Chapter 1: Understanding Japanese Black Formal Wear

The Two Garments Under One Name

The term "Japanese black formal wear" in English most often refers to a black kimono with family crests, but in practice it covers two distinct garments that share the same color, same cresting rules, and same general silhouette. The first is kuromontsuki (literally "black crested"), which is a solid black silk kimono decorated with one, three, or five family crests. The second is montsuki (crested kimono), which is a crested kimono that is not black - usually dark gray, deep indigo, or brown.

This handbook treats the two as one category because their construction standards, grading criteria, and care requirements are identical; the only meaningful difference is color and the formality ceiling that comes with it.

In the Japanese garment trade, kuromontsuki and montsuki are also called tomesode in the women's system, though that term technically refers to a woman's formal kimono irrespective of color.
