A manhole is the top opening to an underground utility vault used to house an access point for making connections or performing maintenance on underground and buried public utility. It is protected by a manhole cover, a (usually metal) plug designed to prevent accidental or unauthorized access to the manhole.
Today I am going to present you some photos about how the manhole cover look like in Japan. For Japan, I always have a special feeling. They are going really crazy in some case, em maybe crazily creative. So let’s check how much detail they put on manhole cover to make it so special that I have to make a poster for it.
This is the city where the famous Japanese Carton “Detective Conan” happens. The detector Conan actually is the figure in the middle of the cover.
