Nomad eSIM Data Plans for Japan

Nomad does not provide a plan that offers truly unlimited high‑speed data for Japan. The plans marketed as “unlimited” actually give 2GB of 4G/5G data per day and then throttle speed to 1000kbps after that limit is reached.
Nomad’s fixed‑data options include a 50GB plan for 30 days at $35.00 USD and a 20GB plan for 30 days at $23.00 USD. These plans supply a larger total data allowance and may be more economical for travelers who need substantial data without the speed throttling that applies to the daily‑limited “unlimited” plans.

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 lists 10 single‑country plans that cover Japan and 27 multi‑country plans that include Japan in their routes. The catalog includes both fixed‑data plans and daily data‑cap options—six daily caps and thirty‑one fixed‑capacity slabs. Prices range from roughly four dollars to one hundred seventy dollars, while data caps run from one gigabyte up to fifty gigabytes, and validity periods span three to 365 days.
