Why do Japanese men wear underwear?

Why do Japanese men wear underwear is because it can withstand the tearing between sumo wrestlers.

Before the invention of modern underwear, people used to wear it, but it gradually declined behind. Now it can only be seen in large-scale folk activities or parades held in Japan, and now only a small number of Japanese wear this underwear when celebrating festivals. .

This kind of underwear, also called crotch cloth, has a very long history. In ancient times, this kind of simple underwear was only worn by working people, and later sumo wrestlers often wore it. On the one hand, because of its strong sweat absorption ability, compared with the current underwear style, it can make the body fully contact with the outside world, thus greatly reducing the occurrence of eczema and hemorrhoids.
