Guide
Biwako Sosui is a historic waterway constructed during the Meiji era to transport water from Otsu City in Shiga Prefecture to Kyoto City. It consists of the First Sosui (completed in 1890) and the Second Sosui (completed in 1912). This waterway has served multiple vital roles, including water supply, hydroelectric power generation, agricultural irrigation, industrial water use, and even water-based transportation. Today, it is a popular destination for walkers seeking beautiful natural scenery and historical architecture.
Built to modernize Kyoto during the Meiji era, the project was a cornerstone of regional development. The First Sosui was completed in 1890, followed by the Second Sosui in 1912. This project did more than just secure water; it contributed significantly to industrial growth through electricity supply. Notably, the Keage Power Station was one of Japan's first commercial hydroelectric plants, playing a crucial role in Kyoto's modernization. The area also featured an "incline" (a sloping railway) used to transport boats, facilitating water-based logistics. Due to this profound history, the site is recognized as a National Historic Site and a part of Japan Heritage.
Various historical remains line the Biwako Sosui. In the Otsu area, you can find the intake point of the First Sosui, where water enters from Lake Biwa. The intake for the Second Sosui features traditional plaques that add a touch of historical elegance. In the Keage area, parts of the incline equipment used for transporting boats are preserved, showcasing the water transport technology of the era. Furthermore, the path along the canal near the famous Philosopher's Path offers ever-changing natural beauty depending on the season.
Biwako Sosui offers a different face in every season. In spring, the area is adorned with blooming cherry blossoms; in summer, lush greenery frames the water; in autumn, vibrant fall foliage reflects beautifully on the surface; and in winter, a quiet, serene snowscape can be found. Visitors can enjoy a relaxing walk via the "Sosui Sanpo" paths, experiencing the shifting light and water flow at different times of the day. Special light-up events during certain seasons also create a magical atmosphere.
You can enjoy walking along the well-maintained "Sosui Sanpo" paths. There are three main routes: the Otsu-Kamogawa Course, the Kamogawa Canal Course, and the Sosui Line Course, each offering different distances and views. For a unique perspective, you can take a sightseeing boat ride on the Biwako Sosui Canal to view the scenery from the water's surface. It is a wonderful way to contemplate the history of industrial heritage and the technology of the past while walking through nature.
The Biwako Sosui stretches from the Otsu area in Shiga Prefecture through the Yamashina, Keage, and Okazaki areas of Kyoto. The surrounding area is rich with cultural spots, including Murin-an, Heian Jingu Shrine's garden, Kyoto University, and the various gardens of Higashiyama. As you travel from Otsu toward Kyoto, you can witness the harmony between urban development and the natural landscape.
Comfortable walking shoes are highly recommended. While many paths are well-maintained, some sections may have slight inclines or uneven surfaces. Please dress appropriately for walking. When visiting nearby facilities or enjoying the scenery, please respect the local environment and maintain a quiet, respectful presence.
