Naitō Torajirō (内籐 虎次郎 Naitō Torajirō; August 27, 1866–June 26, 1934), commonly known as Naitō Konan (内藤 湖南 Naitō Konan), was a Japanese historian and Sinologist. He was the founder of the Kyoto School of historiography, and along with Shiratori Kurakichi (the founder of the Tokyo School), was one of the leading Japanese historians of East Asia in the early twentieth century. His most well-known book is called Nara. In Japanese history, Naitō argued that Yamataikoku was located in Kyūshū rather than in Kinki.
