. No issues.

Everything was clear and easy to manage.

Have used for a number of years. Excellent service & competitively priced.

It was great! I am very happy that I decided to rent that Mobile Wi-Fi gadget. It saved me a lot of trouble in Japan. I was absolutely free to move around, looking at the maps, searching for train schedules and local sights, chatting with friends, sharing photos, reading mail, and watching YouTube! My Russian mobile plan would not allow me to do it, it would probably run to the limit in a few minutes.

The router was enough to spend our stay without trouble. Even after exceeding the day limit, the reduced speed was enough to use maps. It's very easy to get and give back the router.

Great at usual. Reception is good almost anywhere, the package is always neat and easy to use.

Device used:
Samsung Galaxy S10+

Great speeds and long battery life! The process of purchasing the services was quick and easy. Picking up the package from the airport was also super convenient! My only suggestion would be to send the device/service notifications in different languages. I had about 22 notifications that I couldn’t read, because they were mostly in kanji.

Very good service. Was easy to use and manage. Will use this service again

Great and easy to use, the device was delivered to my hotel perfectly on time, and was easy to return at the airport. Internet speed was fast, and had plenty to spare at the end of the trip. Would definitely use again next time I'm in Japan.

Excellent as always... I only rely on your service whenever I am in Japan.

I enjoy using your rental service. The devices are easy to use.

Thank you very much for your service!

Luckily I stopped in Tokyo Disneyland first fo a couple of days so I was able to have it sent directly to the hotel and I received my sim card as I checked in. My final destination was Okinawa and they dont seem to deliver there yet. But overall Excellent service and sim work flawlessly though out Japan to include Okinawa. I will definitely rent again.

Internet was fast, pocket wifi was easy to use, and instructions were very clear. It arrived on time to our hotel.

I always love renting from CDJAPAN for SIM cards. The set up is easy, pick up and drop off is also very easy. But the only thing I had a difficulty this time was I rented 2 different kinds of SIM cards and I was not really sure which one was which. I wish they would label or write a message to the customers.

Intermittent internet service, however transaction was otherwise smooth

This rental service is top notch. The equipment I received was very high quality and never failed me. It is very easy to use and comes with effortless instructions. A life saver and must have for your trip to the beautiful country of Japan. I will used CDJapan every time I visit, no need to look for any other WiFi rental provider. They will take care of all your needs.

Great service, sim card was delivered on time before my arrival in Japan. The envelope contains all of the required steps to use and activate the service. The sim served its purpose on my 2 week Japan trip with plenty of coverage which was great as I always needed to use Google Maps and check out restaurant reviews!

Great service as always. Picked up at Narita Airport post office, it was charged and worked as soon as you turned it on and put the credentials in your devices. Battery life was great, and the coverage likewise. Very little if any dropout the entire time, even in Shinkansen tunnels.

Great service as always. I made a couple of mistakes 1, ordering it to start the day after I ordered it (I actually wanted to start it about a week later - when I arrived in Japan) and I needed an extra day. Both were easily dealt with. And setting up on my iPhone11 was really easy!

The pocket wifi was good and the 350 MB / day was more than enough to stay online, use maps and apps while hiking etc. Next time maybe make sure the Bus Ticket is also in the envelope though ;) Was not a biggie, thank you for refunding the money so fast! I will use your service next time I visit Japan definitely :)

Very happy about the rental. Worked perfectly. Easy pick-up at the Airport.

Great service. Fast reliable. Highly recommend for a couple travelling together with multiple devices

Very happy! Rented the pocket wifi for casual users, 350 mb. We used it mainly for maps of areas we were travelling to and for sorting out buses and trains on how to get there. Found the 350 mb to be sufficient. It also worked everywhere we went - Tokyo, Fuji-san, Matsumoto, Tateyama, Kyoto, Osaka, Hiroshima - as well as on all trains. Highly recommended!

