Japan's 78-year-old emperor was recuperating Saturday from a effective cardiac bypass surgical procedure at the University of Tokyo Hospital, in accordance to Japanese public broadcast NHK.
Emperor Akihito's surgical treatment lasted just about five hours.
Akihito, a ceremonial but adored figure in Japan, has struggled from poor health in current months and has been in the hospital several times.
Tsugunomiya Akihito was born on December 23, 1933 in Tokyo to Emperor Hirohito and Empress Nagako Kuniat as their 5th kid and first son.
In accordance to Japanese legend, he is a immediate descendant of Japan's first emperor Jimmu, circa 660 BC. Akihito means "shining pinnacle of virtue," and Tsugunomiya means "prince of the august succession and enlightened benevolence."
On November 12, 1990, Akihito ascended to the Chrysanthemum Throne -- the most ancient hereditary monarchy in the world -- as the One hundred and twenty fifth Emperor of Japan, one year and ten months after the passing away of Emperor Hirohito.
The position, per Japan's constitution, is described as "the symbol of the state and of the unity of the people." That said, the office's participation in day-to-day govt affairs tends to be little.
Akihito broke from precedent adhering to Japan's epic 9.0 magnitude earthquake and succeeding tsunami last year, when he gave a historical, televised presentation on March 16. In it, he inspired citizens to put forth their "best effort to save all struggling people" and he congratulated his countrymen's management of the crisis.
