NAGASAKI -- Former Nagasaki University president Hideo Tsuchiyama, who was exposed to radiation from the atomic bombing of Nagasaki as a student during World War II, died on Sept. 2 of multiple organ failure. He was 92.
Tsuchiyama, who was away from Nagasaki at the time of the atomic bombing on Aug. 9, 1945, was exposed to radiation after re-entering the city the following day. He worked hard to rescue other hibakusha, or people exposed to the bombing and its radiation. At the time, he was a student at Nagasaki Medical College, the predecessor of Nagasaki University School of Medicine.
After studying in the United States, Tsuchiyama became professor at Nagasaki University in 1969. He served as president of the university from 1988 to 1992.
After stepping down, he was deeply involved in a citizens' movement to call for nuclear disarmament and lasting peace.
Tsuchiyama served as a member of a committee to draft a peace declaration read by the Nagasaki mayor on the Aug. 9 anniversary for 25 years from 1990. He was chosen as an honorary citizen by the municipal government in 2010.
In the Mainichi Shimbun's Hibakusha series, Tsuchiyama sounded an alarm bell over the enactment of security-related legislation and moves to revise the war-renouncing Constitution.
Funeral services will be held only among his close relatives.
