This is a service i can recommend, the premium wifi is a great way to explore Japan. When you have questions their customer service is there for you.

We a family of 4 adults needed a wifi all through the travel within Japan and the Pocket Wifi from Japan wireless was excellent. The customer service response for all queries were prompt and the instructions were good.

Pickup and Airport drop off was very convenient. It ensured I had internet access as soon as I landed until I was departing.
The internet access is also very fast and reliable. I have been using Japan Wireless for almost 5 years now and the service has been great.

Very easy and reliable overall service, nicely working wifi-box with easy setup, highly recommend!

The best choice to have wifi in Japan.

basic but reliable, and always working even in the most remote places

Easy to connect. Good battery life. Same day pick up. Simple return. Would use again.

Easy pickup and dropoff. Great functionality and unlimited data.

I picked up this product at KIX in late May, and, for almost three weeks, it worked fairly well. The only complaint is the difficulty of finding the place at KIX.

Love that we can use the discount coupon upon ordering! Great to have our Wi-fi at our hotel upon our arrival. Easy return process. Sometimes Wi-fi goes down quickly but guess it depends on our usage. The tips you folks send are helpful! Thank you!
