The East Asia Development Board, or Kōain (興亜院), was a cabinet level agency in the Empire of Japan that operated between 1938 and 1942. It was created on 18 November 1938 under the first Konoe administration to coordinate the government's China policy. It was initially designed to sponsor industrial and commercial development in China to boost support for Japanese rule in occupied territories. However, the agency was quickly usurped by the Imperial Japanese Army and became a tool for forced labour and enslavement in mines and war industries. It was absorbed into the Ministry of Greater East Asia in 1942.
