Liveblogging World War II: August 14, 1945: The Kyūjō incident
From midnight of August 10, the conference convened in an underground bomb shelter. Hirohito agreed with the opinion of Tōgō, resulting in the acceptance of the Potsdam Declaration.... The War Ministry knew the decision of the conference and stirred up a fierce reaction from many officers who intended do-or-die resistance.... After midnight on 12 August a San Francisco radio station (KGEI) relayed the reply from the Allies, and there was a suggestion that the Allies had decided that the authority of the sovereignty of the Japanese government and the Emperor would be subordinated to the headquarters of the Allies, against the requisition for the protection of the Kokutai from the Imperial Japanese government....
The Ministry of Foreign Affairs interpreted this sentence as restricting sovereignty, but the Japanese Army interpreted it more as enslavement. From 3 o'clock the attendees of the imperial families council basically agreed to the surrender of Japan, yet the cabinet council which was supposed to be held at the same time did not concur. Also, the Supreme Council for the Direction of War tangled with the problem of protection for the Kokutai. After these proceedings, some Army officers for protection of the Kokutai decided that a coup d'état was needed....
Major Kenji Hatanaka, along with Lieutenant Colonels Masataka Ida, Masahiko Takeshita (Anami's brother-in-law), and Inaba Masao, and Colonel Okikatsu Arao, the Chief of the Military Affairs Section, spoke to War Minister Korechika Anami (the army minister and 'most powerful figure in Japan besides the Emperor himself'), and asked him to do whatever he could to prevent acceptance of the Potsdam Declaration. General Anami refused to say whether he would help the young officers in treason. As much as they needed his support, Hatanaka and the other rebels decided they had no choice but to continue planning and to attempt a coup d'état on their own. Hatanaka spent much of August 13 and the morning of August 14 gathering allies, seeking support from the higher-ups in the Ministry, and perfecting his plot....
Around 21:30 on August 14, Hatanaka's rebels set their plan into motion. The Second Regiment of the First Imperial Guards had entered the palace grounds.... Hatanaka, along with Lt. Col. Jirō Shiizaki, convinced the commander of the Second Regiment, Colonel Toyojirō Haga, of their cause, by telling him (untruthfully) that Anami, Umezu, and the commanders of the Eastern District Army and Imperial Guards Divisions were all in on the plan. Hatanaka also went to the office of General Shizuichi Tanaka, commander of the Eastern region of the army, to try to persuade him to join the coup. Tanaka refused, and ordered Hatanaka to go home. Hatanaka ignored the order....
Having set all the pieces into position, Hatanaka and his co-conspirators decided that the Guard would take over the palace at 02:00.... At about the same time, General Anami committed seppuku, leaving a message that, 'I—with my death—humbly apologize to the Emperor for the great crime.' Whether the crime involved losing the war, or the coup, remains unclear....
The cooperation of Mori, as commander of the 1st Imperial Guards Division, was crucial. When Mori refused to side with Hatanaka, Hatanaka killed him, fearing Mori would order the Guards to stop the rebellion. Uehara killed Shiraishi. These were the only two murders of the night. Hatanaka then used General Mori's official stamp to authorize Imperial Guards Division Strategic Order No. 584, a false set of orders created by his co-conspirators, which would greatly increase the strength of the forces occupying the Imperial Palace and Imperial Household Ministry, and 'protecting' the emperor.
The palace police were disarmed and all the entrances blocked. Over the course of the night, Hatanaka's rebels captured and detained eighteen people, including Ministry staff and NHK workers sent to record the surrender speech. The rebels, led by Hatanaka, spent the next several hours fruitlessly searching for Imperial House Minister Sōtarō Ishiwatari, Lord of the Privy Seal Kōichi Kido, and the recordings of the surrender speech. The two men were hiding in the 'bank vault', a large chamber underneath the Imperial Palace. The search was made more difficult by a blackout in response to Allied bombings, and by the archaic organization and layout of the Imperial House Ministry....
At about the same time, in Yokohama, another group of Hatanaka's rebels led by Captain Takeo Sasaki went to Prime Minister Suzuki's office, intent on killing him. When they found it empty, they machine-gunned the office and set the building on fire, then left for his home. Hisatsune Sakomizu had warned Suzuki, and he escaped minutes before the would-be assassins arrived. After setting fire to Suzuki's home, they went to the estate of Kiichirō Hiranuma to assassinate him. Hiranuma escaped through a side gate and the rebels burned his house as well....
Finally, seeing his plan collapsing around him, Hatanaka pleaded with Tatsuhiko Takashima, Chief of Staff of the Eastern District Army, to be given at least ten minutes on the air on NHK radio, to explain to the people of Japan what he was trying to accomplish and why. He was refused. Colonel Haga, commander of the Second Regiment of the First Imperial Guards, discovered that the Army did not support this rebellion, and he ordered Hatanaka to leave the palace grounds.
Just before 05:00, as his rebels continued their search, Major Hatanaka went to NHK studios, and, brandishing a pistol, tried desperately to get some airtime to explain his actions. A little over an hour later, after receiving a telephone call from the Eastern District Army, Hatanaka finally gave up. He gathered his officers and walked out of the NHK studio.... Hatanaka, on a motorcycle, and Shiizaki, on horseback, rode through the streets, tossing leaflets that explained their motives and their actions. Within an hour before the emperor's broadcast, sometime around 11:00, August 15, Hatanaka placed his pistol to his forehead, and shot himself. Shiizaki stabbed himself with a dagger, and then shot himself. In Hatanaka's pocket was found his death poem: 'I have nothing to regret now that the dark clouds have disappeared from the reign of the Emperor.'
