Prince Charles and his wife, Diana, will attend the enthronement of Emperor Akihito of Japan in November, Buckingham Palace announced Wednesday.
The royal couple will be in Japan while Britain is observing Remembrance Sunday, the annual commemoration of the nation's war dead.
The royal couple will lay a wreath at the Commonwealth War Graves Cemetery in Yokohama, where more than 1,200 British and other Allied soldiers killed in World War II are buried, the palace said.
Charles' father, Prince Philip, attended the funeral of Emperor Hirohito last year. Prime Minister Margaret Thatcher's government resisted demands by British war veterans to boycott the funeral.
