Is kimono a Japanese costume?

Kimono is the national costume of Japan, which is developed from the Han costumes in China. During the Three Kingdoms period, Japanese women wore almost the same clothes, but they didn't have backpacks behind their waists, so they were called "five clothes" and "Tang clothes" in Wu Dong. Kimono is the name of Wufu in the west, and now the Japanese have accepted this name, but many shops selling kimonos still write "Wufu".
