Japan eSIMs
Japan is the single most searched eSIM destination, and it has quirks worth knowing before you buy. Coverage is excellent on all three national networks, but they are not interchangeable: NTT Docomo and KDDI reach rural Hokkaido and mountain routes that SoftBank thins out on, and some cheap plans ride only one of them. Unlimited plans are common and genuinely fast. A few providers issue a Japanese phone number, which matters if you are booking restaurants or renting a car. Listings here name the underlying network, say whether the plan is data-only, and give the real daily cost at typical trip lengths.
