七七事变
In 1991, Princess Takamatsu and an aide discovered a twenty-volume diary, written in Prince Takamatsu's own hand between 1934 and 1947. The diary, which the magazine "Chūō Kōron" obtained, revealed the late prince had opposed the Kwantung Army's incursions in Manchuria in September 1931 and the expansion of the July 1937 Marco Polo Bridge Incident into a full-scale war against China.
