As a result of the ratification of the London Naval Treaty limiting the size of the Imperial Japanese Navy, a movement grew within the junior officer corps to overthrow the government, and to replace it with military rule. This movement had parallels in the Sakurakaisecret society organized within the Imperial Japanese Army. The naval officers established contacts with the ultranationalistInoue Nissho and his "League of Blood", and agreed with his philosophy that to bring about a "Shōwa Restoration", it would be necessary to assassinate leading political and business figures. In March 1932, in the "League of Blood Incident", Inoue's group only managed to kill former Finance Minister and head of the Rikken Minseitō,Inoue Junnosuke, and Director-General of Mitsui Holding Company, Takuma Dan.
Incident
On May 15, 1932, the naval officers, aided by army cadets, and right-wing civilian elements staged their own attempt to complete what had been started in the League of Blood Incident. Prime Minister Inukai Tsuyoshi was shot by eleven young naval officers in the prime minister's residence. Inukai's last words were roughly "If I could speak, you would understand" to which his killers replied "Dialogue is useless". The original assassination plan had included killing the English film starCharlie Chaplin who had arrived in Japan on May 14, 1932, at a reception for Chaplin, planned by Prime Minister Inukai. "These activists, eager to ingest a nativist Yamato spirit into politics, recognised the charged political nature of mass culture". Chaplin's murder would facilitate war with the U.S., and anxiety in Japan, and lead on to "restoration" in the name of the emperor. When the prime minister was killed, his son Inukai Takeru was watching a sumo wrestling match with Charlie Chaplin, which probably saved both their lives. The insurgents also attacked the residence of Makino Nobuaki, the Lord Keeper of the Privy Seal, head of the Rikken Seiyūkaipolitical party, and tossed hand-grenades into Mitsubishi Bank headquarters in Tokyo, and several electrical transformer substations. Aside from the murder of the prime minister, the attempted coup d'état came to nothing, and the rebellion as a whole proved a failure. The participants took a taxi to the police headquarters and surrendered themselves to the Kempeitai without a struggle.
Consequences
The 11 murderers of Prime Minister Inukai were court-martialed. Before the end of their trial, a petition arrived at court containing around 110,000 signatures in blood, which had been signed by sympathizers around the country to plead for a lenient sentence. During the proceedings, the accused used the trial as a platform to proclaim their loyalty to the emperor and to arouse popular sympathy by appealing for reforms of the government and economy. In addition to the petition, the court also received from nine youths in Niigata nine severed fingers to the court as a gesture of their sincerity. The punishment handed down by the court was extremely light, and there was little doubt in the Japanese press that the murderers of Prime Minister Inukai would be released in a couple of years, if not sooner. Failure to severely punish the plotters in the May 15 Incident further eroded the rule of law and the power of the democratic government in Japan to confront the military. Indirectly, it led to the February 26 Incident and the increasing rise of Japanese militarism.