The service was seamless, when we arrived at the Hotel , the pocket WIFI's were there . The system used to return the units is also made easy , by placing the units in any Post Box any where in the country. The system WORKS.

This device was extremely useful to me in Japan, and I really couldn't have done without it.

great service, easy to use

Very good service, ave used this service before. Good customer relations

Very simple to use. Ordered via website. Picked up at Narita Airport. modem was already charged 100% and instructions were included. Very fast D/L speed and didn't lose connection even when traveling from Tokyo to Kyoto to Osaka. Did have some slow connectivity in the subway, but we were deep underground and it was to be expected. Modem range was very good well over 100ft. Battery life is excellent, stayed charged all day with heavy use (Google Maps, and Youtube video streaming). Return was simple using the included return enveloped and just dropped off in the postal box at KIX airport. 10/10 use this service again. Highly recommend.

Good Price and super easy to use. You can send it easyli to your hotel and when it’s finished bring ist to the next Post Box.

It was very easy to order, I was keept up to date on every status of my order by e-mail, the possibilities to pick it in the airport up or get it sent to my hotel was very conviniend, easy to return and easy to use. Worked perfectly - thank you.

Very, very good. I rented a mobile Wi-Fi router for two weeks in Tokyo and everything worked great. Even though there was an issue with my hotel booking and delivery, CD Japan informed me immediately and managed for me to get my device in time. Thank you so much for that! The device itself worked super well, internet was always very quick and available everywhere I went. Battery lasted all day, even if switched on all the time. It sometimes switched itself off though, which was a little bothering, but I think it was the (really) hot weather's fault. Return was as easy and convenient as described. Really great experience and I recommend it and also will use it again any time. Thank you very much!

Received items at hotel as expected, and using the wi-fi was easy. Only problem is that it sometimes doesn't work on the subway, but that's to be expected. Returning was easy at the JP Post Counter at the airport (and it allowed me to use the wi-fi to the fullest extent).

I have used this service before. Always very easy to pickup and return. Very clear and easy to follow instructions.

Third time I use the service in the last 3 years and everything worked as planned.

Device used:
Samsung 10 plus

Quality of the service was very good. Connections with router are smooth, all connected phones and PCs worked perfect. Also the coverage was proper both in the big cities as well as in the countryside. The only small issue is the router in the offer has battery not sufficient for full day of normal data usage (communicators, maps, sporadic Internet browsing with no video etc.). You just need to have a power bank handy if you spent most of the day sightseeing.

I’ve been using CDJ rental service for years now every time I go to Japan and it’s always been reliable and convenient.

A must-have every time I visit Japan! Highly recommend it! Before learning about this service, we would periodically go to a Net cafe to use the internet, which was inconvenient and pricey. The pocket WiFi is extremely convenient! You can get high-speed internet basically anywhere and it is small so easy to carry around. I usually have it sent to my family or friend so I can pick it up, but it is also very easy to get it delivered to the airport, hotel, or Airbnb. It comes with a self-addressed and posted envelope so it’s easy to drop it into a postbox to return as well. Even if you don’t have cellphone service in Japan, you can use an app like Facebook messenger to make calls or send messages. If you have an iPhone, you can also send texts/iMessages over the WiFi.

Great service! Thank you so much. The WIFI Pocket was delivered on time and made our holiday so easy and smooth, but the thing that we enjoyed the most was the super efficient and fast customer service, that would reply to our email queries within minutes and provided immediate support. We highly recommend using this service to everyone going to Japan.

Excellent service. I have used cdjapan twice, and I'll use it again next Time.

Very good service! It's essential to rent pocket wifi when visiting Japan so that getting lost is not a problem anymore! Battery should have longer life for the day but you can opt to switch the device on just when in need. Overall I'm satisfied :)

I picked up the pocket wifi upon arrival at post office (Narita Airport). Set-up was fast and easy.The pocket wifi was the perfect solution for me, it was reliable and worked anywhere. Returning it with the provided envelope was fast and simple. I'm a so-called "heavy user" which is why I chose CDJapan.

