TOKYO >> Japan’s 91-year-old former Emperor Akihito was hospitalized Monday to adjust his heart medication, palace officials said.

Akihito was diagnosed in May with myocardial ischemia, an asymptomatic heart condition of reduced blood flow from the coronary arteries to the heart muscle. He has since been on medication to improve blood flow to his heart while avoiding excessive exercise and reducing liquid intake.

Akihito abdicated in 2019, handing over the Chrysanthemum Throne to his son, current Emperor Naruhito.

Doctors found little improvement in Akinito’s condition and decided to give him an additional treatment to alleviate the burden on his heart, the Imperial Household Agency said.
