The Kirizuma-zukuri style is one of Japanese traditional architectural styles, especially said of the styles of roofs. Japanese roofs are classified into any one of the three representative styles; Kirizuma (gable roof), Yosemune (hip roof) and Irimoya (hip-and-gable roof).

The ends of buildings with gable roofs have a triangular space (gable) made by the incline of the two sides of the roof. Seen from the gable side, the wall looks as if it was cut by the roof; hereby it is called Kirizuma, which literally means “a cut gable.”

The Kirizuma-zukuri style was a basic architectural style in ancient Japan. The gable roof was prized most highly during the Kofun period (3rd-6th centuries), when it was the symbol of the residences of powerful rulers. However, in the Nara period (710-794), when the Yosemune-zukuri style (with hip roof) was introduced from China, it was considered more sophisticated because extension of the roof was apparently recognized.

Later on, the Irimoya-zukuri style (with hip-and-gable roof) became most favored in the prestigious buildings such as palaces, noblemen’s residences and temples due to its combined features; the symbolic character of the Kirizuma style and the expansivity of the Yosemune style.
