About Japan

Japan's prepaid SIM market is tourist-unfriendly — most contracts require a Japanese address and a hanko seal. A roamgo eSIM works around all of it: install at home, activate at Narita or Kansai, and you're navigating the Tokyo subway map within minutes of landing.

Best for: First-time Tokyo visitors needing Google Translate and Tabelog; bullet-train travellers between Tokyo, Kyoto, and Osaka; ski-season trips to Niseko or Hakuba.
Networks: Roams onto NTT Docomo, SoftBank, and au by KDDI. Docomo has the strongest coverage in mountainous areas (Mt Fuji climbers, ski resorts); SoftBank tends to be fastest in central Tokyo.
Travel tip: 5G is rolling out fast in the Greater Tokyo and Osaka areas but rural prefectures stay 4G LTE — both are fast enough for video calls and offline-map downloads.
