Lake Biwa Museum

The Lake Biwa Museum in Shiga Prefecture, Japan, explores the relationship between the lake and people, focusing on the natural and cultural history of Lake Biwa — one of the world's few ancient lakes and Japan's largest freshwater lake. Exhibits cover geological history, human history, the lake's ecology and biodiversity, and its connection to daily life. The museum also features an aquarium, Discovery Room, outdoor exhibits, and active research programmes on Lake Biwa's unique ecosystem.
