Nomad eSIM Data Plans for Japan

Nomad does not provide a true unlimited‑data eSIM for Japan. All Nomad plans listed for Japan have a fixed data allowance or a daily limit, and even those labeled with “unlimited” in the name offer only 2GB per day; once that limit is reached the speed is reduced to 1000 kbps.

Travelers who need a large amount of high‑speed data can choose a fixed data plan such as the Local Japan – 30 days – 50 GB plan, priced at $35.00 USD, or the Local Japan – 30 days – 20 GB plan, priced at $23.00 USD. These plans provide the specified amount of data for the full validity period and can be more cost‑effective for heavy users than a plan that caps at a lower daily data amount.

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.
