Lisa says what Sayuki has accomplished is quite incredible. "[Tokyo] is one of the most hypermodern futuristic cities in the world, but she's existing in 17th-century Japan," she says. "It's pretty extraordinary that she's able to do that."

Sayuki says she's proud to bring a touch of the ancient art of geisha to the modern world. "I think it's a good thing for geisha to be more involved in the center of modern life and more visible to young Japanese women today."
