Ohayu eSIM Data Plans for Japan

Ohayu does not provide any unlimited data eSIM plans for Japan. Instead, their available plans are fixed‑data options. For example, the “Japan 50GB 30 days” plan offers 50GB of high‑speed data for 30 days, while the “Japan 20GB 30 days” plan offers 20GB for the same period. These plans are priced at $53.99 USD and $22.99 USD respectively and include tethering and 5G coverage within Japan. Choosing a fixed data plan can be more cost‑effective for most travelers unless you anticipate consuming an extremely high volume of data.

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.
