{{nihongo|Lake Hamana|{{linktext|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.

Data

The lake has an area of 65.0 km2 and holds 0.35 km3 of water. Its circumference is 114 km. At its deepest point, the water is 16.6 m deep. The surface is at sea level.

History

In ancient times, Lake Hamana was a freshwater lake. However, the 1498 Meiō Nankaidō earthquake altered the topography of the area and connected the lake to the ocean. As a result, the water in the lake is now brackish.{{cn|date=May 2025}}

At the end of World War II two experimental Type 4 Chi-To tanks were dumped into the lake to avoid capture by Occupation forces. One was recovered by the US Army, but the other was left in the lake. In 2013, unsuccessful efforts were made to locate the remaining tank.Takagi, Shogo [http://www.japantimes.co.jp/news/2013/04/17/national/lake-hamana-searched-for-wwii-sunken-tank/ Lake Hamana searched for WWII sunken tank April 17, 2013] The Japan Times Retrieved April 3, 2016
