In the initial stages of the Occupation, the Allied Forces in Japan consisted of 400,000 American soldiers and 40,000 soldiers belonging to the British Commonwealth, including those from Australia, but by the breakout of the Korean War, the total had dwindled to 125,000 soldiers, less than a third of the original number. At its peak, the number of prostitutes attending to these soldiers rose to 500,000.[10] Japanese prostitutes that solicited foreign soldiers were commonly known aspanpan girls. Some of these panpan were given the title 'only' or 'only-one.' These 'only' girls had a specific soldier as their customer, unlike the sidewalk prostitutes ('butterflies') who did not have a specific clientele.
