He has written several books in the field of international relations, such as an evaluation of geopolitics, Halford Mackinder, and Nicholas J. Spykman. He perceives Japan to have developed a successful welfare system.
He is a subscriber to the philosophy of Edmund Burke, who he regards as the antithesis of Rousseau. He considers Rousseau to be the father of modern European philosophy (Kant, Hegel, Marx, Darwin, etc.). He is the author of many critiques and evaluations of Marxist-Leninism, the Frankfurt School, postmodernism, postcolonialism, and democracy in general. He notably wrote an early criticism of the concept of gender studies before it had become popular in the Japanese academy.
In 2000, Nakagawa wrote a rather surprising book that accused Fumimaro Konoe of responsibility for the Pacific War. It has been through several reprintings. Unlike some other modern conservatives, Nakagawa believes the Pacific War was pointless and cruel.
