Nomad eSIM Data Plans for Japan

Nomad does not provide a truly unlimited data eSIM for Japan. All of the plans listed for Japan have a fixed data allowance: the “unlimited” names are marketing titles that reflect a generous daily or total limit rather than an endless high‑speed data allowance. For example, the Local Japan packages give 2GB per day for 3, 5, 7, or 10 days, and the Regional APAC packages offer 37.5GB for 5 days or 75GB for 10 days. Other fixed‑data options include 50GB for 30 days and 50GB for 45 days.

Because the data caps are fixed, speed may be throttled after the limit is reached, making these plans more cost‑effective unless a traveler needs truly unlimited high‑speed data. Nomad’s fixed‑data plans remain the only available choices for Japan.

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 features 10 single‑country plans that target Japan directly and 27 multi‑country packages that include Japan among their coverage destinations. The available options range in price from about $4.00 to $170.00, with data caps between 1 GB and 75 GB and validity periods from 3 to 365 days. Some plans use a fixed data amount (such as 5 GB, 10 GB, or 25 GB), providing a set amount of data for the entire period, while a smaller subset applies a daily data cap that accumulates each day of validity. Most packages do not offer tethering, but a few do, and that feature is noted when present.
