Yesim eSIM Data Plans for Japan

Yesim offers unlimited data eSIM plans for Japan that use 5G networks. The plans come in various validity periods, from 1 day up to 80 days, and prices range from about $4.06 USD for a one‑day pass to roughly $126.29 USD for an 80‑day pass. Because the plans are labeled as unlimited, users receive no fixed data cap; however, speeds may be throttled if high‑volume usage exceeds the Fair Usage Policy, so speeds could be reduced after extended heavy usage. Travelers who want to confirm the exact amount of data that remains at normal speed can contact Yesim directly.

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 13 single‑country data plans for Japan and 25 multi‑country plans that include Japan. The single‑country options range in price from about $4.04 to $229.50, with data caps from 1 GB up to unlimited and validity periods between 1 and 365 days. The multi‑country plans cover Japan as part of a broader itinerary, and they follow a similar price and data‑cap range while allowing travel between several destinations.
