The Russians came late to Japan, arriving after the Portuguese and other European powers. But as soon as they arrived, Russia tried to use spies and espionage to learn more about their neighbor—with various degrees of success. Sometimes, it failed miserably, like Russia’s early attempts to make contact with pre-Meiji Japan, or the debacle during the Russo-Japanese War. Other times, they were wildly successful, like during the Battle of Khalkin Gol or with Richard Sorge’s spy ring during the Second World War.

James D. Brown covers Russia and the Soviet Union’s efforts to learn more about Japan in Cracking the Crab: Russian Espionage Against Japan, from Peter the Great to Richard Sorge (Hurst, 2025), covering much both the famous examples of Russian spycraft, and the lesser-known missions—like Operation Postman, a successful effort to read the mail of Japanese diplomats in Italy.

James is Professor of Political Science at Temple University, Japan. He is a specialist on East Asian politics and a regular media contributor, including for the BBC. His books include Japan, Russia and their Territorial Dispute (Routledge: 2016); and Japan’s Foreign Relations in Asia (Routledge: 2018) and The Abe Legacy (Lexington Books: 2023)
