Great Martyrdom of Edo

The Great Martyrdom of Edo^[1] was the execution of 50 foreign and domestic Catholics (kirishitans), who were burned alive for their Christianity in Edo (modern-day Tokyo), Japan, on 4 December 1623.

The mass execution was part of the persecution of Christians in Japan by Tokugawa Iemitsu, the third shogun of the Tokugawa shogunate.

Among the executed was Jerome de Angelis (1567–1623), an Italian Jesuit missionary to Japan.
