The 'Katsura River' (
Japanese: 桂川, ''Katsura-gawa'') is a continuation of two other rivers, the
Hozu River, a small, speedy river which begins in the mountains near
Kameoka and then slithers through the mountains separating Kameoka and
Kyoto, and the Oi River (大堰川, ''Ōi-gawa''; not to be confused with the
Oi River [大井川] in
Shizuoka), which emerges from those mountains and expands into a shallow, slow-flowing river until
Togetsukyo Bridge in
Arashiyama. From that point forward, the river is referred to as the Katsura River, and its flow continues for several kilometers until it joins the
Kamo River and
Uji River.
The Katsura River area features some of the oldest shrines in Kyoto and Japan, such as the
Matsuo Shrine, and, as a counterpoint to the channelled Kamo River, supports acres of agricultural area on its flood plain. It also is known for its summer supply of
Ayu and is a popular place for holding barbecues.
