The Flag of Shiga Prefecture is the official symbol representing Japan’s Shiga Prefecture, located in the Kansai region on Honshu Island. Adopted in 1947, it consists of a white field with three red maple leaves arranged vertically at the hoist side and a stylized representation of Lake Biwa centrally placed. The three maple leaves signify the prefecture’s original districts, while the lake design embodies the importance of Japan’s largest freshwater lake to Shiga’s history and economy. The flag serves as an emblem of pride for Shiga citizens and is used in various official capacities, such as on government buildings and vehicles, as well as during special events and ceremonies.
