The British Commonwealth Occupation Force (BCOF) was the British Commonwealth taskforce consisting of Australian, British, Indian and New Zealand military forces in occupied Japan, from 1946 until the end of occupation in 1952.
At its peak, the BCOF committed about 40,000 personnel, that comprised 25% of the occupation force, which was equal to about a third of the number of US military personnel in Japan.
