Abe met the Emperor at the Imperial Palace on Thursday to report privately on matters of state.

Government officials say he briefed the Crown Prince on situations on domestic and foreign affairs.
The meetings took place ahead of a government ceremony on Sunday to mark Emperor Akihito's 30 years on the throne.
