Ichinosaka River

Overview

The Ichinosaka River is a small Class-2 river of the Fushino River system flowing through the city center of Yamaguchi in Yamaguchi Prefecture. Though only about 5.3 kilometers long, it winds gently through the heart of the old castle town, lined with stone bridges and quiet waterside paths. In early summer it is celebrated as a spot to see Genji fireflies, making it a lovely place to begin a stroll through Yamaguchi.

History

Yamaguchi flourished from the Muromachi period, when the Ouchi clan built the town in imitation of Kyoto, and the Ichinosaka River served as a familiar stream running through that castle town. It has long been a part of daily life in the city, and thanks to continued care of its waterside environment it is now protected as a clear stream where fireflies dance.
