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 currently offers 25 single-country data plans specifically for Japan, alongside 24 plans that provide multi-country coverage including Japan. These plans range in price from approximately $3.94 to $325.10 and offer data allowances from 1GB up to 100GB. Many of their plans feature a daily data cap, while others provide a fixed data allowance. Plans are valid for periods ranging from 1 to 90 days, and tethering is permitted with some options.
