Founder Ryozo Yonehara graduated from the University of Tokyo and worked for the Tokyo Metropolitan Government.

In 1988, he became secretary to Tokyo Governor Shunichi Suzuki. He accompanied the governor and participated in national commemorative projects and various events of the Tokyo Metropolitan Government.

From 1992 to 1994, he worked at the Japan Local Government Center in New York. While attending dozens of international conferences in the U.S., he learned that spouse programs and evening activities were an integral part of MICE. After returning to Japan, he worked as the General Manager of Tokyo Big Sight, Japan's largest convention facility, where he was involved in MICE operations. At that time, he was keenly aware of the lack of activity menus such as cultural experiences.
