Station signage is something you probably don’t think about, as long as it works. When signage doesn’t work, you notice. A lot of work is being done with Tokyo area signage in preparation for the 2020 Tokyo Olympics. Shinjuku Station signage in particular is getting a face lift that I hope to explore soon. In the above example from Asagaya station JR East uses interesting color cues, yellow for exits, green for entrances.
