I recently rented a mobile WiFi hotspot (also called a “pocket WiFi”) from this store. I used it in my recent travels to Japan, and got internet service everywhere I went. My friends and I rented a van and drove from Tokyo to Kobe, Osaka, and Kyoto. I was impressed as I had reception and internet access everywhere. This included while driving in the boonies, on small mountain roads, back roads, and even when I visited some of Japan’s famous racetracks which are often located in the middle of the countryside.
