Yesim eSIM Data Plans for Japan

Yesim offers unlimited data eSIM plans for Japan that use 5G network. The plans are available for validity periods from 1 day to 30 days, with prices ranging from $4.30 to $52.24 USD, and all include tethering. Normal speeds may be capped and could be subject to throttling.

Because of a Fair Usage Policy, speeds may be reduced after heavy usage. If you are concerned about potential speed restrictions or want details about the amount of data that remains at normal speed, contact Yesim directly to confirm the policy for the specific plan you intend to purchase.

Yesim does not offer a Japan eSIM plan that includes a phone number or SMS capability. Travelers can purchase data-only plans for use with VoIP applications such as WhatsApp, Telegram, or iMessage, which provide voice calling and messaging over the internet.

Yesim offers 9 single‑country data plans that cover Japan and an additional 25 multi‑country plans that include Japan. The plans vary in validity from 1 to 365 days and in data from 1 GB up to unlimited, with prices ranging roughly from $4.30 to $231.01. Some of the offerings are fixed data bundles, while others impose a daily data cap; the overall price and data ranges are similar across both types.
