Joam Mattheus Adami was an Italian Jesuit missionary born in Mazara del Vallo in 1576. After completing his theological studies in Rome and Macau, he traveled to Japan in 1604 to spread the Catholic faith. Despite being exiled to Macau in 1614 due to anti-Christian edicts, he returned to the country in 1618 to continue his work. He eventually moved to the Oshu region to serve local believers during a period of intense persecution. He was captured and martyred in Nagasaki in 1633.
