This is the poster for the two days gala performance "Hyakkaryouran" to celebrate Kazuo's centenary. Some 20 choreographers and dancers from all over the world gathered and offered each 10 minutes piece to Kazuo. On both day, Kazuo on his wheelchair appeared on stage with Yoshito during the curtain call. The photo used was taken by Yoshihiko Ueda in 1999. It was designed by Ryohei Hashimoto. There exist a full video recording and a program which bears texts by Eugenia Casini Ropa, a professor of Bologna University and Nobuo Tsuji, an art historian, the photographs by Eikoh Hosoe and short remarks by all the performers.
