Japan eSIM
方案每天最低 $2.49
Japan
Esim70 connects to Japan's tier-1 carriers NTT Docomo and SoftBank, so you ride the same 5G/4G network locals use — dense, fast coverage across Tokyo, Osaka, Kyoto, and the Shinkansen corridor, with reliable signal underground in the metro and JR stations where travelers spend so much time.
Japan is one of the highest-value eSIM destinations because the local-SIM route is painful for short visits while data needs are heavy: live train routing in Google Maps, translation apps, IC-card top-ups, and restaurant lookups all lean on a steady connection. Hotspot is supported, so one plan can also cover a tablet or a travel companion's laptop.
Public Wi-Fi is genuinely widespread in convenience stores, stations, and tourist areas, so a lighter plan often stretches further than expected — keep the eSIM for navigation on the move and the gaps between hotspots. Install before you fly and it activates automatically on first connection to a Japanese network: no kiosk, no Alien Registration Card, no airport markup.

為何在這裡用 eSIM 而非當地 SIM 卡
Japan's local SIM market is famously hostile to short-term travelers — most kiosks require Alien Registration Cards, and tourist SIMs sold at airports come with high markup and time-limited validity.
免費 Wi-Fi： 廣泛可用. Free public Wi-Fi is widely available in stations, convenience stores, and tourist areas. eSIM gives you reliable coverage between hotspots.

關於 Japan 的常見問題
我的 eSIM 在新幹線和地鐵裡能用嗎？
可以——日本的網路（NTT Docomo、SoftBank）在包括新幹線在內的主要鐵路線以及大部分東京/大阪地鐵隧道中維持絕佳涵蓋。旅途的大部分時間可期待 4G/5G。
我的方案效期在 Japan 何時開始計算？
當您的 eSIM 首次連接到 Japan 當地網路時，效期才開始計算——通常是在您落地並關閉飛航模式後。提前幾天在家安裝 eSIM 不會消耗任何天數。
我可以在 Japan 把手機當作 Wi-Fi 熱點使用嗎？
可以——所有 Esim70 方案預設支援網路分享，且沒有單獨的每日上限。您的手機可以與筆電、平板或同行者的手機分享數據連線。
在 Japan，我的本國號碼還能用嗎？
可以——現代手機支援雙卡。您的本國 SIM 卡可繼續用於通話和簡訊，而 Esim70 eSIM 負責境外數據。您也可以讓 WhatsApp / iMessage 繼續綁定本國號碼。
