Lake Hamana (浜名湖, Hamana-ko) is a brackish lagoon in Shizuoka Prefecture, Japan. Formerly a true lake, it is now connected to the Pacific Ocean by a channel. As an internal body of water, it is considered Japan's tenth-largest lake (by area). It spans the boundaries of the cities of Hamamatsu and Kosai.
