What is a portable Wifi Router

A mobile WiFi router allows you to access the Internet on your smartphone, tablet, and other devices by connecting to the local mobile network. This lets you use the Internet abroad without facing high roaming charges.

Renting a Pocket WiFi Router In Japan

Renting a pocket WiFi router in Japan is straightforward. You simply fill out an online application (all providers have English booking pages), and the router will be ready for collection at the airport upon your arrival or delivered to your accommodation shortly after you arrive. Both options are often free; if not, expect a small fee between ¥500 and ¥1,100. Booking your WiFi router two to three days in advance is usually sufficient.

Once you have the pocket WiFi router, just switch it on, connect your devices using the provided password, and you’re online. Before you leave Japan, return the router in the prepaid envelope by dropping it in a postbox or leave it at the airport before checking in. Different providers have different return instructions.
