The point of departure for this work was the traditional object “Shishiodoshi” long inherited in Japan. The Shishiodoshi is a water-filled bamboo tube, which clacks against a stone when emptied; a device to frighten away birds from gardens. It reminds us of the serene scenery of Japanese gardens and clear spring water. For this installation, I made two kinds of Shishiodoshi. One is made of bamboo as the traditional material, and the other is made of grey water pipes. One symbolises a clean water and nature, while the other reminds us of dirty water. I made this work in response to the nuclear power plant disaster in Fukushima.