Device used:
Softbank unlimited pocket wifi 303ZT (I think)

Fast.Easy.convenient. Will rent again.

Ordered it a few weeks before we left Australia, delivered to the hotel as promised and waiting for me when I arrived in Japan, easy to set up and supported several devices with no problems, easy to return just drop it in a post box plus you get frequent reminders for when it is due back and confirmation when it has been received back by CD Japan.

CD Japan is consistently one of the most inexpensive services, plus it's unlimited data. Also, it's very convinient as it's delivered to where I'm staying before I get there, and at the end of my contract I just drop the prepaid envelope in the post box. Between that and the tons of free WiFi services popping up in Tokyo, I don't need a different service.

Device used:
Samsung Galaxy S9+ SM-G965U1

I chose CDJapan due to the flexible and convenient pick up and drop off location. I also chose CDJapan because of their quick response time and ongoing communication during troubleshooting times and their 7day mobile wifi plan which was perfect for me and my circumstances.

Worked seamlessly the entire time. Ran out of battery one day after heavy use.

Very nice service and good quality!!

Extremely good and when one of the devices I rented stopped working, there was prompt and quick customer service to help me immediately get another device out.

Staff was very accommodating and sent the device to my dorm room. Very easy to set up, charged fairly quickly, and battery life was good. I got signal everywhere I went, which was nice. Sometimes the device would turn itself off and pressing the power button wouldn't work so I'd have to plug it in to charge so it would come on, then it'd be fine (but it would be fully charged). That's my only complaint. Everything was nice and convenient.

Brilliant. Worked everywhere we went in Japan (urban and rural). Fast, convenient.

The CDJapan Rental was fantastic! I always had service, and I don't think I ever overused the data so the service was never slow. It was very reliable and easy to use. The instructions were clear, and returning the SIM card was also easy to do. Overall, it was great.

Excellent service. This is the third time I have used CDJapan for pocket wifi and each time its been seemless - very easy to use and a great product.

Easy to get, use and return. Sounds like it's not enough at first but it was great! + the communication was good too. Thank you!

iphone 8

Second time using the service. SIM card arrived at the hotel by the specified date, and had no issues getting the card to work in the phone using the provided instructions. Service coverage was generally acceptable. Daily data limit at max speed was surprisingly easy to hit even with just using Google Maps and navigation, as it's not possible to pre-download map data for Japan- after hitting this limit the data rate was rather slow and required standing around waiting for things to load. I would recommend disabling as many background services using data over non-wifi as possible. I prefer the convenience of the SIM card over the "pocket wifi" devices, although the pricing and speed options for the latter have become more compelling.

Service is prompt and accurate. Speed is pretty fast. Unable to use it on a cruise (during cruising) but signal resumed on all shores. Returning the package is very easy as the instruction is clear.

Very easy to use service. They had simple instructions to follow for installing the SIM and profile, and the return was as simple as giving the envelope to the hotel desk staff to post for me upon leaving. I've used CD Japan for several trips now, they're my "go to" service for a data plan while in Japan.

I've used this service twice, and each time been very satisfied with the ease of the whole process. I compared an overseas plan with my cell phone service provider, and found it more expensive for the access I wanted, and rented a portable WiFi from CD Japan. I had no issues or connectivity problems at all with this device, and as I was meeting with friends at a concert, I was happy to share my WiFi with them since the "free" service at the venue was bogged down. I have recommended CD Japan to overseas travelers before, and will continue to do so.

The full rental experience was very smooth. No line at the post office at the airport and very fast pick-up and deposit. We rented the no limit pocket wi-fi for 16 days and we never were out of line: place visited include Kanazawa, Kyoto, Hiroshima, Nara, Osaka, Miyajima and Hakone. I really appreciated the notification e-mail during the trip. As you may understand, internet is essential for non japanese speaking, and with CDJapan we could focus on the trip and enjoy Japan!

ze doen wat ze beloven en het werkt gewoon erg makkelijk. WifiBox was er op het afgesproken moment. Duidelijk instructie (incl. FAQ), retourenvelop aanwezig. Snelle verbinding en altijd bereik gehad. Totaal geen opmerkingen. Ik ben zeer tevreden.

