The Emperor Emeritus, 91, was discharged from the University of Tokyo Hospital in Bunkyo Ward, Tokyo, on Saturday morning, after being admitted for cardiac examinations. He left the hospital accompanied by the Empress Emerita.

According to the Imperial Household Agency, a routine medical checkup in mid-April suggested possible myocardial ischemia — a reduction in blood flow to the heart muscle — prompting additional tests.

Subsequent examinations confirmed a high likelihood of myocardial ischemia, and from May 6 he underwent detailed evaluation during his hospital stay.

The agency announced on the day that the Emperor Emeritus had been diagnosed with asymptomatic myocardial ischemia.
