Data planning

Insider tips
- Public Wi-Fi is common but can be insecure — use your eSIM for safer, more reliable access.
- Use your eSIM to navigate JR lines, check timetables, and book Shinkansen seats via apps while on the move.
- Cherry blossom season (spring) and autumn foliage are peak times. Winter is ideal for skiing in Hokkaido; summer brings festivals and beach weather in Okinawa.
