A hexagonal water house for purification
Within the Daishi-den precinct stands a small building where worshippers rinse their hands and mouths before praying: the Mizuya, or water pavilion, of the Sōso Daishi-den. A hexagonal plan shelters a round flower-shaped water basin, and a sacred jewel finial sits atop its pantile roof. At just 4.4 square meters it is tiny, yet it plays a role the Daishi-den space cannot do without.
Like the ornate gate, it was set up during the Taishō-era arrangement of the precinct. Standing opposite the everyday gate, it forms one half of a paired composition in the view along the north side of the hall's grounds.
A small frame set out in six sides
Six posts, tied together by nageshi rails, support a hexagonal ring of purlins. Binding the posts with rails, the builders resolved the six-sided plan crisply. The round flower-shaped basin at the center answers the hexagon of the roof, so that even at this small scale the building carries an ordered, geometric appeal.
The jewel finial gives the roof a firm crown, lifting a plain utility building to a design worthy of the Daishi-den's standing. Holding ornament in check, it makes its impression through the beauty of its shape. It was listed on August 28, 2001.
The point that completes the scene
The water pavilion faces the everyday gate and is essential to the view along the north side of the Daishi-den precinct. Small as it is, its position and form hold the balance of the whole space. As a matter of ritual, too, the proper sequence is to purify the hands here before proceeding to the hall.
It is easily overlooked, but attention to concrete forms, the hexagonal plan and the flower-shaped basin, conveys the fineness of the design. Anyone savoring the Daishi-den space with care will want to pause at this point as well.
