Ohayu eSIM Data Plans for Japan

Ohayu does not offer an unlimited data eSIM plan for Japan; every plan in its catalogue has a fixed data cap.

Travelers who need substantial data can choose from high‑cap plans such as the Japan 50GB 30 days option, priced at $61.99 USD, or the Japan 20GB 30 days plan, priced at $26.49 USD. Selecting a fixed‑data plan often provides better value unless the user is an extremely heavy data consumer.

No, Ohayu does not offer a Japan eSIM that includes a phone number or SMS capability. Ohayu provides only data‑only eSIM plans for Japan, allowing travelers to use the high‑speed data connection. Popular VoIP applications such as WhatsApp, Telegram, and iMessage can be used over the data link for calls and messaging without needing a local phone number.

Ohayu provides five single‑country plans specifically for Japan and four multi‑country plans that cover Japan as part of a broader regional package. The available plans span a price range from roughly $8.49 to $61.99, while the data caps vary between 2 GB and 50 GB. These options allow travelers to choose either a dedicated Japan‑only package or a multi‑country plan that includes Japanese coverage, depending on how wide a geographic scope they need.
