Specialty. Raku ware tea bowl, black, one of the seven types of non-kou. According to Kanamori Tokusui, the name comes from the triangular shape of the bowl, which makes the chidori drawn by Korin look like triangles. It is thinly made and has a slightly held mouth rim. The body has a pattern like the footprint of a plover in yellow glaze under a general black glaze, and a raku seal is clearly visible on the bottom. It was originally owned by Hirase Roka, a chikusa-ya in Osaka, and was sold to Fujita Ashian for 16,000 yen in 1903 (Meiji 36) when the family sold it to him. Incidentally, this is the first tea bowl that sold for more than 10,000 yen after the Meiji Restoration. It is now in the collection of the Fujita Museum of Art.
