The law applies only to the present monarch and can not be applied to his heirs.
The upper chamber of the Japanese parliament on Friday, June 9, passed a law allowing the emperor to resign and transfer power to his heir. According to the adopted document, this process should take no more than three years. The law applies only to the present monarch and can not be applied to his heirs.
Emperor Akihito expressed his desire to resign in August 2016, citing poor health and advanced age. Since the imperial throne in Japan is inherited in the male line, the successor of 83-year-old Akihito must be his son, the 57-year-old Crown Prince Naruhito. This will be the first case of the abdication of the Japanese monarch over the past 200 years. It is expected that the transfer of power will occur next year.
