Japan Travel: Data, Transit IC Cards & Everyday Apps (2026)
Typical connectivity stack
Tourists combine a pocket Wi‑Fi or data SIM/eSIM with a transit IC (Suica, PASMO, ICOCA…) for trains and konbini taps. Apple Wallet Suica works on supported devices; Android varies by model and region.
Maps & transit apps
Google Maps works well for urban transit; dedicated Japan transit planners (search stores for “Japan transit”) can be more precise on timetables. Use translation tools for restaurant QR menus.
