Knowing the stations near your hotel and destination makes a Tokyo subway map easier to read. Dotori Tokyo Metro is an Android app with the nine Tokyo Metro and four Toei subway lines. Its map, station search and diagram routes work offline. You can explore a journey without a mobile connection.
Find a familiar name and compare the Japanese
A station name in a travel plan may look different from the Japanese on a sign. Station names come in Japanese, English, Korean and Simplified or Traditional Chinese. Search by station name or station number, then find that station on the map. A large Japanese station-name card helps you compare the local spelling with the signs around you.
Zoom in to examine a section of the map, or highlight a line to separate it from the others. See how a destination connects to the surrounding stations. The diagram describes the subway network. The length of a line on the screen does not represent the distance you will travel or walk.
Choose two stations to check a diagram route
Start with the station near your hotel and one place you want to visit. Select departure and arrival stations to find a route within the bundled subway network. The result shows the stops and highlights sections on the map. The basic process is:
- Search for the departure station by name or station number.
- Set the station as your departure point.
- Find the destination and set it as your arrival point.
- Check the stops and highlighted sections in the result.
Routes prioritize fewer line changes, then fewer stops. A line change count is not a count of actual train changes. You may need to change trains while staying on the same line. Always follow station signs and operator announcements. The app does not calculate a journey for a particular train or its current service pattern.
Check the coverage before using it for a trip
Tokyo has railways beyond these subway lines. The route network covers Tokyo Metro and Toei subway services. JR and private railways are outside its coverage. Check those parts of an airport, hotel or sightseeing journey separately. The app does not provide train travel times, full departure timetables or live arrivals.
You can also check fare information and directional first/last trains for the four Toei lines. Read the fare conditions and data reference date shown in the app. First/last train information is unavailable for the nine Tokyo Metro lines. A first/last summary is different from a full departure timetable.
Nearby-station lookup is optional and requires location permission. It covers Tokyo Metro and Toei stations with bundled geographic coordinates. It does not cover JR or private railway stations. You can use the map, search and departure/arrival selection without granting location access. Schematic positions do not represent geographic coordinates or walking distance.
Offline support applies to the map, station searches and diagram routes. Banner advertising, privacy choices and Google Play app updates need a network connection. There is no account to create, and searches and route selections are processed on the device. Dotori Tokyo Metro is an independently developed app, not an official app of the railway operators.
Explore one journey before you leave
Dotori Tokyo Metro helps you read 13 subway lines and compare station names and connections. Check fare conditions and operator guidance before boarding. Before your trip, select the station near your hotel and your first destination. This is a useful way to learn what the app covers.
