Masachi Osawa

2.1. Early Life and Education

Masachi Osawa was born on October 15, 1958, in Matsumoto, Nagano Prefecture, Japan. For his early education, he attended Shinshu University Faculty of Education Affiliated Matsumoto Elementary School and Shinshu University Faculty of Education Affiliated Matsumoto Junior High School, followed by Nagano Prefectural Matsumoto Fukashi High School. He pursued his higher education at the University of Tokyo, graduating from the Faculty of Letters, Department of Sociology. In 1987, he completed the doctoral course at the University of Tokyo Graduate School of Sociology, and in 1990, he was awarded his Ph.D. in Sociology from the University of Tokyo. His doctoral thesis was titled 行為の代数学_{Koi no Daisugaku}^Japanese (The Algebra of Actions). During his doctoral studies, he was supervised by the prominent sociologist Munesuke Mita.

2.2. Academic Career

Osawa began his professional academic career in April 1987 as an assistant at the University of Tokyo Faculty of Letters, a position he held until 1990. Following this, he served as a lecturer and later an associate professor at Chiba University Faculty of Letters. In 1998, he joined Kyoto University Graduate School of Human and Environmental Studies as an associate professor, and by 2007, he was promoted to professor within the same department. He resigned from his professorship at Kyoto University on September 1, 2009. Since 2014, Osawa has continued to contribute to academia by delivering lectures at Waseda University Faculty of Letters, Arts and Sciences. In addition to his teaching roles, he has been the chief editor of the intellectual magazine THINKING「O」_{THINKING "O"}^Japanese since 2010.

3.1. Body Theory and Meaning Construction

Osawa is particularly known for his development of a distinctive "body theory" that explores how our life-world is constructed, with a specific focus on the processes that generate norms and meaning. He posits that all human activities are sustained by the coordination between more than two bodies, which can include physical objects. This coordination, which Osawa terms the "inter-bodily chain," forms the fundamental basis of our experiences. From his perspective, the interaction of these bodies collectively produces a "transcendental agency" that plays a crucial role in defining what is considered valid, invalid, appropriate, or inappropriate within a given social context.

3.2. Concepts of Societal Eras

Osawa has introduced influential concepts to characterize different periods of contemporary society. He labeled the period from 1970 to 1995 as the "Age of Virtuality," an era defined by the relativization of reality. Following this, he identified the period starting from 1995 onwards as the "Age of Impossibility." This subsequent era is characterized by a significant decline of totality in contemporary society, suggesting a fragmentation of overarching narratives and unified social structures.

3.3. Other Key Theories

Beyond his body theory and concepts of societal eras, Osawa has contributed other significant theoretical ideas. He has proposed the concept of the "mediafication of the body," which suggests a process by which the human body becomes increasingly mediated or "colonized" by media. He has also explored the idea of "thinking 'in Japanese'," engaging with the specific ways of thought embedded within the Japanese language and culture, particularly within the realm of Japanese literature education. Furthermore, Osawa has offered insights into how primatology has reshaped human self-perception, particularly on the 60th anniversary of primatology. His academic specializations include mathematical sociology and theoretical sociology, reflecting his rigorous and logical approach to analyzing social phenomena. He has been a notable contributor to influential Japanese postmodern journals such as 批評空間_Hihyōkūkan^Japanese (Critical Space), edited by Kojin Karatani and Akira Asada, and has also written essays for the Japanese arts and technology journal InterCommunication.

In 自由という牢獄_{Jiyū to Iu Rōgoku}^Japanese (The Prison of Freedom) and 〈自由〉の条件_{Jiyū no Jōken}^Japanese (The Conditions of Freedom), he explores the complexities of liberty in modern society. He also addresses the sociological understanding of justice and its implications for individuals facing difficulties in life, as seen in 「正義」を考える_{Seigi o Kangaeru}^Japanese (Thinking about "Justice"). These works collectively delve into the fundamental aspects of the human condition, seeking to define and understand the challenges and possibilities for human flourishing.
