Japan NTT DOCOMO Daily eSIM | High-speed 4G/5G | Japan IP | 5GB / 30GB / 100GB a Day
Select a plan
Looking for a Japan eSIM on NTT DOCOMO, not IIJ? This card is NTT DOCOMO’s own high-speed 4G/5G (Japan IP), with 5GB, 30GB, or 100GB a day. Plenty of cards say Docomo but are actually IIJ, a different company that borrows Docomo’s network. This one is Docomo itself.
Why NTT DOCOMO?
- •
The easy part: No physical SIM swap. High-speed data starts over every day, so just buy the days you’re traveling.
- •
NTT and IIJ, simply: NTT Docomo is one of Japan’s big carriers, and this card uses its own high-speed 4G/5G. IIJ Docomo is a different company that borrows Docomo’s towers. When it’s crowded, the borrowed line is more likely to slow down. Docomo’s own line is usually smoother.
- •
More data each day: Choose 5GB, 30GB, or 100GB a day. IIJ daily plans are mostly 500MB–3GB. This one is easier when you use maps, a hotspot, and video together.
- •
Still online after that: About 200 kbps once the day’s high-speed data is used, back to high speed at midnight Japan time. Texts usually still go through. HD video stutters.
- •
Native Japan IP: Traffic exits in Japan. Maps, social apps, and Japanese apps feel smoother than a Singapore-IP roaming card.
- •
One less setup step: On iPhone, scanning the QR usually fills this in. On Android, type a.apn02.net. With IIJ, you type vmobile.jp yourself on both iPhone and Android.
- •
Who should choose what: Pick this if you want Docomo’s own line and you use a lot each day. If you already know the trip total, choose NTT DOCOMO total. For light use and a lower price, choose IIJ Docomo daily. If you don’t want any setup, choose SoftBank/KDDI daily. If you don’t want to watch your data, choose AU KDDI truly uncapped.
- •
Before you start: Install it in Taiwan first. After you land and connect to NTT Docomo, turn this card’s mobile data on. That’s when the days start counting.
Real-world experience
Before the high-speed data runs out, city tests often reach tens of Mbps, and it’s usually smoother than IIJ when it’s crowded. After that, about 200 kbps still handles texts while video stutters. Android without a.apn02.net may show signal but no internet. For reference only.

Validity policy
抵達日本、連上 NTT Docomo 後才會啟用並開始計算效期。建議出發前先安裝；Android 請一併設好 APN（a.apn02.net），抵達後再開啟行動數據。iPhone 多數會自動帶入 APN。
Other information
APN 設置
iPhone 多數會自動帶入。Android 請手動將 APN 設為 a.apn02.net，才能在日本上網。IIJ Docomo 用的是另一組 APN（vmobile.jp），不要混用。
Overview
這張是 NTT DOCOMO 自己的高速 4G／5G 每日型，不是 IIJ。IIJ Docomo 是另一家公司，向 Docomo 借基地台來用。人多的時候，借來的線路比較容易變慢；Docomo 自己的通常比較順。
每天可選 5GB、30GB 或 100GB 高速。IIJ 每日型多半只有 500MB～3GB，所以這張比較適合導航、熱點和影音一起用。兩邊都是日本原生 IP；高速用完後都大約降到 200kbps，並在日本時間 0:00 恢復。
和 IIJ 的設定差在這裡：iPhone 多數會自動帶入 APN；Android 請設 a.apn02.net。IIJ 則是 iPhone 和 Android 都要手動填 vmobile.jp。若每天只用一點、想少付一點，可改選 IIJ Docomo 每日型；完全不想設定 APN，可改選 SoftBank／KDDI 雙網。
這趟總流量抓得住、不必每天重置，可改選 NTT DOCOMO 總量型。
和 IIJ Docomo 比，這張強在哪
- 網路：NTT DOCOMO 自己的高速 4G／5G。IIJ 是另一家公司，向 Docomo 借基地台
- 人多的時候：Docomo 自己的線路通常比 IIJ 順（實際速度仍看地點與人潮）
- 每日額度：5GB／30GB／100GB；IIJ 每日型多半是 500MB～3GB
- 用完之後：約 200kbps，日本時間 0:00 恢復高速（這點和 IIJ 接近）
- IP：日本原生 IP，比新加坡 IP 的漫遊卡更適合在地 App
- APN：iPhone 多數自動；Android 手動 a.apn02.net。IIJ 則兩種手機都要填 vmobile.jp
