Ohayu eSIM Data Plans for Japan

Ohayu does not provide an unlimited data eSIM plan for Japan. Travelers who need substantial data can choose from fixed‑amount plans instead, such as the 50GB 30 days plan or the 25GB Monthly plan, both of which are priced at $61.99 USD and $49.49 USD respectively and offer 4G, 5G coverage. These options can be more cost‑effective for most users, though very heavy data consumers may find a larger allowance more appropriate.

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.
