eSimy eSIM Data Plans for Japan

eSimy does not provide an unlimited data eSIM plan for Japan. Travelers who need a large amount of data can choose fixed‑data options such as the Japan‑50GB plan valid for 90 days, the Japan‑20GB plan valid for 30 days, or the Global Explorer‑100GB plan valid for 365 days. These fixed plans offer the largest data allowances listed and may be more cost‑effective for those who use data heavily, though they are not unlimited.

eSimy does not provide eSIM plans for Japan that include a local phone number or SMS capability. The provider only offers data‑only eSIMs in this country, so travelers must rely on internet connectivity to communicate. Popular VoIP applications such as WhatsApp, Telegram, and iMessage can be used over the data connection for voice and text communication.

eSimy offers a portfolio of data plans in Japan that includes six single‑country options and ten multi‑country options. The single‑country plans cover only Japan, while the multi‑country plans allow the data to be used in Japan plus additional destinations. The plans span a price range from about $4.06 up to $348.66, with data caps that vary from as little as 1 GB to as much as 100 GB. Validity periods for the plans are between 7 and 365 days, and a number of the plans support tethering.