Really useful gadget to have when travelling around japan. No problems with the wifi box. Always high speed internet and the pick up, renewal and drop off processes were simple. Recommend!

Quick, convenient, reasonably-priced and instructions are easy to understand. I have many overseas visitors and I only use CDJapan SIM cards and devices. Users must just make sure there is no theft protection or other form of SIM lock enabled on their device before they come!

Fantastic service. Easy to order, use, great range of coverage, great battery life, strong and stable wifi. I would recommend this to anyone travelling to Japan!

Good service. Device arrived as scheduled and with clear instructions on how to set up and use. Solid and stable wifi connection achieved, even in car. Convenient return service too. Perhaps a little costly, at just over JPY600 per day. That’s the only criticism I can think of.

the wifi device has some quirks and in my experience worked best in bluetooth mode. just having the wifi on would mean that in long periods without activity the router would sleep, and had to be manuall reactivated and re paired. I noticed a number of occasions where wifi connection wasn't actually working also. with Bluetooth pairing, the phone kept the wifi router on more reliably, and connected with less fuss, although the connection over wifi was much faster... but good over all and helped me get around Japan on my stay

Nice coverage and signal was very good at most places.

Received the response in a timely manner. Very good customer services.

The wifi device was delivered on time to our hotel only 2 days after having ordered it. Instructions were simple and clear, worked perfectly the whole trip.

Strong connection, however didn’t work while underground on the subway. Also sometimes had to hold the power button down for 20+ seconds to turn it on/off.

Loved the portable wifi. It was useful and provided a generous amount of data for me and my partner during our 2 week trip. Will definitely rent again.

It was a very efficient service and the internet option purchased worked successfully with a fast stvic and even worked on the subways in Tokyo and Kyoto which I guess is also down to Japan Infrastructure. Would definitely use again if come to Japan again and price was very reasonable for service offered.

Easy to pick up at airport. Easy to connect. But found battery would not last the day we were out, had to always recharge whilst out which added worry

Very satisfied with this service. It's the second time I've used it. Due to flight problems, I was not able to pick it up from the airport and they send it to my apartment, extending my period to compensate. And I had no problems extending my rental period. Very professional and prompt.

Fantastic. Delivered in time. Device worked perfectly and was very reliable in all locations in Japan (Tokyo, Nikko, Kyoto, Nara, Osaka).

Everything works very good and was well organised, but the battery didn’t last very long that said I did get the cheapest one.

It’s a great service. Don’t change anything!

Great service! Everything is super clear and easy to use! Also, the return of the devices is made very easy with the return envelope! Thank you & we will definitely use your services again.

I had a trip by Japan with my family. We was triping from Narita Airport to Kagoshima by train and was staing in several cities. 4 android phones were connected all the time. Battery of our Pocket wi-fi was providing about 10 hours continiously working! We had no problems with connection on all our path, coverage area is good! May be one or two times Internet was unavaliable for 3-5 minutes (but i think it was because of network, device was ok). To the end of trip used traffic was about 45 Gb :) and speed was always high! Thanks CDJapan - I recommend this service for using. Our trip was convinient with CDJapan. And at the end of the trip I just drop delivery package to the mail box at airport :) (it was free of charge because envelope to send was in CDJapan package).

Very good service and product

Simple to use. Pocket WiFi was waiting for us at the hotel and the free postage envelope is straightforward to send the WiFi back at the end of our holiday. This is my second time using this service and I will definitely use again on my next visit to Japan. WiFi was fast and we had plenty of data.

