eSIM 日本
A Japan eSIM helps with rail navigation, platform changes, restaurant bookings, and translation from the moment you land. Reliable data is particularly valuable when moving between Tokyo, Kyoto, Osaka, and smaller stops where station Wi-Fi may be limited.

旅の途中のカバー
Urban coverage is typically strong in Tokyo, Osaka, Kyoto, Nagoya, Fukuoka, and Sapporo. Reception can be less consistent in mountain areas, tunnels, remote islands, and on parts of rural rail journeys, so keep tickets and accommodation details available offline.
プランの選び方と準備
Choose data based on navigation and media use rather than trip length alone. A light user relying on maps and messaging needs much less than someone uploading video or tethering a laptop. Install before departure so you do not depend on airport Wi-Fi after arrival.
