Tokyo Train Alert

About Tokyo Train Alert Android App

Tokyo Train Alert is here to make sure that you never miss your stop. Take the stress out of navigating the overwhelming network of Tokyo’s trains, metros and subways with train conductor Midori-san as your companion.

Once you’ve scheduled your journey on the app, you’ll be able to watch your train’s progress live and receive an alert when you’ve reached your destination.

We make it easy for foreign tourists who don’t understand Japanese to navigate the trains, metro or subway in Tokyo. Use the app to get from the airport to your hotel, or from Shinjuku to Shibuya.

Get a push notification when the train reaches your station and see your train move along the timetable! We support all of the major train, metro and subway lines within Tokyo, such as the Yamanote line, JR lines and Marunouchi line.


Key Features

Real time departures - View the timetable of the available trains to your destination for all major Tokyo train, subway and metro lines including JR, Tokyo Metro, and Yamanote line.

Real time alerts - Get push notifications to alert you when it’s time to get off the train. Never miss your stop again! Perfect for tourists who can’t read or understand Japanese.

Real time map - See your train’s progress on the line, live

Line status warnings - Stay alert when there are delays on the line!

Even works offline - So if you’re visiting Tokyo without mobile data, you’ll be able to use the app (which will use the train’s scheduled timetable data when live data is unavailable). You don’t have to waste your money while roaming.


Top tip - Some major Tokyo JR stations provide free WiFi in the station. Use the time in the station to update the app to check for any delays!
