The Yasu River (野洲川, Yasu-gawa) is located in Shiga Prefecture, Japan; it is the largest river to flow into Lake Biwa. It rises from Mount Gozaisho and flows through Kōka, Konan, Rittō, Moriyama and Yasu. It forked at the lower reaches and made a delta region, but they were combined in 1979.

History[edit]

The Tōkaidō, one of the Edo Five Routes which connected east and west Japan during the Edo period, paralleled the river. Post towns along the river included Tsuchiyama-juku, Minakuchi-juku and Ishibe-juku. The Yasu River also crossed the Nakasendō, another one of the Edo Five Routes, separating Moriyama-juku and Musa-juku.
