The siege of Tomioka Castle (2-6 January 1638) was a defeat of the rebel peasants and ronin during Shimabara Rebellion. After a successful uprising in Shimabara Domain, several thousand of rebels crossed the sea to the nearby Amakusa islands, domain of the Terazawa family, to help the local Christians who rose to arms at the same time. The local Terazawa samurai suffered a devastating defeat at Hondo Castle, but the survivors took refuge in Tomioka Castle, where they were able to repulse several assaults.[1]
