Ohayu eSIM Data Plans for Japan

Ohayu does not have an unlimited data eSIM plan for Japan. Travelers who need large data allowances can choose from fixed‑data plans, such as the Japan 50GB 30 days plan priced at $61.99 USD, the 25GB monthly plan at $49.49 USD, the Japan 20GB 30 days plan at $26.49 USD, the 15GB monthly plan at $39.99 USD, or the Japan 10GB 30 days plan at $18.99 USD. These options all provide 5G connectivity in Japan and can be more cost‑effective for most users unless an extremely heavy data consumer is expected.

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 offers a total of 10 distinct data plans for use in Japan. Six of these are single‑country plans that give you coverage only in Japan, while four are multi‑country plans that include Japan along with other destinations. The plans are priced between $0.49 and $61.99 US dollars and provide data caps ranging from 1 GB up to 50 GB, with validity periods that can span from a single day to 30 days. Some plans allow tethering and may be limited to new users, but overall the options cover a wide range of data needs and price points.
