Kataginu (top part of the kamishimo, a two piece samurai uniform worn over a kimono)
Probably kuzu (translated variously as arrowroot and kudzu) and cotton
Kudzu wefts, cotton warps; probably dyed with indigo and sumi; crests stenciled and hand painted with sumi

Kuzufu (kudzu cloth) was often used to make summer kamishimo. Its natural stiffness and quiet luster make it well adapted as a material for formalwear. Kamishimo are given an extra degree of strength at the seams with inserts, often made of whale bone or bamboo, both of which are flexible enough to bend without breaking. Traditionally, the sasarindo (bamboo and gentian) mon is associated with the Minamoto clan.
