Also called honsumigawara 本隅瓦; sumi tomoegawara 隅巴瓦. A half-round, corner, eave-end, pendant tile; also called a half-round, corner, eave-end, hip tile. A type of tile used at the corner eave-ends of a hipped roof *yosemune yane 寄棟屋根 or hip-and-gable roof *irimoya yane 入母屋根. The half-round pendant tile nokisaki marugawara 軒先丸瓦 also called sumidomoe is placed at the front end of the corner. This name is derived from the wide use of the comma pattern *tomoemon 巴文 that decorated the pendant *gatō 瓦当 from the end of the 12th century onward.
Until the end of the 10th century, there was no hidden roof structure noyane kōzō 野屋根構造, so it was easy to employ ordinary *nokimarugawara 軒丸瓦 at the corner eave-ends. After the hidden roof came into use, the corner curved sharply upward, necessitating a special corner eave-end tile. However, due to the variation in the degree of curvature, the curvature on the upper part of the barrel *dō 胴 and the underside of the tile also varied.
