Travel tips
Japan connectivity tips
- Install your eSIM on hotel or airport Wi‑Fi before leaving the terminal — Japanese carriers attach quickly once the line is enabled.
- IC cards (Suica/Pasmo) and translation apps are daily drivers; keep data on for maps between stations.
- Convenience-store Wi‑Fi exists, but prepaid eSIM data is far more reliable for same-day train changes.
How much data: Tokyo/Osaka sightseeing with maps + translate is commonly 3–5 GB per week. Heavy photo uploads or hotspotting a laptop needs 10 GB+.
