Pine-bark diamond
松皮菱 matsukawa bishi

A large diamond with smaller diamonds above and below, like flaking pine bark; the pine's evergreen longevity makes it auspicious, good for New Year and celebrations.
Popular in the Momoyama and early Edo periods
A stepped diamond (also nakabuto-bishi) whose edges recall flaking pine bark. It was especially fashionable in the Momoyama period on tsujigahana-dyed kosode and noh costumes, and from at least the 17th century it decorated temple roof ridges and kumiko latticework. It also became a family crest and was used in samurai dress.
Common as a frame for other motifs on formal kimono and as a celebratory pattern.
