Lake Biwa
Kansai Region
Lake Biwa, located in Shiga Prefecture in Japan's Kansai region, is the country's largest freshwater lake and one of the world's oldest lakes, dating back over 4 million years. Its shape resembles the traditional Japanese stringed instrument called the biwa, which inspired its name. The lake covers an area of approximately 670 square kilometers and serves as a crucial water reservoir for cities such as Kyoto and Ōtsu, supporting the drinking water needs of about 15 million people. Lake Biwa's ecosystem is exceptionally diverse, harboring more than 1,000 species and subspecies, including numerous endemic fish and mollusks. The lake is also an important habitat for water birds, attracting around 5,000 annually. Historically, the Lake Biwa Canal played a vital role in revitalizing Kyoto's industry in the late 19th and early 20th centuries. Today, the lake is a popular recreational destination with beaches like Shiga and Ōmi-Maiko, the Mizunomori Water Botanical Garden, and the Lake Biwa Museum offering cultural and natural insights. However, the lake's biodiversity faces challenges from invasive species such as black bass and bluegill introduced in the 20th century.
