The Emperor Emeritus of Japan, aged 91, was discharged from the University of Tokyo Hospital on May 10, 2025, after undergoing a thorough examination of his heart. Accompanied by Empress Emerita Michiko, he left the hospital around 11:30 AM, concluding a four-day stay that began on May 6.
During a routine checkup in mid-April, doctors suspected the Emperor Emeritus might be suffering from myocardial ischemia, a condition characterized by inadequate blood flow to the heart muscle. Following this, he was admitted to the hospital for further testing, which confirmed the diagnosis of asymptomatic myocardial ischemia. This condition typically does not present noticeable symptoms but can lead to serious health issues if left untreated.
The Imperial Household Agency reported that the Emperor Emeritus's condition is linked to age-related arteriosclerosis in the coronary arteries, which has progressed over time. As a result, he will require careful monitoring and medication to manage the condition and prevent excessive physical strain.
Despite being diagnosed with this serious condition, the Emperor Emeritus has shown no significant symptoms, such as chest pain or discomfort, during his hospitalization. He reportedly told medical staff, "I don’t feel any pain or discomfort," highlighting his stable condition throughout the stay.
During his time in the hospital, the Emperor Emeritus underwent a series of tests, including electrocardiograms, X-rays, and CT scans. These examinations confirmed the deterioration of arterial health and the need for ongoing treatment. In 2012, he had previously undergone coronary artery bypass surgery, and in 2022, he was diagnosed with right heart failure, which has required continuous medication.
Empress Emerita Michiko has been a constant source of support for the Emperor Emeritus during this health scare, visiting him daily at the hospital. She was present to accompany him back to their residence in Akasaka Goyochi after his discharge, emphasizing the close bond they share.
As the Emperor Emeritus transitions back to his home life, health experts emphasize the importance of medication to manage his condition and the need for lifestyle adjustments to avoid any undue physical exertion. The Imperial Household Agency will continue to oversee his health care, ensuring that he receives the necessary follow-up treatments and evaluations.
This recent health episode has drawn significant public attention in Japan, where the royal family is closely watched and deeply respected. The Emperor Emeritus has been a beloved figure, and news of his health is met with concern and affection from the Japanese people.
In summary, the Emperor Emeritus's diagnosis of asymptomatic myocardial ischemia and the subsequent treatment plan underscore the challenges of aging and the importance of medical vigilance. As he returns home, the focus will be on maintaining his health and ensuring he continues to enjoy a quality life.
