shibaSIM eSIM Data Plans for Japan

shibaSIM does not provide an unlimited data eSIM for Japan. All of their available plans for the country have a specified data cap, with their largest fixed bundles offering 50GB. Users seeking a larger data allowance can select one of these fixed plans, such as 50GB for 30 days or 30GB for 3 days, which cover the entire country. Choosing a fixed data plan may be more cost‑effective for most travelers unless an extremely heavy data consumption is required.

shibaSIM does not offer an eSIM with a phone number or SMS capability for Japan; only data‑only plans are available. Travelers can still use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection for voice and messaging, but some destinations may block or restrict certain services, so it is advisable to confirm the availability of these apps in Japan before purchasing a plan.

shibaSIM offers 51 single‑country data plans that cover Japan and 69 multi‑country plans that include Japan. The plans are available in two main styles: fixed data amounts, ranging from 500 MB to 50 GB over a validity of 1–30 days, and daily data caps, which allow a certain amount of data each day for the same validity period. Prices for Japanese plans vary from roughly $4.63 up to $114.53, giving travelers a broad range of options to choose from.
