## Who they were

Emperor Showa (Hirohito) reigned for 62 years, from 1926 to 1989 — the longest reign in verifiable Japanese history, spanning militarism, catastrophe and rebirth. Under the Meiji Constitution he was sovereign and supreme commander of the armed forces.

## What they did

The extent of his personal responsibility for Japan's war decisions is debated among historians: some emphasize his constitutional passivity, others his involvement in key decisions. In August 1945 he backed the decision to surrender — the "sacred decision" — and broadcast the announcement; most Japanese heard his voice then for the first time. He was not indicted at the Tokyo war-crimes trials, a decision made by the US occupation. The 1946 "humanity declaration" renounced his divinity, and under the 1947 constitution he became a symbol of the state. Postwar he toured the devastated country and pursued marine biology, publishing specialist work. He died on January 7, 1989.

## Legacy

The era that bears his name contains both Japan's darkest years and its remarkable recovery. Assessments of the man himself remain divided.
