The Twenty-Six Martyrs of Japan (日本二十六聖人 Nihon Nijūroku Seijin) were a group of Catholics who were executed by crucifixion on February 5, 1597, at Nagasaki. Their martyrdom is especially significant in the history of Catholic Church in Japan. The Martyrs of Japan were canonized by the Catholic Church on June 8, 1862, by Pope Pius IX, and are listed on the calendar as Sts. Paul Miki and his Companions, commemorated on February 6.
