Nomad eSIM Data Plans for Japan

Nomad does not provide a truly unlimited data eSIM for Japan. The plans that carry “unlimited” in their name actually offer 2 GB per day and after that limit the speed is reduced to 1000 kbps, so users receive a capped amount of high‑speed data.

Travelers who need more data can choose one of Nomad’s fixed data plans. For example, a 50 GB eSIM is available for 30 days at $35.00 USD and a 20 GB plan is offered for 30 days at $23.00 USD. These plans give a larger total data allowance and can be more cost effective unless the user requires very high daily usage.

Nomad does not provide an eSIM for Japan that includes a local phone number or SMS functionality. The plans it offers for Japan are data‑only, so travelers who need voice or text messages must rely on internet‑based messaging and calling apps.

For most travelers, WhatsApp, Telegram, iMessage and other VoIP services can be used over an internet connection. However, some destinations may block or restrict specific services, so it is advisable to confirm that the apps you plan to use are accessible in Japan before purchasing an eSIM.

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.
