He was known as Prince Tsugu as a child (like his granddaughter is Princess Toshi today){Source}. He was educated primarily by private tutors before attending Gakushūin School from 1940-1952{Source}.He briefly studied Political Science at Gakushuin University, but never received a degree{Source}.  He has written papers for scholarly journals, namely Gene and the Japanese Journal of Ichthyology{Source}.

Since then, he along side his wife, then Crown Princess Michiko, who he married in 1959 have visited 37 countries on official visits{Source}.

His father died in January 1989, and he was formally invested as Emperor almost two years later, in November 1990{Source}. In 1998, during a state visit to the United Kingdom, he was invested with The Most Noble Order of the Garter.
