Tanzawa Mountains
Nissan's central research is inside the Oppama Plant site, Yokosuka, which began its operation in 1961, at the former site of Imperial Japanese Navy's Airborne Squadron base. In 1982, Nissan's technical centers in Suginami, Tokyo and Tsurumi, Yokohama were combined into one: Nissan Technical Center (NTC) in Atsugi, Kanagawa, at the foot of Mount Ōyama of the Tanzawa Mountains. At its 30th anniversary in 2012, NTC employed 9,500 employees in product development, design, production engineering, and purchasing.
