Early Life and Academic Foundations
Born in 1912 in Nagoya, Japan, Nobuo Tsuru was the son of Nobuo Tsuru, an industrial engineer and former president of Tōhō Gas Co., Ltd. His early adulthood was marked by political awakening; while studying at the Eighth Higher School (now part of Nagoya University), he became a student leader in the "Anti-Imperialist Leagues" between 1929 and 1930, opposing the Japanese military's aggression toward China.
These activities led to several months of imprisonment and expulsion from his school. Barred from entering imperial universities in Japan, Tsuru sought tertiary education in the United States. He began his studies at Lawrence College in Appleton, Wisconsin, before transferring to Harvard University. He graduated with Honours in 1935 and was the sole member of his class to proceed to graduate school, where he studied alongside the renowned economist Paul Samuelson.
Tsuru completed his Ph.D. at Harvard in 1940 with a dissertation titled "Development of capitalism & business cycles in Japan, 1868-1897," subsequently serving as a lecturer at the university.

Wartime Challenges and Public Service
The outbreak of World War II and the Pacific War prompted Tsuru to resign from Harvard in 1942 and return to Japan. Through the influence of Shigemitsu Mamoru and his wife's uncle, Kōichi Kido, he secured a position as a commissioned staff member at the Ministry of Foreign Affairs. In 1943, he expanded his research as a commissioned researcher at the East Asian Economic Research Institute of the Tokyo University of Commerce (now Hitotsubashi University).
Tsuru's tenure was not without conflict. In June 1944, Prime Minister Hideki Tōjō dismissed him as a means of pressuring Kōichi Kido during a political dispute. This led to Tsuru's conscription into the Imperial Japanese Army. However, after intervention by Sadao Akamatsu, who argued that Tsuru was "irreplaceable," he was discharged after only three months of service.
Post-War Economic Reconstruction
Following the war, Tsuru played a critical role in rebuilding Japan's economy. He worked within the Survey and Statistics Division of the General Headquarters (GHQ) of the Allied Powers. By 1947, under the Katayama Cabinet, he was appointed Vice-Chairman of the Overall Coordination Committee of the Economic Stabilization Board, a role equivalent to a Vice-Minister.
During this period, he authored the landmark "Report on the Actual State of the Economy," the first post-war economic white paper, which provided a foundational analysis of Japan's financial health. In 1948, he joined the faculty of the Tokyo University of Commerce and began hosting the "Suit Seminar" for working professionals at his home.
Amidst the global tension of the Cold War and the rise of McCarthyism (the "Red Scare"), Tsuru demonstrated transparency by publicly confessing to his Communist affiliations during his student years in the United States.
Academic Leadership and Environmental Advocacy
Tsuru's academic career was defined by his long association with Hitotsubashi University. In 1949, he became the first director of the Hitotsubashi University Institute of Economic Research. His influence extended globally through visiting professorships at Harvard University (1956) and Yale University (1960).
Beyond pure economics, Tsuru recognized the growing threat of industrial pollution. In 1963, he co-founded the Pollution Research Committee with Tokue Shibata and Ken'ichi Miyamoto. This initiative eventually evolved into the Japan Environmental Council, and in 1971, he launched the academic journal Pollution Research (Kōgai Kenkyū).

The Presidency of Hitotsubashi University
In 1972, during a period of intense campus unrest that had left the presidency vacant for three years, Tsuru was appointed President of Hitotsubashi University. He was the first person to hold the office who was not an alumnus of the institution. Despite his qualifications, he faced criticism for his outsider status and retired in 1975 as an Emeritus Professor.
Later Years and Legacy
In his later years, Tsuru served as an Editorial Advisor for the Asahi Shimbun (1975–1985) and became a professor at Meiji Gakuin University in 1986, where he helped establish the Faculty of International Studies. He resigned from the university in 1990 following internal conflicts.
Nobuo Tsuru passed away on February 5, 2006, at the age of 93 due to prostate cancer. His memorial at Josuikai Hall was attended by over 500 people, including prominent figures such as former Bank of Japan Governor Masaru Hayami and Emeritus Professor Mitsuharu Itoh.
