This shelf, inside the Shugakuin Imperial Villa in Kyoto was named the “Shelf of Mist”, was made under the direction of Princess Umenomiya. It dates to roughly 1665. It was a major departure from austere standards of a tea viewing platform & has had influence on numerous works since. The room is extremely feminine, and almost decorative. I think I heard the guide say that the princess later become a nun after the death of her father Emperor Go-Mizunoo, but it could have been her sister, and my mis-translation.
