mitsumoya 三母屋
KEY WORD : architecture / general terms
Also called mitsumoya osame 三母屋納; mitsumoya-zukuri 三母屋造. The location or positioning of the base of a bargeboard. If the pitch *koubai 勾配, of a hip-and-gable roof *irimoya-zukuri 入母造, is divided into thirds, based on an imaginary straight line extending from ridge *munagi 棟木 to eave end *nokisaki 軒先, the base of the bargeboard *hafu 破風 is positioned one third the distance in from the eave ends. Divisions based on fifths are called itsutsumoya 五母屋. If the imaginary straight line from ridge to eave end is divided into five equal parts, the bottoms of the bargeboards are set one fifth of the distance in from the eave end. When the imaginary line is divided into seven spaces, it is called nanatsumoya 七母屋, nanatsumoya-zukuri 七母屋造 or mitsuhan moya 三半母屋. The divisions are not of equal size, however. The uppermost division, the seventh from the eave end, is half the length of the other divisions, and thus the end of the bargeboard terminates 3/14 of the distance in from the eave ends.