Very efficient service Pick up and return via post is seamless Speed and bandwidth of the wireless was outstanding No issues experienced

It is reliable and Not too expensive, but the speed is very slow. It is ok for navigating and messaging but you can’t watch videos or upload or download large files as it is too slow.

Very helpful, very easy to use.

Wouldn't travel without this. It was critical to navigating Tokyo and Kyoto, and made it much easier for us to find what we needed on the fly. Device functioned flawlessly. Battery life could have been an issue because I did express shipping so didn't get the backup battery, but did bring my own pocket charger. Device was at my hotel at check-in and simple to return.

convenient for foreigner who need to use WIFI service in Japan. I use in several part of Japan (from Ibaraki to Gifu and pass the other prefecture), it is a good response, long live battery.

Thank you again for another satisfactory rental!

It was very easy. I picked it up at the airport, turned it on, and I connected to the WIFI. It surely covered all the days I was in Japan. It saved me lots! I'm using this service again when I come back this March for the Sakura season. Thank you CD JAPAN!

Super easy - wifi was waiting for us at our hotel and we dropped it off at the airport. No hassle, and it was super handy for our trip around Japan.

Great service, device worked very well and served our needs perfectly.

The device was delivered to the hotel (in Osaka) on time as requested. Returning it by dropping off at a post box at Haneda Airport was easy. The device battery was good and most of the time, it could last for a day. Couple of time, we needed to use it with a power bank. Regarding the wifi performance, we didn't see any issue while using in Osaka. But, in Kyoto, we did see connection dropped in higher ground (like top floor of Kyoto Station) and Arashiyama area. In Toyko, several drops were experienced at subway.

Was very easy to pick-up. The first time around I used it, I didn't feel the internet was slow even after the 110MB limit a day (2016). However, this time there was a significant difference. I was prepared for it so it was OK. It is still good value for money, especially since most other providers do not allow you to extend past 2 weeks. It also worked on the Samsung Galaxy S6

This was my 12th time in Japan, and I have always been very happy with the mobile wifi I rented from CDJapan. I have tried a few other brands over the years and some of them have been very disappointing. CDJapan has always worked fast and reliable. The usage limits are clear and the speeds are as expected from 4G/LTE. I usually take their highest tier and it works flawlessly all day long, even for watching Netflix or other intensive usage. Highly recommend when going to Japan.

Easy to use simcard. Just need to insert and follow the instructions given in the packet. Do be careful of the daily limit. The speed slows down quite abit after limit is reached. Only thing to note is signal might not be very good if deep underground like in trains or basement of building.

I am very satisfied of having ordered this rental through you. The device arrived to my hotel on time and worked perfectly. It was very useful for me, specially to find directions and the connection was perfect everywhere. I really would recomend you to use this service!! Thank you very much and best regards.

I am very satisfied with your service and the performance of the wifi router i got. I just found it hard to explain in English to the Post Office staff what I was picking up from the Post Office. I told them I am expecting a package from cdjapan. They asked for a parcel number. I could not give them any. One staff, who could understand English finally was able to help me and just looked for a parcel with my name on it. And sender was not even cdjapan. I got my router evenrually.

The ease and cost of the service were very good. The instructions for use and return were also very good. Having this as an option provided us the ability to use google maps for navigation which was vital to our time in Japan.

This is my third time using CDJapan Rental sim card and I am really satisfied with it. Your service really helped me a lot as it is quite hard to find prepaid sim cards in Japan.

Second time using CDJapan's rental service. Everything works well as advertised. Wifi is blazing fast and coverage is great.

Device used:
Galaxy Note 5

Price was very reasonable, wifi box was easy to pickup and return on arrival/departure, signal worked great in all the cities I visited while in Japan.

The battery life of the router was great and connection was superb even in the 5th station at Mt. Fuji. I'm definitely going to use their services when I come back to Japan.

I found it very easy to pick up/drop off at airport (I didn't have it shipped to my hotel because I find Japanese addresses very confusing), It only lost coverage in remote areas while on a train (If you are only staying in a city you should be fine). I would highly recommend CDJapan's Wifi rental service.

