Dazai more than once referred to the Seven Sages of the Bamboo Grove in his essays and letters. They were a group of seven hermits who respected Lao Zhuang (Taoism) and escaped from the secular world to enjoy a free life in the Weijin dynasty. The seven were Ruanji, Jikang, Santao, Liulin, Ruanxian, Xiangxiu, Wangrong. They are said to have always gathered in a bamboo grove to drink alcohol and converse. This paper will attempt to explain how Dazai thought of them and through what sources he formed his concept of them.
