Higashiyamato City has created twelve designs of custom-designed manhole covers based around its tourism mascot, Umabee. The designs also incorporate attractive spots in the city, including Tama Lake and other lush nature scenes, historic landmarks, and monuments.
These manhole covers are located in 24 locations throughout the city near thematically appropriate spots. Taking a tour of the manhole locations will enable you to experience the attractiveness and appeal of Higashiyamato City and its natural environment.
