On 2 December 2015, Prince Mikasa became the first member of the imperial family to become a centenarian. On his 100th birthday, he said, "Nothing will change just because I turn 100 years old. I'd like to spend my days pleasantly and peacefully while praying for the happiness of people around the world and thanking my wife, Yuriko, who has been supporting me for more than 70 years." At his residence in April 2016, he met the Japanese ambassador to Turkey and took a stroll at the Akasaka Detached Palace.
