Prince Katsura, the 66-year-old cousin of Emperor Akihito, died of heart failure in the University of Tokyo Hospital on Sunday morning, the government and Imperial Household Agency said.
He was the sixth in line to the Japanese imperial throne.
The prince, who has been in ill health for some time, was rushed to hospital early Sunday and died just before 11 a.m., TV Asahi reported. In 1988, he had surgery for acute subdural hematoma, and in 2008, was hospitalized for septicemia.
The prince, who was not married, had been confined to a wheelchair for the past few years.© Japan Today
