Noyane (野屋根) is hidden roof, used widely in Buddhist temples and Shinto shrines. It is composed of a true roof that is visible on top and a second roof below that is only visible when under the eaves, giving it its name. It has its own support system with hidden rafters that support the exposed upper roof.

— History

Noyane were invented during the Heian period. The earliest example of this roof style is Houryuuji Daikoudou in Nara. The roof is built over the hisashi surrounding the moya.

From the 12th century onwards, it became common to build noyane over the whole building.
