Also called *keshōyaneura 化粧屋根裏. The underside of a timber roof, commonly called an open ceiling or open-beamed ceiling, whereby the sheathing beams and rafters are visible and have been planed *keshō-ita 化粧板. In the early centuries, open-beamed ceilings were painted red. Example: Shin'yakushiji Hondō 新薬師寺本堂 (8th century), Nara. If a double roof system, with a hidden roof *noyane 野屋根, and ceiling *tenjō 天井, is used, the ceiling may follow a similar structural system with sheathing and a second set of rafters that are visible. This ceiling, although following the general characteristics of the hidden roof structure, is set considerably lower and has a more gentle pitch. It is believed that installed ceilings or hidden roofs were not used until late in the 10th century. When a hidden roof was placed only over the aisles *hisashi 廂, in the large reconstructed lecture hall *Daikōdō 大講堂 (990) at Hōryūji 法隆寺. A building in the pure daibutsu style *daibutsuyō 大仏様 does not have an installed ceiling or a hidden roof. Example: Jōdoji *Jōdodō 浄土寺浄土堂 (1193), Hyōgo Prefecture. After the 10th century, ceilings were often installed in temple buildings, but the worship hall *gejin 外陣, or the aisles *hisashi 廂 and *mokoshi 裳階, surrounding the core of a temple building were very often 1-bay deep and left open to the ceiling. In the case of pent roofs, the open-beamed ceiling is only the extension of the roof. Example: Jōdoji Hachiman Jinja Haiden 浄土寺八幡神社拝殿 (14th century), Hyōgo Prefecture, which has open-beams shaped like the underside of a hipped roof *yosemune yane 寄棟屋根; Daizenji Hondō 大善寺本堂 (1286), Yamanashi Prefecture.
