Hakama are a type of traditional Japanese clothing. They were originally worn only by men, but today they are worn by both sexes. Hakama are tied at the waist and fall approximately to the ankles. Hakama are worn over a kimono (hakamashita)[citation needed].

There are two types of hakama, divided umanori (literally horse-riding hakama) and undivided andonbakama (lit., lantern hakama). The umanoritype have divided legs, similar to trousers. Both these types appear similar. A "mountain" or "field" type of umanorihakama was traditionally worn by field or forest workers. They are looser in the waist and narrower in the leg.

Hakama are secured by four straps (himo); two longer himo attached on either side of the front of the garment, and two shorter himo attached on either side of the rear. The rear of the garment has a rigid trapezoidal section, called a koshi-ita. Below that on the inside is a hakama-dome (袴止め)[citation needed] (a spoon-shaped component sometimes referred to as a hera) which is tucked into the obi or himo at the rear, and helps to keep the hakama in place.

Hakama have seven deep pleats, two on the back and five on the front. The pleats are said to represent the seven virtues of bushido, considered essential to the samurai way. Although they appear balanced, the arrangement of the front pleats, (three to the right, two to the left) is asymmetrical, and as such is an example of asymmetry in Japanese aesthetics.

Men's hakama

The most formal type of men's hakama are made of stiff, striped silk, usually black and white, or black and navy blue. These are worn with black montsuki kimono (kimono with one, three, or five family coats of arms on the back, chest, and shoulders), white tabi (divided-toe socks), white nagajuban (under-kimono) and various types of footwear. In cooler weather, a montsukihaori (long jacket) with a white haori-himo (haori-fastener) completes the outfit.

Hakama can be worn with any type of kimono except yukata (light cotton summer kimono generally worn for relaxing, for sleeping, or at festivals or summer outings). While striped hakama are usually worn with formal kimono, stripes in colours other than black, grey and white may be worn with less formal wear. Solid and graduated colours are also common.

While hakama used to be a required part of men's wear, nowadays typical Japanese men usually wear hakama only on extremely formal occasions and at tea ceremonies, weddings, and funerals. Hakama are also regularly worn by practitioners of a variety of martial arts, such as kendo, iaido, taido, aikido, ryu-te, and kyūdō. Sumo wrestlers, who do not wear hakama in the context of their sport, are, however, required to wear traditional Japanese dress whenever they appear in public. As hakama are one of the most important parts of traditional male formal dress, sumo wrestlers are often seen wearing hakama when attending appropriately formal functions.

In addition to martial artists, hakama are also part of the every-day wear of Shinto kannushi, priests who maintain and perform services at shrines.

An Edo-era kamishimo ensemble.

Hakama traditionally formed part of a complete outfit called a kamishimo (上下 or 裃). Worn by samurai and courtiers during the Edo period, the outfit included a formal kimono, hakama, and a sleeveless jacket with exaggerated shoulders called a kataginu (pictured).

Samurai visiting the shōgun and other high-ranking daimyo at court were sometimes required to wear very long hakama called naga-bakama (long hakama). These resemble normal hakama in every way except their remarkable length in both the back and front, forming a train one or two feet long and impeding the ability to walk normally, thus helping to prevent a surprise attack or assassination attempt (see image here). Naga-bakamaare now only worn particularly in noh plays (including kyōgen), Kabuki plays and Shinto rituals.

Karusan-bakama

Some hakama during the Sengoku period had the hems made narrower than the body in imitation of the ballooning trousers worn by the Portuguese. This style carried on into the Edo period and became called karusan-bakama. In addition to the taper, they had a secured band of cloth—looking rather like a pants cuff—sewn around each leg’s hem, so the ballooning fabric would not open out like regular hakama.

Sashinukihakama

Sashinuki are a type of hakama that are meant to be worn blousing over the leg and exposing the foot. To accomplish this, they are somewhat longer than normal hakama, and a cord is run through the hem and drawn tight, creating a "ballooning" effect . To allow for the body required, more formal sashinuki were six-panel hakama rather than four panels. Technically, this cord around the ankle makes sashinuki a type of kukuri- (tied) hakama. The earliest form of sashinuki were cut like normal hakama (albeit a bit longer) and have a cord running through the hem of each leg. These cords were pulled tight and tied off at the ankle. This was the form commonly worn during the Heian period. Sashinuki were worn by court nobles with various types of leisure or semi-formal wear.

Women's hakama

Women's hakama differ from men's in a variety of ways, most notably fabric design and method of tying.

Hakama also wears in graduation day.

While men's hakama can be worn on both formal and informal occasions, except as part of martial arts wear, women rarely wear hakama except at graduation ceremonies and for traditional Japanese sports such as kyudo, some branches of aikido and kendo.[1] Only very rarely are hakama worn by women at tea ceremony. The image of women in kimono and hakama are culturally associated with school teachers. Just as university professors in Western countries don their academic caps and gowns when their students graduate, many female school teachers in Japan attend annual graduation ceremonies in traditional kimono with hakama.

The most iconic image of women in hakama is the miko or shrine maidens who assist in maintenance and ceremonies. A miko's uniform consists of a plain white kimono with a bright red hakama, sometimes a red naga-bakama during formal ceremonies.

While formal men's hakama are made of striped fabric, women's formal hakama are either a solid color or dyed with gradating hues. Hakama for young women are sometimes sparsely decorated with embroidered flowers like sakura. Women typically wear hakama just below the bust line, while men wear them at the waist.
