Pointlessly Down and Up Again…
Bizarre detour in the underground tunnels near Ginza Station.
First thought was it might be designed to prevent people bumping their heads on the low ceiling as they walk on that side of the passageway.
The actual effect is that it simply discourages people from walking there at all – which I guess achieves the desired result, but in a very expensive and indirect way.
But, given that numerous similar “low ceiling” spots around Tokyo simply use striped cushions to prevent headsmack injury, I do wonder if it serves another purpose?
