This study aims at considering on Japanese postmodern dance, by researching Hijikata Tatsumi’s Ankoku Butoh, Dance of Darkness, which is known for most famous avant-garde dance of 1950s in Japan. Hijikata’s Butoh, started with Kinjiki in 1959, was an entirely new dance form having different qualities of expression from the other dances such as classic ballet and modern dance at that time of Japan. Mostly showing the experimental attempt on the stage by ordinary movement from the late 1950s to the early 1960s, Hijikata changed his performing style from his work in 1968, Hijikata Tatsumi and Japanese – Rebellion of Body. That means that Hijikata tried to make his own movement method. This study focuses on ‘Butoh notation’ as the principal reason of changing movement style of Butoh. By analyzing the existence of Butoh notations and contents of them, the research would figure out the actual relation between notation and creation of a new style.
