レビュー

After careful consideration, I opted for a pocket Wi-Fi device instead of an eSIM. However, I recommend the eSIM option.The pocket Wi-Fi device offered acceptable battery life, requiring daily charging and not consistently lasting a full 12 hours. While the complimentary battery pack was beneficial, charging both the pack and the device simultaneously proved challenging with the provided low-speed adapter. Network connectivity was consistently reliable throughout Tokyo, Kyoto, Osaka, and Nara. I recommend pocket wifi option provided you have a high-speed adapter and cable. Esim will give you more peace of mind.

This was unbelievable during our 3 week trip, battery life lasted all day with 2 phones, quick to charge and fast internet.
Cannot recommend enough!

The wireless package arrived at my hotel exactly as mentioned and it worked perfectly on our trip in Japan. I also had no problem mailing it back in the enclosed envelope at the airport.
Whenever, I return to Japan, I will make sure I rent from your company again.
Thank you for such wonderful service.

Pick up and drop off were easy. Everything worked. Will definitely use for future visits to Japan.

Quick delivery, worked all day every day throughout Japan, and convenient return at the end of the trip.

The first day I picked up the device, I found that the device would not charge. I communicated through email and thankfully, my hotel had free wifi. They had a few suggestions but when they did not work, they wasted no time and had a new one sent to my hotel within 12 hours!
The device itself worked almost everywhere, just a couple of odd areas but no where did I feel like I had to search very far. It was like I noticed I didn't have signal but by the time I was at the other end of the shopping street, it was fine.

Easy set up and strong connection & speed even outside Tokyo.
Just had some issues in locations where there seems to be interferences/blocks, like deep below subways but overall I got way better experience with this service than getting the mobile router of SoftBank (terrible connection/service even in Tokyo).

I've been going to Japan for the longest time and I only use Japan-Wireless for my pocket Wi-Fi needs. Better than SIM card since multiple people can use it. Price is reasonable, there is always coverage, and very convenient to get and return.

Seamless process, always worked, great speed and no issues for a three week trip across Japan. Great service.

Was well worth getting this. Coverage was mostly excellent. I recommend this and will definitely use Japan- wireless when I return to Japan
