"Even today I constantly feel the sting of conscience over my failure to fully grasp the criminality of war," he wrote.
In a 1994 interview with Japanese newspaper Yomiuri Shimbun, the prince recalled, "I was strongly shocked when an officer told me that the best way to train new soldiers is to use a living prisoner of war as the target of bayonet practice."
After the war he devoted himself to the study of ancient Asian history and taught at such universities as Tokyo Woman's Christian University and the Tokyo University of the Arts where he was paid US$6.40 a month.

Together with Princess Yuriko, 93, whom Prince Mikasa married in 1941, he had three sons and two daughters, but the three princes died in 2002, 2012 and 2014.
When he turned 100 last December, The Japan Times reported the prince issued a statement thanking Yuriko for her support during their over 70 years of marriage, saying, "Nothing will change just because I turn 100 years old."
