The rise of militant forces in Japan resulted not from a seizure of power by a new political party but from the growing influence of such elements at the top of the political hierarchy. During the 1920s, a multiparty system based on democratic practices appeared to be emerging. Two relatively moderate political parties, the Minseito and the Seiyukai, dominated the Diet and took turns providing executive leadership in the cabinet. Radical elements existed at each end of the political spectrum, but neither militant nationalists nor violent revolutionaries appeared to present a threat to the stability of the system. In fact, the political system was probably weaker than it seemed at the time. Both of the major parties were deeply dependent on campaign contributions from powerful corporations (the zaibatsu), and conservative forces connected to the military or the old landed aristocracy were still highly influential behind the scenes. As in the Weimar Republic in Germany during the same period, the actual power base of moderate political forces was weak, and politicians unwittingly undermined the fragility of the system by engaging in bitter attacks on each other. The road to war in Asia began in 1928 when Zhang Xueliang, son and successor of the Japanese puppet Marshall Zhang Zuolin (see Chapter 5) decided to integrate Manchuria into the Nanjing republic. Appeals from Tokyo to Washington for a U.S. effort to restrain Chiang Kai-shek were rebuffed. Already suffering from the decline of its business interests on the mainland, after 1929 Japan began to feel the impact of the Great Depression when the United States and major European nations raised their tariff rates against Japanese imports in a desperate effort to protect local businesses and jobs. The value of Japanese exports dropped by 50 percent from 1929 to 1931, and wages dropped nearly as much. Hardest hit were the farmers as the price of rice and other staple food crops plummeted. At the same time, militant nationalists, outraged at Japanís loss of influence in Manchuria, began to argue that the Shidehara policy of peaceful cooperation with other nations in maintaining the existing international economic order had been a failure. It was undoubtedly that vision that had motivated the military coup díétat launched in Mukden in the early fall of 1931. During the early 1930s, civilian cabinets managed to cope with the economic challenges presented by the Great Depression. By abandoning the gold standard, Prime Minister Inukai Tsuyoshi was able to lower the price of Japanese goods on the world market, and exports climbed back to earlier levels. But the political parties were no longer able to stem the growing influence of militant nationalist elements. Despite its doubts about the wisdom of the Mukden incident, the cabinet was too divided to disavow it, and military officers in Manchuria increasingly acted on their own initiative. In May 1932, Inukai Tsuyoshi was assassinated by right-wing extremists. He was succeeded by a moderate, Admiral Saito Makoto, but ultranationalist patriotic societies began to terrorize opponents, assassinating businessmen and public figures identified with the policy of conciliation toward the outside world. Some, like the publicist Kita Ikki, were convinced that the parliamentary system had been corrupted by materialism and Western values and should be replaced by a system that would return to traditional Japanese values and imperial authority. His message, ďAsia for the Asians,Ē had not won widespread support during the relatively prosperous 1920s but increased in popularity after the Great Depression, which convinced many Japanese that capitalism was unsuitable for Japan. During the mid-1930s, the influence of the military and extreme nationalists over the government steadily increased. Minorities and left-wing elements were persecuted, and moderates were intimidated into silence. Terrorists tried for their part in assassination attempts portrayed themselves as selfless patriots and received light sentences. Japan continued to hold national elections, and moderate candidates continued to receive substantial popular support, but the cabinets were dominated by the military or advocates of Japanese expansionism. In February 1936, junior officers in the army led a coup in the capital city of Tokyo, briefly occupying the Diet building and other key government installations and assassinating several members of the cabinet. The ringleaders were quickly tried and convicted of treason, but under conditions that strengthened even further the influence of the military in the halls of power.
