yosemune yane 寄棟屋根

Also abbreviated to yosemune 寄棟, also called yotsuyane 四つ屋根. A hipped roof. A roof that descends from the ridge on four sides of a rectangular building. Therefore, hip rafters *sumigi 隅木 descend from each end of the ridge to the corners. The length of the ridge influences the angles made when the hip rafter bisects the corners. If the corner is bisected so that two 45 degree angles are created, the term used is masumi 真隅. If the corner is bisected to form unequal angles, it is called furezumi 振隅 (see *sumigi-no-fure 隅木の振). When hip roofs were constructed over square buildings and occasionally over buildings where the depth was greater than the length, the length of the ridge was adjusted so that the exposed part of the hip rafter can bisect the corner at 45 degree. The structural members, used to make a hip roof, are simpler if there is no hidden roof *noyane 野屋根. However, a much larger roof with sharper incline can be achieved if the building includes the hidden roof structure. Examples: Tōshōdaiji *Kondō 唐招提寺金堂 (8th century) in Nara; Daizenji Hondō 大善寺本堂 (1286) in Yamanashi Prefecture.
