A government advisory panel on Wednesday resumed discussions on remaining issues of Emperor Akihito's abdication, including his status after becoming the first living Emperor to relinquish the throne in around 200 years.
Four university professors were summoned to the panel's 10th meeting, of which three proposed the 83-year-old Emperor after his abdication should assume the historical title of joko in line with past imperial practice.
The three also proposed Emperor Akihito's future tomb be equivalent in status to those of past emperors.
