fundoshi

Fundoshi is a traditional Japanese male undergarment, resembling a loincloth. It is made from a single length of cloth, usually cotton or hemp, and is worn by wrapping it around the hips, passing the fabric between the legs, and tying it with a knot at the waist. The front portion may cover or reveal the genitals depending on style.

Historically, fundoshi were common in the Edo period and earlier, worn by laborers and people of various classes. The garment’s length and the way it is tied create different fits; the knot can be placed at the front or back, giving variations in exposure and support. Modern variants exist that preserve the traditional wrap-and-tie method, sometimes with sewn edges or variations in fit.

During the 20th century, Western-style underwear largely replaced fundoshi as daily wear in Japan, but it remains associated with festivals and traditional performances. It is notably worn during Hadaka Matsuri, a naked festival in which participants wear fundoshi. It has also appeared in fashion and media as a cultural symbol of historic Japan.

Today, fundoshi are produced by specialty textile makers and retailers, and are sold as traditional garments, collectible items, or festival wear. They are not widely used as everyday underwear outside of cultural contexts.
