Well like in America there are different types of styles.
To school they have their uniforms.
Some styles are decora, gothic lolita, Visual Kei, gyaru, ganguro. . . and many more.


Im not too sure either, but I do know that they wear kimonos and a summer kimonos (they have a special name) and pretty much anything\ casual clothes.

In summer festivals women wear Yukatas (Traditional Japanese dresses). Apart from that, they dress pretty much like anyone else in the world.

They traditionally wear kimonos.
But modern Japanese clothes are similar to clothes we wear in america.

There are also clothes from China, South Korea, Tawain, etc.
