Customer Reviews

Having mobile WiFi in Japan as a tourist is a must. When I arrived in Japan I managed to use Haneda's WiFi to plan out my station trip to Ueno where I would be staying. My WiFi device had already been delivered to the hotel the prior night and all I had to do was to pick it up, set it up (takes 2 minutes) and I had internet access for my entirety of my Vacation. Amazing little device with a very good battery life (upwards of 15 hours). At the end of my 3 week vacation I just dropped it off in the Haneda Airport post box before doing my flight check-in.

I received the portable wifi with a flat battery. The battery continued to cause me issues the whole two weeks of my trip, so I had to take my powerbank with me everywhere. On the last few days the device did not charge at all which caused a lot of problems for me.

The pocket Wi-Fi was great. The rental and return was easy, it worked great all across Japan. On 2 or 3 days the unit ran out of power during the day in spit of being fully charged, but otherwise worked great,l.

Handy, small enough to carry around and not heavy device, working well, the service was great, I have found no limitations.

It was easy to use and the instructions in English were very clear. It was easy to pick up and easy to drop off. I especially appreciate that there was a warning on the instructions that you could not get to a post office after going through security. It helped prevent me from not being able to drop off the wifi box. I would use this rental service again. The wifi also had enough charge to last potentially 10-12 hours of continuous use.

Very good service, easy to collect, easy to use and easy to send back. Overall great experience

A very fast and effective service from cdJapan. Feedback from the company regarding the rental of the wi Fi router was concise and all deliver and return logged. Download speeds were excellent all over the areas I travelled. All up an exceptional experience.

I have used it for over a couple month, worked excellently, even on Mt. Fuji which was surprising. Customer support reply was quick and helpful always. 10/10

Great service, communication and delivery. I have used CD Japan each time I visit Japan and will continue to do so.

Good service and convenience.

Maybe due to my location, no 5G network can be found, but even 4G, the speed seems relatively slow.

Having the wifi we rented from you was so essential and really helped make our stay in Japan so much easier and enjoyable. We highly recommend it for all people visiting.

網路穩定,30日租借方案充裕好用.可寄送到日本指定地址,還機只要投遞郵筒,非常方便。

Although I have used this service several times previously, the unit sent this time had poor performance. Many times it would disconnect the clients for no reason. At least 2 times per day it would overheat, and once it claimed the SIM card was invalid (shutdown, reinsert SIM and restart resolved the issue). Please check this unit to see if it is operating normally.

I found myself very well. pocket wifi working fast and with many gigs at a very affordable price

The device is a bit old which heats up quickly, and the device connection plug is a bit loose. But, no issue with power charging and functionality.
The device is delivered early.
This is actually my third time using this service but my first time having the 200GB device.

It was very convenient to pick up and return the device. We have travelled to over 20 prefectures in Japan and there was no connection issue anywhere.

Very useful, delivered on time and at a very competitive price. Not the latest hardware but totally functional and reliable. Great service, thank you.

Device was not useful and internet servecies disrupted time and again, i was displeased to use the device and was stuck due non functional device. Regret yr device was of not much use. Grateful pls refund the charges fully

Service corresponding to my needs: fast internet, no data transfer. Everything as informed on webpage.

Very Good Service.. Very Good Coverage.. There was some problem with one of the device and the same was promptly replaced at our destination

The device worked during our 24 days of Japan vacation more or less all right, but there were few issues bugging the experience a bit:
- the battery is good, but still sometimes it is not enough for a day trip,
- I noticed several times it switched off without my intervention,
- access to the Internet sometimes was of very low quality (speed, general feeling), and it seemed to be pretty random (not necessarily dependant on the location).
There are no logs accessible on it, the "display" is just a few LEDs, web interface is limited only to the usage display, so no possibility to diagnose what caused the above.

預約方便，也能提早送到飯店。
此外因為對日本不熟所以輸入的飯店地址錯誤，但CDJapanRental會協助找到正確的飯店地址很貼心。
但目前開放的機場借還服務還是太少，如果能在機場借還會更加方便。
最後也希望能增加Wi-Fi 分享機的選項。

Reliable and easy-to-use wifi rental service! I had my wifi device delivered to my hotel. It arrived on time and was ready for me by the time I checked in. I had no issues during my entire stay. The wifi device was light and the battery lasted a long time. Returning the device was easy as well since all I had to do was insert the device in the mailbox before leaving Japan. Thank you again, CDJapan!

Ordering the wifi hotspot through CDJapan was just as easy as it was the first time I used the service pre-pandemic, and the device worked pretty much without any flaws. I'm thankful for having this easy to access service because it makes exploring Japan during vacation a lot easier and stress free being able to access the internet for maps, directions, random translation help, etc.

The device was performing very efficiently and the ordering process was quick as well as the communication from CD Japan. I am very satisfied with the rental service and speed.

Wifi routed had great connection with no problems at all! I went to sapporo/sendai/tokyo and none of the places had any issues. I was also having work meeting on one of the days on zoom for 3hours and it was very smooth with no hiccups. Only on first day when I first used it at narita it didn't really connect good idk why but when I returned on last day back at natita it was good again! The battery was great too it could last me the whole day, even on one day I was out for 12hours I did charge it at around 10h mark with around ~30% just to be safe but I'm sure it could have lasted till I get back to hotel too! Highly recommend!

Wi-Fi was waiting at our hotel in Tokyo. It provided excellent signal with unlimited data for a month of travel throughout Japan. Only in tight canyons in Shikoku did we lose coverage briefly while navigating.
We would recommend this service to anyone who uses data traveling in Japan. We will 100% use this service again when we return to Japan in the future.

Have used this service many times over the years and have found the company to be very reliable, a competitve price, easy to set up and use. Also very good communication, responsive to queries and notifications.
Thanks

The portable wifi package was waiting for me at my hotel at Haneda Airport when I arrived, fully charged and ready for use. Since I was travelling to a number of more remote places and places I'd not been before, I aimed for the maximum coverage rather than maximum speed. The speed provided was still more than enough to watch 1080p video on my devices.
