NTT docomo 5G and SoftBank 5G cover Tokyo, Kyoto, Osaka and the Shinkansen corridor between them with reliable data for Suica card taps, Google Maps walks through Asakusa and Fushimi Inari, and Tabelog restaurant reservations. Signal holds across the entire Yamanote Line above ground and inside the modern JR Tokyo Station concourse, drops inside the deeper wooden halls of Kyoto's older temples where the heavy tile roofs and ancient beams block reception, and weakens on the rural stretches between Shin-Hakodate-Hokuto and Hakodate where the long Shinkansen tunnels and the mountainous terrain reduce the line of sight to the nearest tower.

Yes. eSIM offers instant activation without visiting a store. Coverage matches physical SIMs in covered areas.
Yes. 5G works on the Tokaido Shinkansen between Tokyo, Kyoto and Osaka for streaming and messaging, but expect brief signal drops inside the mountain tunnels that can last up to five minutes. We recommend downloading offline maps and your JR Pass app before boarding because the rural mountain stretches and the onsen towns outside the major cities have thinner coverage. Your eSIM is useful for booking Tabelog restaurants, navigating the metro with Google Maps, and paying with Suica at convenience stores. Note that Japan's IC card system requires a separate physical Suica or PASMO card; your eSIM keeps the data connection running while you tap the IC card on the gates.
Yes. 5G works on most Tokyo Metro and Toei Subway lines above ground and inside the modern station buildings for navigation and messaging, but expect drops in the deeper tunnels between stations, especially on the deeper Marunouchi and Hibiya lines. We recommend downloading offline maps of the metro system before boarding because the underground stretches lose signal quickly. Your eSIM is useful for navigating the JR Yamanote Line with Google Maps, booking Tabelog restaurants, and translating menus with Papago. Note that Suica and PASMO IC cards require a physical card from the station vending machines; your eSIM keeps the data running while you tap the card on the gates.
Yes. 5G is excellent at Universal Studios Japan and the surrounding Tempozan bay area for app bookings and Super Nintendo World reservations. We recommend downloading the official USJ app before entering the park because the queue apps need a stable connection and the deeper rides have momentary drops. Your eSIM is useful for booking Tabelog restaurants in Dotonbori after the park, navigating the JR Yumesaki Line back to central Osaka, and paying with ICOCA at convenience stores. Note that ICOCA requires a physical card from the JR station vending machines; your eSIM keeps the data running while you tap the card on the gates.
Yes. 5G works at the lower Fushimi Inari complex for navigation and photos, but the signal weakens as you climb the mountain trails above the Yotsutsuji intersection because the forested terrain and the elevation reduce coverage. We recommend downloading offline maps and the official Kyoto City Bus app before starting the hike because the upper shrine has thin coverage. Your eSIM is useful for booking Tabelog kaiseki dinners in Gion, navigating the Kyoto City Bus with Google Maps, and paying with ICOCA at convenience stores. Note that ICOCA requires a physical card from the station vending machines; your eSIM keeps the data running while you tap the card on the bus readers.
