Esimatic eSIM Data Plans for Japan

Esimatic does not provide an unlimited data eSIM for Japan. The company offers fixed‑data plans that range from 20GB to 100GB for 30 days. For example, the 100GB plan costs $132.49 USD, the 50GB plan is $59.99 USD, and the 20GB plan is $25.89 USD, all of which allow t‑ethering and provide 5G coverage within Japan.

Choosing a fixed‑data plan is typically more cost‑effective for travelers who need a substantial amount of data but are not extremely heavy users. These plans give clear data limits and validity periods, letting users manage their usage without worry of overages.

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.
