Japan's emperor has heart by-pass
Japanese officials have said that Emperor Akihito's heart-bypass surgery has successfully ended.
The Imperial Household Agency said that the operation safely ended about six hours after the emperor entered the operation room at the University of Tokyo Hospital.
A medical team from the hospital, joined by another team from Juntendo University Hospital, operated on the 78-year-old emperor.
The surgery was scheduled after tests last weekend showed that his heart condition had worsened compared to a year ago.
The emperor has had various health problems in recent years, including pneumonia and prostate cancer. He has cut back on public duties but still appears regularly at events.
