When one of his vassals asked Shingen, `Why do you call the toilet Yama (mountain) ?', Shingen gave a witty answer, `Because there is always Kusaki (it has two meanings; 草木: plants, and 臭き: bad smell, in different characters) in Yama (mountain).'
家臣が「何故、厠を山と言うのでしょう?」と尋ねた所、信玄は「山には常に、草木（臭き）が絶えぬから」と機知に富んだ回答をしている。
