Thanks to this sim card I travel around Japan without problem! Super efficient delivered before my arrival at the hotel. Arrigatoo!!

Very good experience & simply to use

Always had great WiFi and the portable charger came in handy so many times!

We decided on a last-minute trip to Tokyo for 5 days. After confirming our iPhones were unlocked, I researched eSim for Japan - there are plenty of excellent reviews on YouTube. Japan Wireless seemed the easiest and cheapest while still delivering excellent service. We stayed in the greater Tokyo metropolitan area and had excellent cellular data throughout our trip. My main usage was with Google Maps for the trains, and it was invaluable especially after changing plans on the go. The other main usages were GO app for taxis and Google Translator (especially the camera feature) during shopping etc as well as a currency exchange calculator app. Be sure to bring a portable charger too! If you don't have one, you can get fairly cheap ones in Tokyo especially if Akihabara is one of your destinations. However, if you plan to use it during the trip, you cannot claim tax-free. Last but not least, for the 3 of us during our short trip, I decided to get 3 eSims rather than a mobile hotspot so that we didn't need to remain tethered to each other.

easy pick up, unlimited wifi

Worked just as expected

The wireless router worked well for me and my wife sharing a connection though it did require a battery boost before the end of the day. We arrived in Sapporo which required us to go to a delivery service booth in the Domestic side of the airport and pick up our router there. It was hard to find but we did find it and get the package from Japan Wireless. Return is easy from anywhere in Japan via postal service box. Pickup of the device is likely to be much easier in Tokyo.

We rented one for a little over two weeks. Never had an issue. Pickup was easy and return was super easy. Instructions provided was simple to understand. I would highly recommend this

Everything worked really good even though our wifi had to endure the Tokyo summer heat :D

very good product and easy to use. Good connection and battery.
