板垣征四郎
In July 1939, the Emperor quarrelled with his brother, Prince Chichibu, over whether to support the Anti-Comintern Pact, and reprimanded the army minister, Seishirō Itagaki. But after the success of the Wehrmacht in Europe, the Emperor consented to the alliance. On 27 September 1940, ostensibly under Hirohito's leadership, Japan became a contracting partner of the Tripartite Pact with Germany and Italy forming the Axis Powers.
