Another conception suggests that the word "fundoshi" originates from "Hun-t-os" (pronounced as "funtos") that is a Koreanized word of Chinese "kon-i" (literally, "fundoshi wear"), as Japanese language had primitively no word including a pronunciation of "n."
元来日本語には「ん」という発音の言葉がなかったことから、漢語の「褌衣」を韓国語化した「Hun-t-os,（フントス）」からくるという説もある。
