Flowing through the heart of Chiba Prefecture, the Yōrō River gives life to the stunning Yōrō-Keikoku Valley. The Yōrō River, a designated Class 2 River under the Rivers Act of 1906, stretches an impressive 73.4 kilometers. Its basin covers an area of 260 square kilometers. The Yōrō River begins its journey near Mount Kiyosumi. It gracefully flows through the towns of Ōtaki and Ichihara. This river is more than just a waterway. It’s a key to understanding the history and landscape of this region. The Yōrō River carves its way through the Bōsō Hill Range, eventually reaching Tokyo Bay in Ichihara’s Goi and Iwazaki districts. Here, at the river’s mouth, land reclamation has played a crucial role in the development of the Keiyō Industrial Zone. The Yōrō River offers a diverse landscape. The upper reaches boast the dramatic Yōrō Ravine and the breathtaking Awamata Falls. Further along, the river converges with the Koshikiya, Heizō, and Uchida Rivers. The middle and lower sections of the Yōrō River tell a different story. Here, the fertile lands surrounding the river have been cultivated for rice production, shaping the local agriculture for generations. The Kominato Railway Line shadows the Yōrō River, offering convenient access to the natural wonders that dot its course. Whether it’s the tranquility of the mountains, the cascading beauty of waterfalls, or the soothing warmth of an onsen hot spring, the Yōrō River provides a path to unforgettable experiences.
