General Yamanashi Hanzō, the individual appointed to direct Japan’s Martial Law Headquarters on 20 September 1923, was no stranger to demanding administrative or military tasks. Yamanashi was a seasoned soldier who had served in active combat during Japan’s previous three wars: the Sino-Japanese War of 1894-95, the Russo-Japanese War of 1904-05, and the First World War, 1914-1918. His previous experiences did little to prepare him for the tasks he faced in post disaster Tokyo.
This earthquake took place on September 1st, 1923. The epicenter of the earthquake was located near Oshima Island in Sagama Bay in the south of Japan.
