For those interested in the history of Catholicism in Japan, a reader points us to the story of Dr. Takashi Nagai..

one of the prominent lay leaders of the Catholic community at Nagasaki during and after WWII. He was a pioneer in radiology research before the war and was dying of leukemia before the A-bomb was dropped. After the war, his reflections on the devastations of the war became quite popular in Japan and helped the Japanese to make sense of the tragedy. His cause is up for canization to sainthood right now.
