Japan eSIM FAQ
Does Japan have a Local Network eSIM?
Yes. Polaris eSIM offers Local Network plans in Japan that connect directly to local carrier towers — no detours, with the same speed experience as locals. Roaming plans are also available as a backup option.
How do I buy and install a Japan eSIM?
Three steps: (1) choose a plan online and pay; (2) receive your installation QR code by email; (3) scan it after arriving in Japan to activate with one tap, turn on mobile data and you're online. Everything is done online — no physical SIM swap needed.
How many days and how much data should I get for a trip to Japan?
Pick a total-data plan that matches your trip length — it's the best value. Japan plans come in a wide range of data sizes and durations; if you'll use navigation, streaming or hotspot sharing heavily, go for a larger data allowance for extra peace of mind.
How is the validity period of a Japan eSIM calculated?
It depends on the plan: some start counting days from your first data use, others from the moment installation completes. Each plan page clearly lists its rule, so you can check before buying.
Does my phone support eSIM?
Most recent iPhones (XS and later), Google Pixel and Samsung flagship phones support eSIM. You can use the Polaris eSIM device checker to quickly confirm whether your phone is supported. Check if your phone is supported →
