When was San Lorenzo Ruiz canonized as a saint?

The boat landed at Okinawa and the group was arrested and persecuted because of their Christian religion. They were brought to Nagasaki on July 10, 1636. They were tortured through hanging by their feet, by submerging in water until near death, and by water torture. Needles were also inserted under their finger nails and they were beaten until unconscious. These methods made some of Ruiz's companions recant their faith, but Ruiz never did. On September 27, 1637, Ruiz and his companions were taken to the "Mountain of Martyrs", where they were hung upside down into a pit known as horca y hoya, or tsurushi. This mode of torture was considered as the most painful way to die at the time because it involved the use of rocks to add weight to the person being punished. The individual being tortured suffocated quickly while being crushed by his own weight. Two days after, Ruiz died from hemorrhage and suffocation. His body was cremated and his ashes were thrown into the sea Lorenzo Ruiz was beatified in Manila on February 18, 1981 by Pope John Paul II during his Papal visit to Manila, the first beatification ceremony held outside the Vatican. San Lorenzo Ruiz was elevated to Sainthood and canonized by Pope John Paul II in the Vatican City, Rome on October 18, 1987 making him the first Filipino saint and the first Filipino martyr. His final Words... " Isa akong Katoliko at buong pusong tinatanggap ang kamatayan para sa Panginoon, kung ako man ay may sanlibong buhay, lahat ng iyon ay iaalay ko sa Kanya. ("I am a Catholic and wholeheartedly accept death for the Lord; if I have a thousand lives, all of them I will offer to Him.")" Reference: http://en.wikipedia.org/wiki/San_Lorenzo_Ruiz
