The railways are placed between the two (North and South) buildings, under a glass roof. At the 5th floor there's a spectacular connecting passage named Toki-no-hiroba Plaza because of two large clocks, one golden (in the middle of the photo) and one silver. The Plaza architecture was made by Mitooka Eiji, the same artist who designed the elegant Sakura Shinkansen.
