Dr. Takashi Nagai lost his wife in the atomic bombing, and he received a serious injury himself when his right temporal artery was severed. In spite of his serious injuries both in mind and body, he led the rest of the surviving medical staff of the college to conduct relief activity for the injured immediately after the atomic bombing. In the relief activity record, he precisely wrote not only their treatment process but the future symptoms which would appear sometime later as an after-effect of the radiation.
He also continued to write a lot of books such as "The Bells of Nagasaki," "The Rosary Chain," and "Leaving These Children Behind." He prayed for the restoration of Nagasaki and for peace. He gave emotional support to those who were suffering from the after-effects of the atomic bomb and encouraged the people who were tackling the reconstruction. He also gave enormous hope to the victimized children. He died on May 1, 1951 almost 6 years after the atomic bombing.
"Nagasaki City Nagai Takashi Memorial Museum" near Urakami Cathedral can provide more information about his life. In addition, "Nyokodo", a one-room house of two tatami mats where Dr. Nagai lived with his two children, remains the same as it was in those days.
