The name "Busan" originally meant Busan area located on the right bank of Guichuan and belonging to a part of Nishikyo District, Kyoto City, while the area on the other side of the river and belonging to the Yukyo District was called Saitano, but many sightseeing guide materials in recent years have been generalized. The surrounding area on both sides of the river, which will be centered on the cross-Yueqiao in Guichuan, is called Lushan.
