Japan Prepaid Data eSIM | 3GB–50GB

Select a plan

Looking for Japan total-data eSIM on native Docomo with Japan IP? DOCOMO (IIJ) total uses Docomo 4G/LTE and a Japan IP with up to about 50GB high-speed—ideal for multi-day trips when you roughly know total usage.
Why choose DOCOMO total data?
•
The simplest way: Buy a fixed total allowance and duration; native Japan IP—smoother for navigation and local apps.
•
Total high-speed + reduced-speed continue: About 3GB–50GB (see page); after high-speed ends, about 200 kbps continues.
•
Docomo coverage: Stable across Tokyo, Osaka, Kyoto, Fukuoka, Hokkaido, Okinawa, and major tourist areas.
•
Manual APN required: Set vmobile.jp; without it, signal with no data is common.
•
Hotspot + popular apps: Hotspot, ChatGPT, TikTok, Gemini, and similar apps are supported.
•
Who should choose / switch: Choose this if you want Docomo native + total-data control; if you don’t want to set APN manually, please switch to "AU KDDI Total-data plan" or "KDDI／SoftBank Total-data plan"; if you want the allowance to reset daily, please switch to "IIJ Docomo Daily plan"; if you don’t want to track usage all day, please switch to "DOCOMO Unlimited" or "AU KDDI True Unthrottled".
•
Activation tip: Install and set APN in Taiwan first; turn on mobile data after you are in coverage in Japan.

Real-world experience

Within high-speed allowance: cities often reach tens of Mbps. After that, ~200 kbps usually covers messaging/light pages; video may stutter. Without vmobile.jp you may have no data. For reference only.
