The small building most visitors walk past
Just inside the Niomon, set a little to the south, stands a pavilion small enough to be missed on a first visit. This is the Mizuya of Kangi-in, the roofed water station where worshippers rinse their hands and mouth before approaching the deity. It measures a single bay in each direction and covers only about 3.4 square meters, yet it repays a second glance.
The pavilion dates to the middle of the Meiji era, sometime between roughly 1883 and 1897. Its roof is a simple gable (kirizuma) laid with pantiles. The posts lean very slightly inward, a technique called uchikorobi that lends stability and a settled look, and a stone basin sits at the center for the ritual.
Modest in size, generous in detail
The Mizuya joined the national register on 2 May 2017 as one of eight structures around the Shoden hall recognized together. Its listing rests on the same ground as the others, a contribution to the historic landscape, and it fills out the picture of how the precinct was assembled over time.
What stands out is the mismatch between the building's footprint and its ornament. Bracket clusters (degumi) around the eaves carry a thick rainbow beam, and the beam itself, the large frog-leg struts (kaerumata), and the curved supporting members (shirin) all carry carving. For a shelter over a water basin, the effect is unusually rich and solid.
How to look at it
Approach as you would to purify yourself, then step back a pace. From a short distance the eaves reveal how much timber has been packed into so little span. The carpentry here echoes, at pocket scale, the ambition that runs through the whole temple.
Because it stands on the path everyone takes, the Mizuya is easy to reach and easy to photograph. Use it as intended first, and study it second.
