Born to a paper-seller in Okayama-city, Okayama-prefecture, as the eldest son he was expected to take over the family business, and after reading Wealth of Nations he developed an early interest in economics.^[1] After attending Okayama Prefectural Middle School and High School number 6, he enrolled in the economics department of Tokyo Imperial University Law School, but after one month he transferred to political science. He graduated after a gap year due to illness, but attended no seminars.

In 1918 he began working for Sumitomo Bank, believing he would be conducting research. The Rice riots of 1918, along with disillusionment with his work, caused him to move towards a socialist perspective and leave his job after only three months.^[2] After a stint in his parents’ home, the following February he entered the university's Ōhara Institute for Social Research. Beginning in 1920, he and Kuchida Tamizō were dispatched to Europe for two years to gather books and other materials, Kuruma in England and Kuchida in Germany, the results of which proved invaluable to the research institute. From 1923 he lectured for three years on the history of economics at Doshisha University, yet did not take part in the Japanese Capitalism Controversy.

The Ōhara Institute relocated from Osaka to Tokyo in 1936, and Kuruma moved to the capital to continue his research there. The increasing climate of repression did not prevent him from continuing to study Marx, and took an interest in forecasting the postwar economic situation using Marx's ideas on money and inflation. He maintained a system of note cards containing important passages of Marx's writings, which later helped him compile the Lexikon.^[3]

The air raids of May 1945 destroyed the Ōhara Institute for Social Research along with all the materials stored there. After the war, along with Institute Chief Takano Iwasaburō, Kuruma occupied himself with rebuilding, until in 1946 upon the recommendation of Ōuchi Hōye he agreed to move the Ōhara Institute to Hōsei University, becoming a professor of political economy, finally receiving his doctorate in 1960. At Hōsei he participated in monthly readings of Marx which included Kōzō Uno, with whom he formed something of a theoretical rivalry.^[4] In 1964 he retired as a professor emeritus.

In his later years he assembled researchers of marxian economics from Hōsei and Rikkyō Universities to compile an encyclopedic “Lexicon of Marxian Economics,” published in a bilingual German-Japanese edition as Marx-Lexikon zur Politischen-Ökonomie. He saw the first three volumes published before dying of lung cancer in 1982.

Among his other teaching positions he served as a professor at Aichi University and as a part-time lecturer on the history of political economy at Tokyo University, Hokkaido University, Gakushūin University, and others.

• At Dōshisha University there was reluctance to begin lectures in history of political economy.^[5] By a twist of fate he was invited to be head of economic history at Hōsei.
• Upon entering Hōsei University, the board of trustees petitioned for his additional assistance with the university, but when he replied that he had his hands full with problems at the Social Sciences Institute (Ouchi Hyōe's return to Tokyo University, Takano Iwasaburo's recruitment as president of NHK, a lack of assistants), he was told he should bring the Ōhara Institute to Hosei, and in fact the two were merged in 1949.^[6]
• When Ōuchi Hyōe reached retirement age and left Tokyo University, he received a large number of job solicitations, but the request of Kuruma with whom he had been friends for 30 years is considered to be a major factor in his choosing to go to Hōsei.^[7]
• In Marx-Lexikon zur Politischen-Ökonomie, Tomidzuka Ryōzō’s equilibrium accumulation trajectory theory is described and criticized. Tomidzuka responded with a counterargument, initiating a theoretical dispute between them.^[8]
