I got a Japan wireless e-sim for a 14 day ski trip through Tohoku (Iwate, Akita etc) and a few days in Tokyo either side. The setup was a little tricky but I got it up and running in around 30 minutes. The cost is a bit more than a portable wifi but there was no reservation, pick up, drop off or separate device to charge. I found this extremely convenient. The coverage was good even in the more remote ski area's and very good in the city. Would recommend.

Having previously used portable WiFi devices I decided to try this option instead for this visit. I personally found it easier than having to carry two devices and would happily do the same in the future.

A great service! Smooth and efficient and device easy to use. First device was faulty so these guys sent us a replacement wifi and all was good. Highly recommend!!

I will definitely get this again on my next holiday in Japan. Super convenient and easy to use.

I ordered the esim outside Japan and it worked instantly when I turned on my mobile in Haneda. Highly recommended much better than a dongle.

Japan esim is highly recommended, the customer support reply to inquiry as soon as possible and internet is very reliable all throughout the time.

I got the 30 day plan but I was only there 12 but for the money it was worth it I felt like I was fine with data !!

Japan Wireless eSim service is a reasonably priced solution to roaming in Japan. Their easy sign up was fast and near instantaneous to implement. Once you arrive in Japan, just scan the supplied QR code at home (print it prior to arriving) and boom! You are in the network. I didn't have to think about it again during our trip. Our iPhones worked normally. One thing to improve--we could only use the one cellular network at a time. Not both. My previous experience with a physical and eSim allowed me to use both my home country and JP networks at the same time. Now with two eSims installed, I was only allowed to use on network at a time.

Downloading the e sim on your phone instead of getting a pocket wifi. Makes travelling much bette.

I've been through remote areas in Kyushu and signal is good
