Word of Saigō's academies was greeted with considerable concern in Tokyo. The government had just dealt with several small but violent samurai revolts in
Kyūshū, and they found the prospect of rebellion by the numerous and fierce Satsuma samurai, led by the famous and popular Saigō, an alarming one. In December 1876, the Meiji government sent a police officer named Nakahara Hisao and 57 other men to investigate reports of subversive activities and unrest. The men were captured, and under
torture, confessed that they were spies who had been sent to assassinate Saigō. Although Nakahara later repudiated the confession, it was widely believed in Satsuma and was used as justification by the disaffected samurai that a rebellion was necessary in order to "protect Saigō". Fearing a rebellion, the Meiji government sent a warship to Kagoshima to
remove the weapons stockpiled at the Kagoshima arsenal on 30 January 1877. This, accompanied by an elimination of samurai rice stipends in 1877, provoked open conflict. Outraged by the government's tactics, 50 students from Saigō's academy attacked the Somuta Arsenal and carried off weapons. Over the next three days, more than 1000 students staged raids on the naval yards and other arsenals. Presented with this sudden success, the greatly dismayed Saigō was reluctantly persuaded to come out of his semi-retirement to lead the rebellion against the central government. In February 1877, the Meiji government dispatched
Hayashi Tomoyuki, an official with the
Home Ministry with Admiral
Kawamura Sumiyoshi in the warship
Takao to ascertain the situation. Satsuma's governor,
Oyama Tsunayoshi, explained that the uprising was in response to the government's assassination attempt on Saigō, and asked that Admiral Kawamura (Saigō's cousin) come ashore to help calm the situation. After Oyama departed, a flotilla of small ships filled with armed men attempted to board
Takao by force, but were repelled. The following day, Hayashi declared to Oyama that he could not permit Kawamura to go ashore when the situation was so unsettled, and that the attack on
Takao constituted an act of
lèse-majesté. to fight the Satsuma rebellion in 1877 On his return to
Kobe on 12 February, Hayashi met with General
Yamagata Aritomo and
Itō Hirobumi, and it was decided that the
Imperial Japanese Army would need to be sent to Kagoshima to prevent the revolt from spreading to other areas of the country sympathetic to Saigō. On the same day, Saigō met with his lieutenants
Kirino Toshiaki and
Shinohara Kunimoto and announced his intention of marching to Tokyo to ask questions of the government. Rejecting large numbers of volunteers, he made no attempt to contact any of the other domains for support, and no troops were left at Kagoshima to secure his base against an attack. To aid in the air of legality, Saigō wore his army uniform. Marching north, his army was hampered by the deepest snowfall Satsuma had seen in more than 50 years, which, because of the similarity to the weather that had greeted those setting out to enact the Meiji Restoration nine years earlier, was interpreted by some as a sign of divine support. ==The Southwestern War==
