Nameplates of Tama okiya in Gion Kobu by WATASHAJI - BLOG.
Every okiya has a bunch of nameplates with its active geiko and maiko nailed to the door. Sometimes it’s associated with so many geiko/maiko so it needs double plate just like Tama okiya. Above there are senior geiko, below - junior ones, jikata (musicians) and maiko.
A new nameplate is added during the misedashi (debut) ceremony and removed after hiki iwai - a ceremony of leaving the hanamachi, in simplier words, retirement.
What’s happening there? A lady in green kimono is removing maiko Mamechika’s nameplate. It means that Chika san has left Tama okiya and finished her career forever.
