I've read about tourists who go to Kyoto to get made up to look like geisha or maiko. Over half a million a year according to Foreign correspondent, and mostly Japanese, based on some makeover houses lacking English language support.
Where and when is the best time to photograph fake geisha/maiko? Criteria include likelihood of finding such individuals, having a photogenic background, and being in a location where they're more likely to agree to be photographed. A time and place where real geisha don't frequent is also good, but this article indicates when the real ones are active.
