Wherever you are in Japan, there's sightseeing to be done on the street. Literally.
The variety of images is impressive. Nature makes a big appearance, as trees and birds are especially common throughout the nation's prefectures. Cherry blossom trees are especially frequent. Also appearing are dragonflies, deer, cranes, and other animals that are either locally common or well-known in the national mythology.
There's also a high number of firefighter-themed manhole covers. Those covers give firefighters easy access to water in case of emergencies.
Thanks to OpenCage for the cover image!
