Prince

The Prince Motor Company was an automobile marque from Japan which eventually merged into Nissan in 1966. It began as the Tachikawa Aircraft Company, a manufacturer of various airplanes for the Japanese Army in World War II. The company changed its name to Prince in 1952 to honor Akihito's formal investiture as Crown Prince of the nation. In 1966, they became part of Nissan, while the Prince organization remained in existence inside Nissan, as Nissan Prince Store in Japan until Nissan consolidated the Prince dealership network into "Nissan Blue Stage" in 1999.

The Prince R380 was a racing car built in 1965 by Prince Motor Company to compete in the Japanese Grand Prix. Following the merger of Prince Motor Company and Nissan Motors in 1966, the R380 was modified into the Nissan R380-II (also known as R380 Mk.II).
