No seriously: a museum devoted to ramen (in all honesty, it actually sounds pretty awesome). This map is found on the main floor of the museum, where nine restaurants serve different styles of ramen from Japan and around the world in a faithfully recreated Japanese streetscape from 1958 – the year that instant ramen was invented.

As to which transit system it represents, I can’t even begin to guess. The original post on Flickr posits Tokyo, but the museum is closer to Yokohama… But I’m pretty sure that one of you will be able to help out and translate/locate for me.

EDIT: And… that took all of 10 minutes to work out. Thanks to psylin for translating and finding out that the red station is “Narutobashi”, a fictional station and area that the replica streetscape represents. 

However, I am almost certain that the numbers in the station dots represent the fare from the red “You Are Here” dot.
