Alfonso Navarrete was a Spanish Dominican friar and missionary who served in the Philippines and Japan during the early 17th century. Born in Logroño around 1571, he joined the Order of Preachers and later traveled to the Far East to minister to various communities. In Japan, he became known for his extensive social work, particularly his efforts to care for abandoned children. During the intense anti-Christian persecutions under the Tokugawa Shogunate, he was arrested and eventually executed by beheading in the Ōmura Domain in 1617.
Missionary work
After serving in the Philippines, Navarrete moved to Japan in 1611. He held leadership roles within the Dominican Order and focused heavily on assisting vulnerable people, which earned him the title "Vincent de Paul of Japan." Beyond his social services, he performed religious duties such as baptizing converts and celebrating Mass. He also attempted to encourage local leaders to maintain their Christian faith during periods of increasing political tension.
Martyrdom and veneration
While traveling with two companions, Ferdinand Ayala and Leo Tanaca, to recover sacred relics, Navarrete was captured by authorities. He was executed on June 1, 1617, in the Ōmura Domain. He is commemorated on several dates, including June 1 alongside his companions, September 10 as one of the 205 Martyrs of Japan, and November 6 as a Dominican martyr.
