It's a Maiko (apprentice Geisha) with the kanzashi representing December. Their kanzashi(hair ornaments) changes from month to month to represent the changing seasons.
The two banners on the kanzashi have two signatures of their favourite kabuki actors
The black signature being the male actor
the red is the onnagata (male playing female)
Her kanzashi dangles with good luck charms and good fortune. When they walk with this ornament in their hair it makes a jingle noise from the bells attatched to it.
Maiko always use their real hair- these days girls dress up as maiko known as "henshin" they usually stop and pose for cameras and wear wigs- with an extremely tacky outfit. it's easy to spot them.
Real maiko and geiko(geisha) never stop to pose- unless it's a festival, special event, or you are just lucky.
No they aren't prostitutes- against what movies and people 'assume'
