Takenaka Corporation, Engineering Fellow | Tokyo, Japan
After completing the master course at Graduate School of Engineering, Kyoto University, Mr. Nakai joined Takenaka Corporation in 1984. Through his career to date, he has consistently been in charge of advanced structures such as large space structures, base isolation and vibration control. His extensive works have resulted in a number of landmark buildings including Fukuoka Dome, Odate Jukai Dome and Sapporo Dome. In 2004, he received JSCA Award, Gengo Matsui Prize and JSSI Award for the structural design of an iconic base-isolated building, PRADA Boutique Aoyama. He also conducted researches on vibration control as a visiting researcher at State University of New York at Buffalo in 1988 and 1989. He played the role of CTBUH Country Representative of Japan from 2009 through 2012.
