Yohei Kawanishi is a Japanese scholar of international relations and a research fellow at the Nakasone Peace Institute. He graduated from the Faculty of Law at Keio University and earned a Ph.D. in law from Keio University's Graduate School of Law. Before joining the institute, he worked as a specialist analyst at Japan's Ministry of Foreign Affairs. His research focuses on Soviet and Russian foreign policy and security, intelligence, and the history of Soviet-Japanese relations, particularly how Soviet leaders assessed intelligence and incorporated it into diplomatic and military decision-making. In "Sutārin no Kyokutō Senryaku 1941–1950: Interijensu to Anzen Hoshō Ninshiki," he draws on Russian primary sources to examine Stalin's perceptions of Japan and East Asia from the German-Soviet War through the beginning of the Korean War, tracing how intelligence influenced Soviet military strategy and foreign-policy decisions.
