For several types of occasions pants known as hakama are worn on top of kimono. Pleated and resembling a skirt, hakama have a large slit running down the sides and are secured with four straps.
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 (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. There are many ways for men to tie hakama. First, the obi is tied in a special knot (an "under-hakama knot") at the rear. Starting with the front, the ties are brought around the waist and crossed over the top of the knot of the obi. The ties are brought to the front and crossed below the waist, then tied at the back, under the knot of the obi. The hakama-dome is then tucked behind the obi, the koshi-ita is adjusted, and the rear ties brought to the front and tied in a variety of ways. The most formal method results in a knot that resembles two bow-ties in a cross shape. For Women the method of tying the ties is also different, with women's hakama being tied in a simpler knot or a bow. As with men's hakama, the front ties are first brought to the back, then to the front, then tied at the back in a knot. Then the back himo are brought around to the front. At this point, they may be tied with a bow at the left hip, just in front of the opening, with the ends of the ties at equal lengths. For more secure fastening, the ties may be wrapped once at center front, then tied inside at the back.
