Japan’s Emperor Emeritus Akihito has been released from hospital in Tokyo after undergoing a heart examination.

The 91-year-old Emperor Emeritus was diagnosed with a high probability of myocardial ischemia in a regular checkup and subsequent examination. The condition occurs when blood flow from the coronary arteries to the heart muscle is insufficient. He had not complained of any symptoms.

The Emperor Emeritus was admitted to the University of Tokyo Hospital on Tuesday for a detailed examination. Empress Emerita Michiko visited her husband at the hospital daily. On Saturday morning, the Emperor Emeritus, accompanied by his wife, returned to their residence at the Akasaka Estate by car.
