In the 1930s, Japan's manufacturing infrastructure was less advanced than those of the US and Europe, and military manufacturing focused on ships and aircraft by Japan's premiere industrial manufacturer Mitsubishi, and armament and tank production by Mitsubishi's "zaibatsu" partners. Aircraft were largely built by Mitsubishi, Tachikawa Aircraft Company, and the Nakajima Aircraft Company which built most of the aircraft. Limited raw materials were also devoted to higher priorities. The goal was to build 5,000 Type 95 in a supporting role, largely by hand and without an assembly line.