I use their SIM every year myself but this time, I ordered a mobile router after a minor problem with a SIM. Quick solution was provided by them and the router worked well. Always helpful and flexible when there is an issue to be resolved. Good, reliable service which I would recommend to friends and fellow travellers.

This is my 4th time renting from CDJapan. Delivery was prompt. I picked it up at Narita T2 post office with no issues. Service was always reliable at a fair price. Items were well packaged with easy instructions. Customer service is top notch. CDJapan is my pocket wifi/SIM rental of choice whenever I travel to Japan.

Excellent. No problems.

Good service, worked fine for our time in Japan.

Excellent pocket wifi, exactly what we needed for our trip. Great customer service & communication. Would definitely use again in the future :)

Fantastic service, zero issues. Highly recommended.

The pickup and returning of the device from Post Office was very convenient. Network coverage was pretty good. Will be even better if CDJapan can consider providing DATA SIM card for those with their own pocket wifi device.

I thought the price was great and the service fantastic. Just too many reminder emails!

I am very happy with your service. It deliver the parcel on time & good communication with client. May be there should be a cheaper charge for low user. May be there should be a cheaper charge for low user.

Communication prior to the usage dates was prompt and answered all questions. Usage during the rental period was excellent and worked in all areas, even when I travelled to Togura, Nagano. Only thing that was a little worrying was returning the item as it was marked as overdue. Only when checking the shipping out of the device did I realize that it would take several days to return to CDJapan. Perhaps the best thing you could do is include the tracking number in the paperwork that the person keeps. That way they can track the package as it is returned to you. I regret not doing that myself.

I've used this service many times, both the sim card and pocket wifi. Each time I rent for at least 2 months, and it's always inexpensive and reliable. The ease of setup and return is a big part of why I keep coming back.

I am a 3rd time repeat user and will probably use it again. Overwhelming value, prompt service. Works everywhere even on top of mt Fuji!

As a foreign tourist in Japan, I found the Mobile WIFI Standard Speed 10 days Rental very useful. The price is good and the service is excellent.

Mobile WIFI FS020W

Great coverage! Never switched the device off and it worked perfectly. Fantastic with Google maps..no more fear of getting lost in Japan ;) thank you for the great service!

The Softbank Wifi dongle worked well everywhere I used it, in big and small towns in Shikoku & Honshu, from Kotohira to Mito.

Good service, easy to use. Sadly the wifi didn't have connection outside of city areas, so I would not recommend this if you're in a village / nature often.

Super easy to ordee, pick up and use!

I've been a long time user of your service, the only problem I always encounter is there's always no service at the basement/underground of Tokyo Station, to be specific, on GranRoof restaurants. Not sure if it is really a deadspot since I've tried both pocket wifi and simcard and nothing worked. But anyway, elsewhere has good signal and I can't complaint.

I have used this service many times and I find it to be the cheapest and fastest option in Japan. The device is easy to get because it's mailed to you and it's easy to return because you mail it back before you leave. I will definitely use this service again on future trips to Japan.

Great service. Easy directions for both collection and return of item. Only thing was the speed of the internet connection was a little lagging.

I guess the only feasible and cost effective scheme for any non japanese tourist

It was my first time in Japan and I wanted to be connected all the time, and CD Japan didn´t dissapointed me giving excellent connectivity all around Japan 24 hs a day- If I would travel to Japan again, I will choose CD Japan for sure, and in fact I think to recommend it to someone who travels to Japan. Ther fullfilled all my expectations on their service and more. Thank you very much.!

Great service. Worked well everywhere - even in urban areas and mountains. The data limit was more than sufficient. Overall was a really pleasant experience. Really a life saver in Japan.

