Fan rafters. There are two arrangements: those that radiate from a center point on each side of the building; or those that are set parallel to each other until they near the corners of a building, where they are made to radiate toward the hip rafter *sumigi 隅木. The latter type of rafter arrangement is called sumi ōgidaruki 隅扇垂木, and is characteristic of the daibutsu style *daibutsuyō 大仏様. The former arrangement is characteristic of the Zen style *zenshūyō 禅宗様. Although radiating rafters became popular from the 14th-15th century, an excavation on the temple grounds at Shitennōji 四天王寺 in Osaka, by Dr. Asano Kiyoshi 浅野清 unearthed fragments of round radiating fan rafters from the Nara period, at the temple's site of the lecture hall *kōdō 講堂. Examples: in the daibutsu style, Jōdoji *Jōdodō 浄土寺浄土堂 (1192) in Hyōgo Prefecture; in the Zen style, Anrakuji *Hakkakutō 安楽寺八角塔 (Hakkaku Sanjū-no-tō 八角三重塔 ; 1339) in Nagano Prefecture.
