Why do Japanese boys like to wear white socks

Japan is an island country with few products. In ancient times, there was almost no dye in its native land. Because of its monsoon climate, there are almost no dyes in its plants. After the transformation, Japanese talents learned the extraction technology of dyes from China, and the extracted dyes were used in coats and hardly used in socks, because they were too precious. So the tradition of wearing white socks was formed.
