Yesim eSIM Data Plans for Japan

Yesim offers unlimited data eSIM plans for Japan, with validity periods ranging from 1 day to 30 days. Prices for these unlimited plans start at $8.11 USD for a 1‑day plan and go up to $63.75 USD for a 30‑day plan, all available on 5G networks. Each unlimited plan notes that normal speed may be throttled and that a fair‑usage policy could reduce speeds after heavy use; travelers who are concerned about speed restrictions are advised to contact Yesim directly for confirmation of the policy and typical data available at full speed.

Yesim does not provide any eSIM plans that include a phone number or SMS for Japan. Only data‑only eSIM options are offered. Travelers can use internet‑based messaging and calling apps such as WhatsApp, Telegram, and iMessage over the data connection to communicate while in Japan.

Yesim provides 8 single‑country plans and 21 multi‑country plans for Japan. The plans cover a price spectrum from roughly $8 to $126 and data caps from 5 GB up to unlimited. Validity periods vary from 1 to 365 days. Tethering is permitted on many plans, though speeds may be throttled.
