|(n) traditional underclothing|
Juban (襦袢, "underclothing") is a term that refers to several types of traditional undergarments worn by both men and women under traditional Japanese clothing.
Types of juban
A nagajuban (長襦袢, long juban) is a kimono-like underrobe. Constructed similarly to a kimono, a nagajuban is the layer worn immediately beneath the kimono. It is approximately ankle-length and has kimono-like sleeves. The collar and sleeves of a nagajuban are visible (in the case of the sleeves, occasionally visible) when wearing a kimono, and must therefore be appropriate to the season, occasion, and type of kimono worn.
The nagajuban provides warmth and protects the kimono from being soiled by having direct contact with the skin. A third layer, a hadajuban (see below) serves the same purpose for the nagajuban.
A hadajuban (肌襦袢) is so called because it directly touches the skin. It is worn under a nagajuban to prevent the latter garment from touching the body and being damaged or soiled by direct contact with the skin. Because hadajuban are in direct contact with the skin, they are usually made of breathable fabric. Hadajuban often have narrow sleeves rather than kimono-style sleeves. The collar and sleeves of a hadajuban are not visible when wearing a kimono.
A hanjuban (半襦袢, half juban) is shorter than a nagajuban, typically a little longer than waist length. They may be worn instead of a nagajuban in warmer seasons, or with a susoyoke (slip), suteteko or other lower garment as a kind of two-piece nagajuban. The collar and sleeves of a hanjuban are visible (in the case of the sleeves, occasionally visible) when wearing a kimono, and must therefore be appropriate to the season, occasion, and type of kimono worn.
