They are placed at the ends of a main ridge *ōmune 大棟, on corner ridges sumimune 隅棟, or on descending ridges *kudarimune 降棟. One is also placed on *chigomune 稚児棟, offspring ridge, the shorter and outer-end ridge when the corner ridge is divided in two by a long corner ridge *sumi kudarimune 隅降棟. Toribusuma have a decorative pendant tile *gatō 瓦当 at the front end. The upper surface has minimal to exaggerated curves.
