Esimatic eSIM Data Plans for Japan

Esimatic does not provide an unlimited data eSIM plan for Japan. All available plans have defined data caps, the largest being 100 GB for 30 days at $114.99 USD and a 50 GB plan for 30 days at $59.99 USD. Users who need more data can choose a fixed‑amount plan such as the 100 GB option, which may be more cost‑effective unless their consumption is extremely high.

Esimatic does not provide a Japan eSIM that includes a local phone number or the ability to send or receive SMS messages. The provider only offers data‑only eSIM plans for Japan. Travelers who need voice or messaging can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection.

Esimatic offers 49 distinct data plans for Japan, comprising 25 single‑country and 24 multi‑country options. Prices run from $3.99 to $325.10, with data allocations from 1 GB up to 100 GB and validity periods ranging from one to ninety days. Some plans feature a daily data cap—providing a set amount of data each day—while others use a fixed data cap that applies for the entire validity period; both types may allow tethering.
