eSIMMigo eSIM Data Plans for Japan

eSIMMigo does not offer unlimited data eSIM plans for Japan.
For travelers who need substantial data, eSIMMigo provides fixed data plans. For example, a 100GB plan usable for 60 days is available for $44.99 USD, and a 50GB plan for 30 days is available for $22.30 USD. These plans impose a hard data cap and a specific validity period, so choosing a fixed data plan can be more cost‑effective unless the user is an extremely heavy data consumer.

eSIMMigo does not provide a Japan eSIM plan that includes a local phone number or SMS capability. Travelers need to use a data‑only plan, and can rely on VoIP applications such as WhatsApp, Telegram, or iMessage for voice and messaging over the data connection. Some destinations may block or restrict particular apps, so it is advisable to verify that the essential services you intend to use are accessible in Japan before purchasing.

The service catalogue lists 57 single‑country plans and 118 multi‑country plans in total, and Japan is included among the destinations covered by both types of offerings. Prices for these plans range from around $2.92 to $109.62, while data allocations span from a single gigabyte up to 100 GB, with validity periods extending from one day to a full year.
