Nomad eSIM Data Plans for Japan

Nomad does not provide a truly unlimited data eSIM plan for Japan. The plans that include “unlimited” in their name actually offer a capped amount of high‑speed data—2 GB per day—after which the speed is reduced. For travelers who need larger data allowances, Nomad offers fixed‑data plans such as 50 GB for 45 days at $57.00 USD or 20 GB for 45 days at $25.00 USD. Choosing a fixed‑data plan can be more cost‑effective unless a user expects to use far more data than the 2 GB per day limits.

Nomad does not provide Japan eSIM plans that include a phone number or SMS capability. All of the plans sold to travelers cover only high‑speed data, with no outbound or inbound voice or text services included.

If you need to keep in touch while in Japan, you can rely on popular VoIP applications such as WhatsApp, Telegram, or iMessage, which function over a data connection and do not require a local phone number or SMS ability.

Nomad lists 10 single‑country plans that cover Japan only and 26 multi‑country plans that include Japan among their network reach. The available plans range in price from $4 to $170, with data caps from 1 GB up to 50 GB and validity periods from 3 to 365 days. Within these offerings, four plans apply a daily data cap while the remaining thirty‑two provide a fixed total data allowance, so travelers can choose between a consistent daily usage limit or a set amount of data for the entire validity period.
