Towards the end of his life, due to his advanced age, Prince Mikasa rarely made public appearances, and regularly used a wheelchair. He and Princess Mikasa lived together at a residence in the grounds of the Akasaka Estate in Motoakasaka, Minato, Tokyo. He underwent heart surgery in 2012, and made a full recovery. His routine included exercising for about 30 minutes each day with his wife at their Tokyo residence, and he often went outdoors for a roll in his wheelchair. About once a week, he would leave his home for a haircut, or to attend various events for other family members. In October 2014, he attended the Tokyo wedding of his granddaughter Princess Noriko, the second daughter of his youngest son Prince Takamado. Palace staff noted that he appeared vigorous until his last days, and that he would always be seen helping his wife to get about. He continued to read newspapers, and enjoyed watching sumo and music programs on television.
