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.

The Datsun Truck is a compact pickup truck made by Nissan in Japan from 1955 through 1997. It was originally sold under the Datsun brand, but this was switched to Nissan in 1983. It was replaced in 1997 by the Frontier and Navara. In Japan, it was sold only in Nissan Bluebird Store locations.
