Thank you for uploading this nice video! :D I'm sorry to have missed the livestream. The names of the geiko and maiko in the video are: 0:30 Maiko Mameryu of Tama (duh!) 2:51 Geiko Yukako of Nishimura 4:05 Geiko Makiko of Nishimura 4:43 Geiko Mikako of Nishimura - she's actually Yukako's little sister by mentorship 7:49 Maiko Koeri of Hiroshimaya Also Mameryu's kanzashi is supposed to resemble fireworks, I think.
Mameryu is my favorite maiko. She has such distinct mature features that the geiko style will look gorgeous on her when she changes. I was able to make a beautiful shot of her smiling when she was qalking in gion street and fell in love.
They are real - these "beer" gardens allows for outsiders to have a small geisha/maiko face to face experience interactions that wouldn't normally happen.
