Tracing the History of Boat Transportation on the Kiso River (Middle Reaches)

Timber from the Kiso region was used to build historic structures such as Osaka Castle and Fushimi Castle. Trees grown in the mountains of Kiso were transported downstream by river, supplying towns in Owari and Mino and other areas beyond. It is also said that sacred trees used in the Ise Grand Shrine’s Shikinen Sengu, the ritual rebuilding of the shrine every 20 years, were assembled into rafts at the Nishikori timber rafting site in Yaotsu and sent down the Kiso River.

River transport developed to carry timber and other goods, but the river served a much greater purpose than simply moving cargo. Ports and ferry crossings were established along its banks, connecting people, goods, and information. Trade flourished, and each community developed its own distinctive culture. The Kiso River was a vital route linking forest resources with people’s daily lives and supporting the growth of the region.

Over time, the role of the Kiso River began to change. In the modern era, its water was harnessed to generate hydroelectric power, while its beautiful gorge scenery attracted visitors. In 1924, during the Taisho era, sightseeing boat services between Oowaki Port in Dota, Kani City, and Inuyama began operating on a larger scale. The river gradually became known not only as a route for transporting goods, but also as a place to enjoy the beauty of nature.

On this journey, we follow the Kiso River from Inuyama, exploring the gorges, cliffs, unusual rock formations, and traces of old ferry crossings shaped by the river. We also discover the history of river transport and the roads that once connected communities. In Yaotsu, we visit Nishikori, once an important timber rafting site, and Kurose Port, while learning about local festivals and the region’s brewing traditions.

Timber grown in the mountains traveled downstream, supporting people’s livelihoods and industries while helping towns grow and local cultures flourish. By exploring these historic places, we trace the story of the Kiso River basin and discover how nature and human life have shaped one another over time.
