The SIM Shop eSIM Data Plans for Japan

Yes, The SIM Shop offers unlimited data eSIM plans for Japan. The unlimited plans are priced from $9.00 USD for a 3‑day option to $26.38 USD for a 10‑day option, and each plan allows up to 10Mbps of speed with a maximum speed of 10Mbps stated in the plan features. The plans are available with validity periods of 3, 5, 7, or 10 days.

Speeds may be throttled after heavy usage, and while the plans do not have a formal fair‑usage threshold, users should contact The SIM Shop to confirm how FUP may be applied and the typical amount of data available at normal speed.

The SIM Shop does not provide a Japan eSIM that includes a local phone number or SMS capabilities; only data‑only plans are available. Travelers who need voice or messaging can use VoIP apps such as WhatsApp, Telegram, or iMessage over the data connection, but some destinations may block or restrict these services, so users should verify access in Japan before purchasing.

The SIM Shop lists 23 single‑country data plans and 55 multi‑country data plans for use in Japan. The single‑country options are primarily fixed‑data plans that provide a set data amount for the duration of the validity period, while the multi‑country bundle plans use a daily data cap that can be applied to multiple destinations as needed. Across all Japan‑focused offerings the price ranges from about $3.44 to $129.25 and the data caps vary between 1 GB and unlimited, giving travelers a wide range of choices to match the length of their trip, from a single day up to 180 days.
