WiFi Map eSIM Data Plans for Japan

WiFi Map does not provide an unlimited data eSIM for Japan. All of the available plans in the Japanese market are capped, with the largest offering 25 GB for 30 days. Travelers who need a larger data allowance can choose one of the fixed‑cap options, such as the 25 GB plan priced at $54.90 USD, or the 10 GB plan at $29.99 USD; each gives access to the same network coverage throughout Japan plus additional countries. While fixed‑cap plans can be a more economical choice for most users, extremely heavy data users may prefer a different provider that offers truly unlimited data.

WiFi Map does not provide a phone number or any SMS capability for its Japan eSIM plans. Only data‑only plans are offered. Travelers needing voice or text communication can rely on internet‑based services such as WhatsApp, Telegram, or iMessage, which work over the data connection without needing a local phone number or SMS package.

WiFi Map currently offers five data plans with coverage including Japan, which are designed for use across multiple countries. These plans range in price from approximately $4.99 to $54.90 and offer data allowances from 1GB to 25GB. It’s important to note that WiFi Map does not offer single-country data plans specifically for Japan. These multi-country options typically provide data for a duration of 30 days.
