His major field of studies are Anglo-Japanese relations in the 1930s, the Pacific War and intelligence history. He wrote several books and articles on these topics in English and Japanese. Recent his research topics are arms control and disarmament in the 1930s and Japanese intelligence history in the Cold War. As far as disarmament history is concerned, he wrote “The preliminary negotiations of the second London naval conference in 1934” in 2017 and “Discussion on restriction of aerial bombing in the inter-war period” in 2020 based on primary sources of UK, US, Japan and League of Nations. During his affiliation as a research fellow of ÐÓ°ÉÂÛ̳, he is planning to research the second London Naval conference in 1935-36.

On the other hand, He published a book, Nihon Interigensu Shi (History of Japanese intelligence after the WWII) in 2022. There was neither released official documents nor previous academic works on the topic and it took almost 10 years to collect private sources, interviews and newspaper articles for writing the book.
