Yesim eSIM Data Plans for Japan

Yesim provides unlimited data eSIM plans for Japan that can be purchased for anywhere from 1 day to 80 days, with prices ranging from $4.23 USD for a 1‑day plan to $227.66 USD for an 80‑day plan. Each plan allows tethering and is shipped on a 5G network, but a fair‑usage policy applies, meaning speeds may be throttled if heavy usage occurs.

Users who want to confirm the exact amount of data that remains at full speed under the fair‑usage policy, or who have concerns about potential speed restrictions, should contact Yesim directly for up‑to‑date information.

Yesim does not offer any Japan eSIM plan that includes a phone number or SMS capability. Travelers can only purchase data‑only eSIMs from Yesim for Japan. Virtual or VoIP applications such as WhatsApp, Telegram, and iMessage can usually be used over the data connection for voice and text communication, but availability of these services may be limited or blocked in Japan. Travelers should verify that the specific apps they intend to use are accessible in Japan before purchasing a Yesim eSIM plan.

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.
