Mitsumasa Yonai
Two Japanese incursions were made into Soviet territory during the spring of 1938 and 1939: the Battle of Lake Khasan and the Manchurian-Mongolian; both were Japanese defeats. More right-wing activity began when Hiranuma Kiichirō became prime minister and the August 23, 1939 Molotov–Ribbentrop Pact rattled Japanese diplomacy. Nobuyuki Abe became prime minister, and the United States denounced the defunct Anglo-Japanese Alliance. Mitsumasa Yonai succeeded Abe as prime minister. In turn, Fumimaro Konoe succeeded Yonai as prime minister and formed a totalitarian, right-wing government in July 1940.
