Kimonos were heavily influenced by traditional Han Chinese clothing, known today as hanfu (漢服?, kanfuku in Japanese), through Japanese embassies to China which resulted in extensive Chinese culture adoptions by Japan, as early as the 5th century AD
Looks like a kind of Chinese costume. Very elegant.
