MicroEsim eSIM Data Plans for Japan

Yes, MicroEsim sells unlimited data eSIM plans for Japan. The plans range in price from about $2.13 for a 1‑day plan to roughly $68.62 for a 30‑day plan, and the validity period can be as short as 1 day or as long as 30 days.

All unlimited plans are delivered over 5G and may be subject to a fair‑usage policy; speeds can be throttled after heavy use, with a maximum speed of 10000kbps. If you need confirmation of the exact throttling thresholds or typical data available at normal speed, contact MicroEsim directly.

MicroEsim does not provide a Japan eSIM plan that includes a local phone number or SMS service. The provider offers only data‑only eSIMs. Travelers who need voice or text communication can use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection, but they should verify that these services are accessible in Japan before purchasing, as some destinations may block or restrict certain apps.

MicroEsim offers 120 single‑country plans and 97 multi‑country plans for Japan. The available plans range in price from $0.81 to $165.24 and provide data caps from 500 MB up to unlimited, with validity periods between 1 and 60 days. In addition to the overall data cap options, MicroEsim provides both daily data cap plans (116 in total) and fixed data cap plans (101 in total), allowing travelers to choose between a set amount of data for the entire validity period or a daily data allowance that resets each day.
