Kiyoshi Inoue (井上 清 Inoue Kiyoshi?, December 19, 1913 - November 23, 2001) was a Japanese academic, historian, author and professor emeritus of the Kyoto University. He was considered a specialist in modern Japanese history. He was also known as a "progressive historian" and a "Marxist historian."
In 1954, Inoue joined the faculty of the University of Kyoto as an Associate Professor at the Institute of Humanities. In 1961, he was named a professor. He continued as a member of the Kyoto faculty until his retirement in 1977.
In his early career, Inoue established himself as a Marxist historian, publishing works on such subjects as the emperor system of Japan and buraku, and supported activism by Japanese far-left revolutionary groups.
In his later years, Inoue worked to expand the number of academic exchanges between Japan and China, and led a movement seeking solidarity with Asian nations. He ardently supported the Cultural Revolution in China and vocally criticized the Japanese Communist Party for taking a negative stance on the revolution, and as a result, was expelled from the party in 1967. He also published works on the subject of the Senkaku Islands dispute that sided with the Chinese claim.
Inoue received an honorary degree from the Chinese Academy of Social Sciences in 1997.
Inoue had published a book criticizing the Emperor system; and he continued to be critical of the Japanese emperor throughout his life. In a range of topics, his work was often viewed as controversial due to his active protests and lawsuits against the Japanese government. During the Japanese students riots in 1969, Professor Inoue openly supported the students who were demanding the scrapping of the U.S.-Japan Security Treaty.
