Koji Tachibana is an associate professor of philosophy at the University of Chiba (Japan), an international associate scholar at Georgetown University Medical Center (USA), and a research affiliate of the Department of Philosophy at Lund University (Sweden). He studies the notion of virtue from the viewpoints of ancient Greek philosophy (Aristotle’s ethics), contemporary virtue ethics, philosophy of science (neuroscience and human space exploration), and Japanese philosophy. He has published the latest Japanese translation of Aristotle’s Nicomachean Ethics (co-translated with K. Watanabe, Kobunsha, 2015/2016) and three edited volumes: Education and the Philosophy of Virtue: From Theory to Practice and Applications (Toyokan Publishing, 2023; in Japanese), Alternative Virtues: Japanese Perspectives on Christian and Confucian Traditions (Routledge, 2024), and Aristotle in Japan: Reception, Interpretation and Application (co-edited with T. Kondo, Routledge, 2025). He is currently working on a theory of virtue that is both globally adaptive and sensitive to cultural differences.
