Kinoaki Matsuo (Japanese: 松尾樹明) was a Foreign Affairs Officer and Navy Admiralty Liaison, Black Dragon Society member, writer, and Japanese Navy strategizer. In 1940 Kinoaki Matsuo published a book on how Japan planned to win a war with the United States. He analyzed the supposed strategical Japanese planning for defeating U.S. Naval forces by suggesting that "the United States fleet in its attempt to cross the Pacific can be imagined by recalling the end of the Russian Baltic Fleet in the Sea of Japan."
