Hirohito's interest in marine biology did not make his future succession a surprise. As Emperor Taisho's eldest son, he had grown up expecting to become emperor. He served as regent from 1921 to 1926, then succeeded his father at twenty-five. Taking authority so young placed him among much older and more experienced figures whose influence extended beyond formal government offices.
