Emperor Akihito remained in hospital on Friday after his fever went up again, the Imperial Household Agency said at a news conference.
Doctors had said Thursday that the 77-year-old emperor, who has bronchitis, was well enough to be discharged on Friday. But his coughing worsened Friday morning, the agency said, adding that doctors decided to keep him hospital for at least another day.
The emperor was taken to the University of Tokyo Hospital last Sunday night.
The agency said the emperor is expected to return to his official duties by early next week. He and the empress are scheduled to meet Bhutan's King Jigme Khesar Namgyal Wangchuck and his new bride, Queen Jetsun Pema.© Japan Today
