Tatsuji Miyoshi(三好達治Miyoshi Tatsuji, 23 August 1900 – 5 April 1964) was a Japanese poet, literary critic, and literary editor active during the Showa period of Japan. He is known for his rather lengthy free verse poetry, which often portray loneliness and isolation as part of contemporary life, but which are written in a complex, highly literary style reminiscent of classical Japanese poetry.
