Overview
The use of tiled roofs, which was a symbol of continental culture and the advanced state of the central administration, spread during the Asuka and Nara period to Buddhist temples and regional administrative centers. The Ninomiya kilns are located on the slope of a hill within the precincts of the Ōminakami Shrine, which is the ninomiya (second shrine), of Sanuki Province. The kiln ruins were discovered in 1925. This kiln site was built from the late Heian period to the Kamakura period, and consists of the ruin of two kilns, one of which has an elliptical body and a firing port facing north. It is a noborigama climbing kiln with several vein-shaped fire grooves on the bottom and a mounting base on which roof tiles are placed. Flat tiles used at the eaves with arabesque patterns were excavated from the inside. The other kiln was is square, flat kiln, with the firing port facing northeast and a built-in base with several fire grooves. Eaves tiles, earthenware, and ink-stones have been excavated from the inside. The site is about 20 minutes by car from the JR Shikoku Yosan Line Takase Station.
