A university professor in Japan may have helped shed light on the final fate of Japan’s infamous wartime prime minister Hideki Tojo. In 2018, Hiroaki Takazawa came across declassified documents at the US National Archives and after years of fact-checking, he released findings that describe a secretive mission on a US army aircraft over the Pacific Ocean, where Tojo’s ashes appear to have been scattered 50km east of Yokohama. Tojo was one of the masterminds behind the attack on Pearl Harbour in 1941, which forced the US into World War II.
