Emperor Emeritus Akihito was discharged from a hospital in Tokyo on May 10 after undergoing cardiac tests.
Akihito, 91, suffers from myocardial ischemia, which is a lack of blood flow to the heart.
He was hospitalized May 6.
Accompanied by Empress Emerita Michiko, Akihito left the University of Tokyo Hospital in the Hongo district of the capital shortly after 11:30 a.m. and driven to their residence in the Akasaka district.
A routine checkup on April 15 detected suspected myocardial ischemia, and the diagnosis was confirmed May 4.
Akihito underwent coronary artery bypass surgery at the University of Tokyo Hospital in February 2012. This was the first time he had been hospitalized since then.
The Imperial Household Agency said he appeared to have no difficulty in his daily life, including speaking and walking, and had no subjective symptoms.
