I saw an advertisement on the train for a new iPhone app developed by Tokyo Metro, so I decided to download it. You won’t be able to ditch your Jorudan (Norikae Annai) app just yet, but it’s a worthy addition to your tool set for navigating around Tokyo. You can search for your nearest station (Metro only), explore the map of the Tokyo Metro network, find information about in-station facilities and exits, see a map of the inside of each station, and of course plan your journey from one place to another by Metro.
When you fire up the app, you are presented with a screen showing the symbol for each metro line. From here, clicking on the appropriate icon will give you information on service disruptions. This page is therefore totally useless unless in the event of some huge natural disaster as I’ve never experienced any service disruptions during my journey in the 3+ years I’ve been here. Another word of warning is that you will probably need to read some Japanese to use this app properly. Most of the functions are pretty self-explanatory, but the route planner is somewhat hard to find, but if you tap around you should work it all out.
As I said, this won’t replace your main Tokyo train app, because you can’t get the time of the next train and you can’t get the time of the all-important last train. Also, it doesn’t cover any other lines apart from the Tokyo Metro. It’s still worth downloading though I think, and the design is not too bad (better than Jorudan for sure).
