The Little Crown of the Japanese Martyrs
In the book What Happened at Pontmain by Abbe M. Richard we read that "This symbolic crown, or little rosary, was approved by Pope Pius IX when he canonized the Japanese Martyrs [of Nagasaki, on June 8, 1862]. It is said to beg the protection of the martyrs upon the Church, and for the conversion of Japan and the Far East. It is recited in the following manner:
a) On the cross, acts of faith, hope, and charity;
b) On each of the small beads, the following invocations: 'Sweet Heart of Mary, be my salvation';
c) 'My Jesus mercy!'
d) On the large beads, one adds to these two invocations the following: "Eternal Father, I offer Thee the Most Precious Blood of Jesus Christ in reparation for my sins and for the needs of Holy Mother Church."
As you can see, this devotion was created for the 26 Martyrs of Nagasaki but of course we can pray this same "Little Crown" for the 52 + 1 Martyrs of Kyoto, and, indeed, for all the Martyrs in Japan.
