eSIM for Japan: good to know
In Japan you need mobile data almost everywhere: metro and train routes, translating signs and menus, bookings. The eSIM works in Tokyo, Kyoto, Osaka and across the country on partner networks: from $3.49, 5 GB for 30 days is $9.49, a week of unlimited data is $17.99.
- There's less free street Wi-Fi than you might expect — mobile data saves the day.
- Google Maps is great for routes with transfers: it shows platforms and even the best car to board.
- You can add a Suica or PASMO transit card to Apple Wallet on iPhone and top it up from the phone.
- The camera translator (Google Translate) helps with menus and signs — it needs data or the Japanese pack downloaded.
Do I need mobile data in Japan?
It's strongly recommended: routes, transfers and translation are hard without it, and street Wi-Fi is limited.
How much data do I need for a week in Japan?
5 GB for maps and translation; 10 GB or unlimited if you post lots of photos and video.
eSIM or pocket Wi-Fi?
An eSIM needs no pickup, return or separate charging; pocket Wi-Fi is handier only for a big group.
