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).

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.

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.

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.

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.

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.

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!
