|Information|| Omura Sumitada, adopted from his original Arima family in Shimabara to the Omura family, succeeded to the Omura name as the lord of the manor in the Warring States period.
Fighting against other neighboring Sengoku Daimyos such as the Ryuzojis in Saga, the Matsuuras in Hirado, the Gotos in Takeo, Sumitada expanded his domain surrounding Omura Bay.
Goto Takaaki, who originally was from the Omura family but was put for adaption to the Gotos because of Sumitada, was always hostile toward Sumitada.
Sumitada opened Yokoseura, Fukuda,and Nagasaki Ports to trade with the West (especially Portugal). He also allowed Christianity, and became the first Kirishitan (Christian) Daimyo in Japan. He engaged in many historically important projects, among which is the Tensho Embassy, the first official visit to Europe.
Sumitada, as a Kirishitan Daimyo, recommended Christianity to the local people. As a result, in Omura, some temples and shrines were destroyed by Kirishitan, and the whole area turned into Christianity. Muro-ji Temple at Sanjo Castle was used as a church, and Sumitada donated the Nanban Trade ports Nagasaki and Mogi to the Society of Jesus. This is how he came to have a deep relationship with Christianity.
According to a missionary Luis Frois, the number of the christians at the time was over 60000.
After his death in Omura, his body was buried at Muro-Ji Temple by Sanjo Castle, but it is said that , after the rennovation of the temple, his body was moved to Honkyo-Ji Temple. Unfortunately, nobody knows where his tombstone is.
