A zigzag pattern which forms a decorative band resembling a series of lozenge shapes. It was used on the built-up ridges of many structures from at least the 17th century onward. It may appear alone or as one of several decorative bands ornamenting a massive, built up ridge *ōmune 大棟. See *kudarimune 降棟, *sumikudarimune 隅降棟, *chigomune 稚児棟.
Also nakafutobishi 中太菱. A variation of a diamond pattern called *hishimon 菱文 which consists of a diamond shape with smaller diamonds attached top and bottom. Used in the arrangement of muntins *kumiko 組子 in architectural fittings, and also in Japanese fabric designs. It was particularly popular in the Momoyama period for *tsujigahanazome 辻が花染 on *kosode 小袖, and for noh costumes *nōshōzoku 能装束. Variations include: tonbo-ni-matsukawabishi 蜻蛉に松皮菱 (dragonfly and lozenge), nijū matsukawa 二重松皮 (double lozenge), and ōmatsukawa 大松皮 (large lozenge).
