Train lines/stations visibility in Japan

[karlcow]

I understand that the map is intended to be black and white only. But currently the map is very hard to use in Japan. There is not that much labeling such as the ku (区 - administrative area), and train lines and stations do not really appear. Train infrastructure is one of the main keys for orientation in Japan. Part of its cultural artifacts. It would be cool if there was a way to make them more visible.
