RailSense Japan

Navigate Tokyo's stations like a local.

Ground-truth navigation for Tokyo's busiest train stations, built for English-speaking travelers. Every route is verified on foot — real step counts, the exact location of every elevator and escalator, and the right gates and exits — so you spend less time lost underground and more time enjoying the city.

Overview

What it does

RailSense Japan turns Tokyo's intimidating mega-stations into something you can actually navigate. Every concourse, transfer corridor, gate, and exit is hand-walked and verified — then translated into clean, English-first diagrams that match what you'll see in front of you.

Plan your day before you land: pick the stations you'll pass through, save the right exits, and carry the whole plan offline. When you arrive, you already know which car to board, which gate to aim for, and exactly how many steps stand between you and the street.

Key features
  • Hand-verified maps of Shinjuku, Shibuya, Tokyo, Ikebukuro, and Shinagawa
  • Exit-by-exit guidance with what's actually on the other side
  • Real step counts, escalator and elevator locations on every route
  • Wheelchair, stroller, and luggage-friendly routing as a first-class option
  • Every Pokémon Center mapped, with the fastest exit from the nearest station
  • Full offline trip planner — works in the deepest basement platform

How it works

Verified spatial maps

Hand-walked station diagrams that match what you actually see on the ground — not a flat schematic.

Exit & gate guidance

Know the right exit before the train even stops — every gate labeled with what's on the other side.

Step counts & accessibility

Know exactly how many steps, escalators, and elevators are on each route. Wheelchair and stroller routing first-class.

Pokémon Center locations

Every Pokémon Center mapped, with crowd tips and the fastest exit from the nearest station.

Offline trip planner

Save your day's stations in advance — every map, gate, and note works without signal.
