Koichi HOSOKAWA
Koichi Hosokawa, Ph.D. in Law
Professor Emeritus, Japan Women’s University
Koichi Hosokawa is Professor Emeritus at Japan Women’s University and a legal scholar specializing in consumer law, consumer policy, and consumer education. His broader research interests include corporate social responsibility (CSR), business ethics, public utility regulation, public transportation policy, and ethical consumption.
He studied economic law at the Graduate School of Law, Waseda University, and subsequently pursued doctoral studies in civil and economic law at the Graduate School of Law, Hitotsubashi University. He later received his Ph.D. in Law from Hitotsubashi University.
Before entering academia, Hosokawa worked at the National Consumer Affairs Center of Japan (NCAC), where he was engaged in research on consumer affairs and consumer policy and served in positions including Assistant Director of the Research Division.
He was a Visiting Scholar at the University of Wyoming College of Law in the United States, where he conducted research on U.S. consumer law and consumer protection with Professor Dee Pridgen. His research focused particularly on U.S. consumer protection mechanisms, including the regulation of unfair or deceptive acts or practices (UDAP), the Federal Trade Commission Act, and state consumer protection laws.
Hosokawa has also contributed to introducing U.S. consumer law scholarship to Japan. He translated into Japanese Professor Pridgen’s work on the role of state and private enforcement in U.S. consumer protection, which was published in the Japanese legal journal Horitsu Jiho (The Law Journal) in November 1999.
Hosokawa subsequently pursued a long academic career at Japan Women’s University, where he taught and conducted research in consumer law, consumer policy, and related fields until his retirement, after which he was appointed Professor Emeritus.
In addition to his academic work, he has served on numerous governmental and public advisory bodies concerned with consumer policy and regulation. His appointments have included membership on the Consumer Commission of the Cabinet Office, the Consumer Education Promotion Council of the Consumer Affairs Agency, the Tokyo Metropolitan Consumer Affairs Council, and other national and local government committees. He has also contributed to advisory and research bodies of the Financial Services Agency, the Ministry of Economy, Trade and Industry, and the Ministry of Education, Culture, Sports, Science and Technology.
His research has addressed a wide range of issues concerning the protection of consumer interests, including consumer law and policy, consumer education, corporate social responsibility (CSR), ethical consumption, public utility charges, and consumer interests in public transportation.
In recognition of his longstanding contributions to consumer affairs, consumer policy, and consumer education, Hosokawa received the Prime Minister’s Commendation for Distinguished Contributions to Consumer Support Activities in 2021.
His publications include books and articles on consumer policy, consumer law, consumer education, and legal issues encountered by consumers in everyday life. Through his academic research, teaching, public service, and international comparative work, he has contributed to the development of consumer law and consumer policy in Japan.
