Yuko Tojo, the granddaughter of convicted Class-A war criminal Prime Minister Gen. Hideki Tojo, died of interstitial pneumonia Wednesday. She was 73.

Tojo, whose real name was Yoshie Iwanami, was born on the Korean Peninsula in May 1939 to Hidetaka Tojo, the eldest son of Hideki Tojo, while the peninsula was under Japan's colonial rule.

Following his conviction by the International Military Tribunal for the Far East over war crimes committed during his 1941-1944 prime ministership, Hideki Tojo was executed in December 1948.
