A Muromachi Shrine Hall in Northern Shinano
The Takeminakatatomi no Mikoto Hikokamiwake Shrine Subsidiary Wakamiya Hachiman Shrine Main Hall (健御名方富命彦神別神社末社若宮八幡神社本殿) is a Muromachi-period single-bay Nagare-zukuri sanctuary in the grounds of Takeminakatatomi no Mikoto Hikokamiwake Shrine in Toyota, Iiyama City, Nagano Prefecture, which in 1952 was designated an Important Cultural Property.
The Nagano Association of Shinto Shrines lists the Wakamiya Hachiman shrine as a subsidiary shrine within the precinct, dedicated to Osazaki no Mikoto, better known as Emperor Nintoku. The parent shrine stands in the Goso area of the Ota district of Toyota.
The Agency for Cultural Affairs records the building as a single-bay nagare-zukuri hall roofed with tochi-buki, a shingle roof laid with boards thicker than the fine kokera shingles often seen on small shrines.
Two Views of Its Date
The date of the Wakamiya Hachiman Shrine Main Hall is not settled. The Agency for Cultural Affairs assigns it to the mid-Muromachi period, giving a range of 1393 to 1466.
Iiyama City, drawing on dismantling and reassembly work in 1973 and 1974 that found no sign of any earlier dismantling, presents as the accepted view that Ozaki Masashige built it between about 1469 and 1476. The city adds that Masashige retired to Tongenji, a temple he founded about 300 metres to the north, and may have raised Hachiman shrines around it.
The two ranges do not overlap, so both are given here.
Why It Is an Important Cultural Property
Iiyama City describes the Takeminakatatomi no Mikoto Hikokamiwake Shrine Subsidiary Wakamiya Hachiman Shrine Main Hall as unpainted timber in a pure Japanese style. The chamfering of the porch posts and boat-shaped bracket arms, the curve given to those long arms, the section of the door frame and the forms of the tie beams, rafters, bargeboards, gable pendants and beam-end covers all show Muromachi features.
Those details come together in a clean, restrained building, and the city notes that its good state of preservation down to small parts makes it a valuable survival for the northern Shinano region.
What to Look For
The hall is tiny. Iiyama City gives it as 186 centimetres wide and 141 centimetres deep, with a porch projecting 122 centimetres for an overall depth of 261 centimetres.
Start with the corners of the porch posts: the width of their chamfer and the curve of the slender bracket arms above are the features singled out as Muromachi work. From the side you can see the pendant hanging below the bargeboard and the covers on the beam ends.
Because the timber is left unpainted, the cut of each member reads clearly. At the eaves, look for the thickness of the tochi-buki boards.
