It is called Yoshino River (吉野川, Yoshinogawa) in Nara.

The rainy season helped to create an Alluvial plain.

The JR West Wakayama Line partly runs in parallel with the river.

It was an area where the Koyasan, Kokawa and Mitsui temples were strong; centralized rule was impossible, until Nobunaga Oda suppressed the Saika Ikki.

The novelist Sawako Ariyoshi titled one of her books after the river.
