Nissan is headquartered in Japan. Its corporate headquarters are in Yokohama, in Kanagawa Prefecture, making Japan the single canonical country answer.
Nissan Motor Co., Ltd. was established in 1933 and grew from Japan’s early automobile industry. The company’s name is associated with the Nissan zaibatsu, a major Japanese business group, and Nissan later became one of Japan’s best-known global carmakers.
A common mix-up is confusing Nissan’s nationality with the locations of its overseas factories, design studios, or alliance partners. Nissan operates internationally and has long been linked with Renault and Mitsubishi through the Renault–Nissan–Mitsubishi Alliance, but those partnerships do not change its headquarters country.
Nissan sells vehicles under the Nissan brand and has also operated the Infiniti luxury marque. Its headquarters location in Yokohama is a useful neighbouring fact: Yokohama is Japan’s second-largest city by population and a major port city south of Tokyo.
