Select a plan

Looking for Japan daily eSIM on native Docomo with Japan IP? IIJ Docomo daily uses Docomo 4G/LTE and a Japan IP with a daily high-speed reset—ideal if you prefer Docomo coverage and can set APN manually.
Why choose IIJ Docomo daily?
•
Why it's easier: Native Japan IP helps maps and local services; just pick daily allowance by trip length.
•
Daily high-speed allowance: Choose 500MB / 1GB / 2GB / 3GB per day; after use, speeds drop to about 200/ by plan and reset next day.
•
Manual APN required: Set vmobile.jp after install (reminded before purchase). Without it, signal with no data is common.
•
Hotspot supported: Hotspot sharing works; ChatGPT/TikTok/Gemini depend on the live network.
•
誰適合／誰改選:要 Docomo 原生選這款；若不想手動 APN，改選「SoftBank／KDDI 每日型」；已抓得住總流量改選「DOCOMO 總量型」；真．不限速吃到飽改選「DOCOMO 吃到飽」或「AU KDDI 真．不限速」。
•
Activation tip: Install and set APN in Taiwan first; enable when you connect after arriving in Japan.

Real-world experience

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