A linecloth which used to make Japanese traditional underwears for men. It was originally brought from China in history long ago, but now it becomes a part of Japanese culture, and most chinese don't know this already. Some Japanese men wear fundoshi for their summer festivals, and some of them wear it for swimming. It is very rare to see any males wearing fundoshi in Japan nowadays due to their westernlized society. However, there are still some Japanese who enjoy their own culture and wear fundoshi as their daily underwears. There are many kinds of fundoshis, such as roku-shaku fundoshi..etc. In some situation, fundoshi also refers to T-back underwears.
