Strengthening Our Network as an ICT Platform in Tourism

LocationsEasy Connections Even at Japan’s World Heritage Sites, Natural Treasures and Tourism Locations,

Like the Upward Path and the Summit of Mt. Fuji, the 88 Temples in the Shikoku Pilgrimage, from Shiretoko in the North to Ryukyu Kingdom artifacts in the South

*Depending on signal conditions, even within the LTE area communications may be via 3G or in some cases, not available. *Clockwise from upper left, Mt. Fuji, Ryozenji (sacred places of Shikoku), Oshinkoshin Falls (Shiretoko, Hokkaido), Tomioka Silk Mill, Shirakawa-go, Shurijo Castle Park (Okinawa)
