Customer Reviews

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!

Excellent value for money.
No blind spots even in remote areas!

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.

The rental wifi unit form CDJapan was perfect. It provided fast and reliable wifi unit, was easy to carry and charge, and there were straightforward ordering and return processes. Most importantly, the rental was at a reasonable price. Very pleased with the overall experience!

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

I first used CDJapan rental service back in 2016. Since then it has become my go to shop for SIM Cards or Pocket WiFi rental during my holidays in Japan. Good service, competitive price and very easy to use and return. Already recommended to my friends visiting Japan!

Pick up and return methods are just fine.
An app for android setting would be perfect.

The service worked great! I've used it for two trips to Japan now, and I plan to use it on my future trips, as well.

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.

I have used CD Japan service several times and have always been satisfied with the service

Great service and coverage as usual! This is my fourth time to use CDJapan, and it's never failed me!

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.
