Horizon eSIM eSIM Data Plans for Japan

Horizon eSIM does not provide any unlimited data plan for Japan. The provider’s Japan‑specific plans are fixed‑data packages. For example, the Japan 50GB 180Days plan gives 50GB of data for 180 days at a price of $159.18 USD, and the APAC 20 GB / 90 days plan offers 20GB for 90 days for $63.83 USD. These fixed data plans can be more cost‑effective for most travelers, unless a user expects to consume a very large amount of data beyond these allowances.

Horizon eSIM does not provide Japan eSIM plans that include a local phone number or SMS capability. The only plans sold by Horizon eSIM for Japan are data‑only eSIMs. Travelers who need voice or messaging can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should verify that these services are accessible in Japan before making a purchase.

Horizon eSIM provides eight single‑country data plans that cover Japan, and thirteen multi‑country plans that include Japan. The plans range in data caps from 100 MB to 50 GB, with prices spanning approximately US$0.31 to US$304.64 and validity periods from 7 to 365 days. The majority of the plans offer a fixed amount of data for the entire validity period, while a small subset provides a daily data cap, allowing travelers to control usage on an per‑day basis.