The pick up and return method was excellent. I was using the white wimax portable wifi router, but the signal was quite bad. I don't know why but even in the middle of Tokyo the signal would lost everytime I entered some of the buildings. I was a bit disappointed. However, the speed was great when the internet was available. Overall, it was good. Thank you! :D

The service was great. My pocket WiFi was available for me when I arrived at my hotel. I needed an extra day, and that process was simple as wel. I’ll use CDJapan Rental next time I go to Japan.

The rental service was very good and convenient. We even did not spent all the megabytes. And the signal was good during all the travel. Battery is enough if you realize of turning off during shinkansen travels and in some large places while visiting.

Outstanding service, I would highly recommend. Thank you

Excellent service. Cheaper than most other operators and a range of products. Excellent communication along the whole rental period. Wouldn't hesitate to use this service again.

Great, timely service, SIM cards were there at Narita as expected. Had no trouble with either the coverage or the speed of the connection. We were using European model Galaxy S9 Duo-Sim (Exynos chip, not Qualcomm) and had no trouble running both our European SIM cards and the CDJapan SIM cards at the same time. Returning the SIMs was hassle free with the provided return envelope. Thanks from Finland! :)

Very good service. I received the pocket WiFi to Narita airport and was able to pick it up right after I landed. It worked during my stay in Japan without any problems, and lasted the whole day. Returning was also very easy. I would highly recommend.

I rented one of the light data user wifi boxes. The speed of the wifi box was good, though sometimes it would take a long time to connect to my phone, despite there being good signal. But, if the box was turned off and then on again, or left for a few minutes, it would eventually connect. It was really easy to extend the rental period, and easy to return as well. Would definitely recommend, though do keep in mind there may occasionally be connection issues.

Great service and worked as advertised.

Second time using the service and very happy. It’s easy to set up and works pretty much everywhere. The price is extremely reasonable and I would recommend it for anyone planning on travelling to Japan. Especially if you want to move around a lot and need to look up directions or train times - it’s so easy

I found the device extremely useful during my stay in Japan. I was able to use LINE and Google maps thanks to the pocket wifi router.

WiFi worked really well with coverage and good speed everywhere (we spent most of the time in Hokkaido). We collected from the airport post office (Osaka) with no problems and returned via the prepaid envelope again without any issues. We got the 3 week deal and used it pretty much every day for google maps navigation in the car and a bit of surfing . Data included was plenty Happy to recommend.

Portable WIFI worked great, never had an issue during my 8 day stay in Japan. I would normally have 3 devices connected at one time (phone, IPAD and laptop) and no connectivity issues at all. !

I was very happy with my pocket Wifi rental. It was waiting for me at my hotel when I checked in and drop off was easy at Haneda International in the red postal mailbox on the departure level. The service worked very well for me and I was pleased with everything.

Pocket wifi worked as advertised - the nice difference for CD Japan was upon return - receiving and email letting me know they received everything back and that we're square. Overall - a pleasant/positive experience.

Great rental service! I’ve used CDJapan for pocket WiFi service last year for 90 days living in the outskirts of Tokyo and this time for 14 days for a vacation throughout all of Japan. Both times, I had no issues with their products. They provide clear instructions on how to use and how to return. They are fairly priced and have different options for data depending on your personal usage. I would recommend to everyone! Thank you CDJapan for making my Japan trips more simple with easy access to WiFi.

This is the third time that I have used this service. Very efficient. I am always happy.

Great product, high speed and I was able to connect easily everywhere I went, including Hakone, Kanazawa, Nagoya, Hiroshima, and, of course, Tokyo. The process is super simple and convenient. The price is very reasonable.

All worked seamlessly. Booked about 2 weeks before our trip. Picked up pocket WiFi at airport post office as planned. No problems using it for 3 of us all holiday. Put in bag and posted in local post office at 11.30pm of final day. Perfect! Really efficient and great value for money. Thanks!

Easy enough to rent online, pickup at the Airport and send back. The Wi-Fi hotspot worked fine through Japan with good speed. Very worth while to have internet for your devices.
