Ryoichi Nakagawa (中川 良一 Nakagawa Ryōichi?, 1913–1998) was a Japanese aircraft/automotive engineer. He graduated from Tokyo Imperial University in 1936 and joined Nakajima Aircraft Company in the same year.
He improved Nakajima Sakae engine for Mitsubishi A6M Zero, Nakajima Ki-43 and other planes. He was the chief designer of Nakajima Homare engine for Nakajima Ki-84, Nakajima C6N, Kawanishi N1K and others.
After the World War II, Nakajima Aircraft Company was disbanded and was banned to produce aircraft by the GHQ. It was divided into 12 companies. Two of them were Fuji Heavy Industries (Subaru) and Fuji Precision Industries (Prince Motors). Nakagawa was appointed the senior engineering manager of Prince and led its engineers. He supervised all the Prince vehicles projects including Skyline, Gloria, R380, S390P-1 Royal limousine and others.
