In January 1867 the Emperor was diagnosed with smallpox, which caused surprise because Kōmei had allegedly never been ill before. On 30 January 1867 he suffered a fatal violent bout of vomiting and diarrhea, and had purple spots on his face. Emperor Kōmei's death was distinctly convenient for the anti-bakufu forces whom Kōmei had consistently opposed. It was rumored at the time that he was assassinated either by radicals from Choshu, or radical officials in the court. British diplomat Sir Ernest Satow wrote, "it is impossible to deny that Emperor Kōmei's disappearance from the political scene, leaving as his successor a boy of fifteen or sixteen fourteen, was most opportune". However, there is no evidence of this and it is generally believed that he was simply one more victim of what was a worldwide pandemic at the time. Nevertheless, by the time of Emperor Kōmei's death the government was faced with bankruptcy and near collapse. Japan was also surrounded by colonial powers, who stood poised to gain considerable influence with substantial investments in Japanese trade. Kōmei's son, Imperial Prince Mutsuhito, was crowned as Emperor Meiji on 12 September 1868 and these issues were put to rest under the Meiji Restoration.
