Seven Japanese military and political leaders convicted of war crimes by the International Military Tribunal for the Far East are executed by Allied occupation authorities at Sugamo Prison in Tokyo, Japan.

Japan is an island country in East Asia. Located in the Pacific Ocean off the northeast coast of the Asian mainland, it is bordered to the west by the Sea of Japan and extends from the Sea of Okhotsk in the north to the East China Sea in the south. The Japanese archipelago consists of four major islands alongside 14,121 smaller islands, covering 377,975 square kilometers (145,937 sq mi). Divided into 47 administrative prefectures and eight traditional regions, about 75% of the country's terrain is mountainous and heavily forested, concentrating its agriculture and highly urbanized population along its eastern coastal plains. With a population of over 123 million as of 2025, it is the 11th most populous country. The country's capital and largest city is Tokyo.

The International Military Tribunal for the Far East (IMTFE), also known as the Tokyo Trial and the Tokyo War Crimes Tribunal, was a military trial convened on April 29, 1946 to try leaders of the Empire of Japan for their crimes against peace, conventional war crimes, and crimes against humanity, leading up to and during World War II. The IMTFE was modeled after the International Military Tribunal (IMT) at Nuremberg, Germany, which prosecuted the leaders of Nazi Germany for their war crimes, crimes against peace, and crimes against humanity.

Sugamo Prison was a prison in Tokyo, Japan. It was located in the district of Ikebukuro, which is now part of the Toshima ward of Tokyo, Japan.
