On January 30, 2006, the Center on Japanese Economy and Business (CJEB) hosted the lecture, "Agents of Change: Women CEOs of U.S. Based Japanese Subsidiaries." The speakers were Melanie Hart, President of the TASUS Corporation, a subsidiary of Nagoya-based auto parts manufacturer Tsuchiya, and Yuki Hattori, President of Dentsu Communications Inc., a U.S. unit of advertisement giant Dentsu Corporation. The two were joined by Columbia Business School Associate Professor Schon Beechler. The program, sponsored by the Mitsui USA Foundation, was the seventh annual Mitsui USA Symposium, which kicked off the 20th anniversary celebration of the CJEB.
