This type of swimwear began to appear in Japanese schools around the 1980s. As well as the old type, this swimsuit can be dark blue, violet, black or white. It's a one-piece swimsuit, which is most common in modern Japanese schools. In contrast to the previous type, it can have both a closed and an open back. It may also contain a tag with the name of the girl. This kind of swimsuit is commonly worn by high school students, but this is not necessarily so.
