Best Coverage Across Japan
With our eSIM you get coverage across Japan’s populated areas: from major cities like Tokyo (all 23 wards are covered with stable 5G), Yokohama, Osaka, Nagoya, and Fukuoka to suburbs and rural towns, where 4G/LTE is widely available. Mobile internet is also accessible at many iconic natural landmarks, including public areas at the base of Mount Fuji and along popular hiking trails, as well as on the beaches of Okinawa. On the islands of Honshu, Hokkaido, Kyushu, and Shikoku 5G or LTE coverage is available in most locations.
