Due to the expiration of a number of previously classified materials related to the activities of the Soviet special services during the Second World War, and also due to the especially high public interest in the “case of Richard Sorge” in the last 5 years, a military historian and Doctor of Historical Sciences Mikhail A. Alekseyev introduced into scientific discourse a large number of previously unknown Russian-language documents on this case. These documents are of paramount interest to researchers. For example, it is the first publication of the materials that definitively answer the questions of whether Sorge was a double agent and of what the real reason for the failure of the network of Soviet military intelligence in Japan in 1941 was, as well as of many other pieces of important documentary evidence of the activities of the Soviet secret services in that country.Soon after that, the authors of this article for the first time made a complete translation of the memoirs of Ishii Hanako, Sorge’s Japanese wife, which were analyzed in detail and commented on by the authors of the book Another Sorge. The Story of Ishii Hanako. The memoirs of Ishii Hanako give a chance to take a fresh look at Richard Sorge’s personality, his goals in studying Japan and his approaches to this issue, to form a more personal and, at the same time, objective picture of his character. Together with the case of the “Special Folder” of the Central Committee of the CPSU on perpetuating the memory of Richard Sorge, declassified in 2020, for the first time in history, these materials allow us to fully evaluate Ishii Hanako’s effort to preserve the memory of Sorge in Japan during the period from 1945 to 1964. By comparing the memoirs, the documents of the Soviet side, and by carrying out the research and analytical work, the authors have reached a new level of understanding of the “case of Richard Sorge.”In 2017–2022, a number of new materials devoted to the same case were published in Japan. They reveal the level of awareness of not only Japan’s government and law enforcement agencies, but also of the emperor himself, as well as the division of powers of the special services in the liquidation of Sorge’s intelligence network.
