katsuyama castle museum (勝山城博物館, "katsuyama-jō hakubutsukan") is a museum that is in the city of katsuyama in fukui prefecture in japan. the museum was finished on july 19, 1992. it is considered to be the tallest castle in japan, at 57.8 meters, but it is not a castle because it does not have a "tenshu" or "tenshukaku"–a “keep tower” (tower to defend from enemies). it was built to look like the himeji castle. the museum also stands out because it has dragons cut into its foundation stone, which is unusual for a japanese castle.
