About Thomas Hioji Nishi
Thomas Hioji Nishi was a Japanese Dominican priest whose ministry took him from Japan to the Philippines and Taiwan before he returned to serve Christians in his homeland. The Vatican biography identifies him as the son of Christian martyrs from Hirado. The Vatican account places his studies at the Jesuit college in Nagasaki and his move to Manila in 1614, during the persecution of Christians. There he continued his education at the College of Saint Thomas.
The Japanese bishops’ biography places his birth in 1590 at Ikitsuki in Hirado. It identifies his father as Gaspar and records the deaths of his parents and elder brother in 1609.
The Japanese bishops’ account instead places his journey to Manila around 1620. It states that he entered the Dominican Order in 1624 and was ordained in 1626. The difference leaves the exact timing of his earlier move uncertain.
His family had already experienced the violence directed against Christians. Historian Stephen Turnbull identifies Thomas as a son of Ursula who was spared in 1609. Thomas later became a Dominican priest and was killed in 1634.
The Catholic Church in Norway dates his reception of the Dominican habit to August 15, 1624, and his ordination to 1626. It describes his subsequent mission in Taiwan and his return to Nagasaki in 1629. When Jordan Ansalone joined the mission, the two priests shared the work: Thomas remained in Nagasaki while Jordan traveled to visit Christians elsewhere. Their ministry continued under the danger of arrest.
The Vatican account says that Thomas preached in Japan for five years before he was arrested, tortured and killed. It places his death in 1634 and gives his age as forty-four.
The exact day is reported differently. The official beatification notice in Notitiae places Thomas and Jordan under November 17, 1634. The Dominican collection Witnesses of the Faith in the Orient gives Thomas’s death as November 15. Both place his final imprisonment and execution in the same year.
Thomas is honored with fifteen other martyrs associated with the Dominican family. Pope John Paul II canonized the group on October 18, 1987. The Order of Preachers celebrates their memorial on September 28. Its list identifies Thomas separately among the priests, alongside people who served the same mission as religious brothers and lay collaborators. Their shared commemoration preserves those different roles within one community’s history.
Thomas also left written reports of the persecution. Witnesses of the Faith in the Orient describes letters sent to Formosa and Manila about imprisoned clergy, concealed missionaries and the dangers faced by their hosts. Its list of his writings identifies five letters from 1629–1633 and a report dated September 28, 1633, concerning the deaths of Dominic de Erquicia, Francis Shoyemon and others. These writings preserve his role as a witness to the community’s losses as well as a priest working within it.
