Main Hall of Oki Shrine, Subsidiary Shrine of Daiho Shrine

A Shrine Older Than the Shrine That Contains It

The main hall of Ōki Shrine (追来神社本殿), a subsidiary shrine standing inside the precinct of Daihō Shrine at Heso in Rittō City, Shiga Prefecture, was built in 1283 and designated an Important Cultural Property on 14 April 1906. The Agency for Cultural Affairs gives the reading as Ōki; local usage varies, and Ōki, Ōuki and Ofuki all appear in Japanese sources.

It is a small building. One bay across the front, roofed in cypress bark, with the front slope of the roof extended forward over the steps in the nagare-zukuri manner that became the standard form for Japanese shrine halls. Nothing about it announces itself, which is part of why the sequence of events here is easy to miss.

Daihō Shrine, the larger institution, dates its founding to the Taihō era, specifically to 701, when a plague is said to have moved the deities Susanoo and Inadahime to descend at Shinano-dō in the village of Kohirai and then to travel by way of Ryōzenji to Heso. What they arrived at was already sacred ground: the precinct of Ōki Shrine. The land deity was in residence first, and the shrine that would grow to serve fifty-odd parish villages was established around him. Ōki Shrine enshrines Tatamihiko no Mikoto and has also been known as Wakamiya Gongen; an old identification with the Ifuki Shrine listed in the tenth-century Engishiki register has been argued but not settled.

The date of construction is not deduced from style alone. A munafuda, a wooden ridge tag recording the raising of the frame in 1283, survives and is included in the designation as an attached item. It is currently deposited with the Rittō Museum of History.

What the 1906 Designation Recognised

The designation date is worth dwelling on. April 1906 places this hall in the earliest wave of national protection, under the Ancient Shrines and Temples Preservation Law of 1897, decades before most rural shrine architecture came under review. Buildings selected that early were selected because specialists at the time judged them structurally exceptional rather than locally beloved.

What made it exceptional is the combination of date and type. Ichigensha nagare-zukuri, the single-bay version of the flowing-roof hall, went on to become the commonest shrine plan in Japan; documented examples surviving from the Kamakura period are rare, and the Ōki hall is regularly described as the oldest extant example of the form and as the oldest shrine hall in Shiga Prefecture. Those rankings come from architectural surveys rather than from the Agency's database, which records only the date, the structure and the attached ridge tag.

Rittō sits in the old province of Ōmi, and Ōmi retains more designated medieval buildings than almost anywhere outside Kyoto and Nara. Within that concentration, a dated Kamakura shrine hall in a form that later became universal has a particular value: it shows the type at a point when it was still being worked out.

Restoration has left its marks. Dismantling and repair addressed serious deterioration, and later alterations around the front step and veranda remain visible; the kaerumata frog-leg struts on the outer portion were remade following the pattern of those on the moya, the core structure. The cypress-bark roof has been renewed in recent years. Reading the building means reading which parts are thirteenth century and which are conservation, and the seam is not hidden.

Daihō Shrine holds a second Important Cultural Property, a pair of wooden komainu guardian lions of the Kamakura period, kept at the Kyoto National Museum. An inscription on them reading Ifukiri Sōchū is one strand of the argument connecting Ōki Shrine to the Engishiki entry.

Seeing It

Come in from the west, over the stone bridge and under the torii. The approach doubles as the car park. Partway along on the left stands a four-legged gate with a roofed mud wall, given by the imperial court in the Kyōhō era; the five white stripes running along the wall mark that provenance, a convention reserved for buildings connected to the court.

Past the gate the ground opens into gravel. The worship hall sits in the middle, the inner gate behind it, and the main hall of Daihō Shrine stands within a fence beyond. Ōki Shrine is to the right and slightly forward of it. Balancing it on the left is Inadahime Shrine, a Rittō municipal property, so the two subsidiary halls face each other across the axis.

Look at the roof line first. The cypress bark is laid in courses so fine that the eave reads as a single soft edge, and the forward sweep over the steps is deeper than the proportions of the tiny body would predict. Then look at the struts under the eaves. The building rewards a slow circuit more than a photograph.

The grounds are open at all times and there is no fee. The hall stands outdoors and can be seen whenever the shrine is accessible; its interior is not open. Photography in the precinct is not restricted by any posted notice, though the usual courtesy applies during rites.

Getting here is easy in a way that visiting a Kamakura building rarely is. Rittō Station on the JR Biwako Line is about 500 metres to the southeast, ten minutes on foot, and the shrine fronts the old Nakasendō highway. The annual festival falls on 4 May; a sanyare dance was revived in the parish from 2016. Combining the visit with Rittō Museum of History, which holds roughly 2,000 documents deposited from the shrine, gives the building the context that a ten-minute stop cannot.
