Customer Reviews

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

Ordered Item(s):

Fantastic service, zero issues. Highly recommended.

Ordered Item(s):

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.

Ordered Item(s):

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

Ordered Item(s):

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.

Ordered Item(s):

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.

Ordered Item(s):

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!

Ordered Item(s):

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.

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!

Ordered Item(s):

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

Ordered Item(s):

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.

Ordered Item(s):

Super easy to ordee, pick up and use!

Ordered Item(s):

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.

Ordered Item(s):

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.

Cell service was perfect I never had a problem with it. Directions were clear and understandable on how to use the SIM card and how to activate for a first time user. Would recommend

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

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.

Ordered Item(s):

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

Ordered Item(s):

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.

Ordered Item(s):

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

Ordered Item(s):

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.

Ordered Item(s):

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.

Ordered Item(s):

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.

Ordered Item(s):

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.

Ordered Item(s):

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.

Ordered Item(s):

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.

Ordered Item(s):

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.
