A Sanctuary That Began Its Life at Ise
Oka Shrine Main Hall (乎加神社本殿, Oka Jinja Honden) is a small Shinmei-zukuri sanctuary of the early Meiji era at the back of Oka Shrine in Jingocho, Higashiomi City, Shiga Prefecture, moved to the site in 1892 and registered as a Registered Tangible Cultural Property on 18 March 2003. The Agency for Cultural Affairs records that it was a building of one of the auxiliary sanctuaries of Ise Jingu, handed over when Ise carried out its periodic rebuilding in 1889, and re-erected here three years later.
Built at Ise, then, in the first years of Meiji. Of the six structures registered at Oka Shrine, it is the oldest.
Ise rebuilds its sanctuaries every twenty years, and a retired building does not always go to waste; some are given to other shrines. The Oka Shrine Main Hall is one of those. The Agency's description does not say which auxiliary sanctuary it came from, and it presents the story of the transfer as tradition rather than as documented fact. That is the right spirit in which to read it.
Why It Was Registered
The hall was registered under the criterion of serving as a model of design. Only two of the six structures here qualified on that ground: this one and the Offering Hall in front of it.
It measures 3 by 2 bays and covers 20 square metres. At each gable end a free-standing ridge post, the Munamochi-bashira, rises clear of the wall and carries the ridge beam directly. The ridge is crowned by crossed Chigi finials and seven Katsuogi billets. A veranda runs around all four sides, and the walls are plain boards on every side except the front.
There is no paint and no bracketing. The Ise manner makes its point by leaving things out, and a building like this shows exactly how that manner was put together in timber; that is presumably what the registration recognises.
The roofing material is recorded inconsistently. The Agency's explanatory text describes a roof of cypress bark, Hiwadabuki, while the structural summary on the same record lists copper sheet. A later reroofing could explain the difference, but the record does not say which is current.
What to Look For
Height, first. In its note on the Offering Hall, the Agency describes the Oka Shrine Main Hall as tall-standing and says the Offering Hall was designed to be set against it. From the front, the long, low Offering Hall fills the view, and the steep gable of the Main Hall rises a full stage above it behind.
Then walk to the side. The ridge posts stand outside the wall line, single timbers running up to the ridge, and in profile you can see the gap between post and wall. The crossed finials and the row of seven billets also read more clearly at an angle than straight on.
Few people ever get a long look at an Ise sanctuary. Here, even from outside a fence, you can study one side by side.
Seeing It
The Main Hall stands inside the Tamagaki Fence and its interior is not open. Visitors view it from outside the fence. The fence has lozenge lattice between its posts, and the roof rises well above it, so the ridge posts and finials are often easier to make out from a few steps back.
The front is hidden behind the Offering Hall and the Norito Hall. To see the building whole, walk along the fence to either side and look from a rear angle. The shrine forest keeps the grounds shaded, so the roofline is easiest to follow in good daylight.
