On 22 September 1987, the Emperor underwent surgery on his pancreas after having digestive problems for several months. The doctors discovered that he had duodenal cancer. The Emperor appeared to be making a full recovery for several months after the surgery. About a year later, however, on 19 September 1988, he collapsed in his palace, and his health worsened over the next several months as he suffered from continuous internal bleeding. The Emperor died at 6:33 AM on 7 January 1989 at the age of 87. The announcement from the grand steward of Japan's Imperial Household Agency, Shoichi Fujimori, revealed details about his cancer for the first time. Hirohito was survived by his wife, his five surviving children, ten grandchildren, and one great-grandchild.
