The Nissan Junior was a series of medium-sized pickup trucks built from 1956 until 1982. It was introduced to fill the gap between the smaller, Datsun Bluebird based Datsun Truck, and heavier load capacity Nissans under the Nissan Diesel brand, like the 80-series trucks. After the merger with Prince Motor Company, the Junior and the Prince Miler were combined, sharing most of the characteristics, with the Junior sold at Nissan Bluebird Store Japanese dealerships, and the Miler sold at Nissan Prince Store until 1970.
