Japan Travel Tips

  • Must-see hotspots

    Tokyo (Shibuya, Shinjuku, Asakusa), Kyoto (Fushimi Inari, Kiyomizu-dera), Osaka Dotonbori, Mount Fuji, Hokkaido's national parks, Hiroshima Peace Memorial, Okinawa beaches, and onsen towns like Hakone.

  • Data planning

    Plan for 3–6 GB/week for typical travel use. Increase if you stream video or work remotely. You can top up instantly through Simology when needed.

  • 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.
