Connectivity
A pocket WiFi router is still the simplest way to get several people online in Japan, and it works well on the shinkansen where onboard WiFi can be patchy. Here is what it costs, how pickup works and when an eSIM is the better call.
Typical rentals land between 400 and 900 yen per day depending on the data allowance and the router model. Unlimited plans usually include a fair use throttle after a few gigabytes a day. Insurance for loss or damage is normally a small daily add-on and worth taking.
Shinkansen cars offer free onboard WiFi, but it slows down when the train is full and drops in tunnels. A router or an eSIM keeps maps, seat reservations and translation working through the day. See our shinkansen WiFi and power outlets guide for what is available at your seat, and check our WiFi Japan page for current rental options.
