At large shrines, the temizuya is often built as a decorated pavilion, and the one from the Rinnō-ji Taiyuin Mausoleum in Nikko is the most beautiful construction of this type I have encountered until now.
Located near the Nitenmon gate, the Rinnō-ji Taiyuin Temizuya is lavishly decorated with exquisite sculptures and features a roof built in a style called Kiritsuma, sustained by 12 granite pillars. Inside, on the ceiling, there is a big painting of a dragon, made by Kano Yasunobu, a member of one of the most famous schools of Japanese painting, Kanō-ha.
The dragon's image is reflected on the water surface, hence the name: Mizukagamino-ryu, the Dragon in the water mirror:
