Japan

Japan draws visitors for city breaks in Tokyo and Osaka, temple stays in Kyoto, ski seasons in Hokkaido and long-running business relationships. Getting around means rail transfers, restaurant reservations and reading signage that is not always in English, so travellers lean on maps and translation from the moment they land. A prepaid eSIM for Japan puts that connection on the phone you already carry, with no counter queue and no physical SIM to swap.
