Japanese: Tobi trousers or Japanese: tobi pants are a type of baggy pants used as a common uniform of , construction workers in Japan who work on high places (such as scaffolding and skyscrapers).[1] The pants are baggy to a point below the knees, abruptly narrowing at the calves so as to be put into the footwear: high boots or Japanese: [[jika-tabi]] (Japanese: [[tabi]]-style boots).
According to a spokesperson for Japanese: [[Toraichi]]|italic=no, a major manufacturer of worker's clothes of this style, the style was developed from knickerbockers which were part of Japanese military uniform during World War II. The regular knickerbocker-style pants are called Japanese: "nikka zubon" (Japanese: "zubon" meaning "trousers" and Japanese: "nikka" or Japanese: "nikka-bokka", a Japanese: [[gairaigo]] transformation of the word "knickerbockers"). The excessively widened ones are called Japanese: chocho zubon.[2] This style has also entered popular fashion,[3] as evidenced by the emergence of Japanese: toramani ("Japanese: Toraichi|italic=no maniacs"), die-hard fans of Japanese: Toraichi|italic=no trousers.[1]
