Nomad eSIM Data Plans for Japan

Nomad does not provide a true unlimited data eSIM plan for Japan. Every plan listed for Japan includes a specific data allowance, such as 2 GB per day for up to 10 days or a fixed 50 GB for 45 days. The term “unlimited” appears only in the plan names and does not indicate unlimited high‑speed data; after the set amount is used the speed is reduced rather than remaining unlimited. For travelers who need a large data allocation, Nomad offers fixed‑data options like the 50 GB 45‑day plan or the 75 GB 10‑day regional APAC plan, which can be more cost‑effective than relying on a nominal unlimited name.

Nomad does not provide a Japan eSIM that includes a local phone number or SMS capability. The provider only offers data‑only eSIM plans for Japan, so if you need to place calls or send texts you will need to use internet‑based messaging and calling apps such as WhatsApp, Telegram or iMessage over the data connection.

Nomad’s portfolio for Japan includes 10 single‑country plans and 27 multi‑country plans that cover Japan.
The plans come in two main types: fixed data caps, which supply a set amount of data for the entire validity period, and daily data caps, where a specified amount of data is reset each day; Nomad offers 33 fixed‑data plans and 4 daily‑cap plans across all its offerings.
Overall, the available plans range in price from about USD 4.00 to USD 170.00 and in data capacity from 1 GB up to 75 GB, with validity periods spanning from 3 days to 365 days.
