原子力安全・保安院
According to a government report to the International Atomic Energy Agency in June 2011, "NISA’s lack of independence from the trade ministry, which promotes the use of atomic power, hampered a quick response to the disaster at Tokyo Electric Power Co.’s Fukushima Dai-Ichi plant this year". Following the Fukushima nuclear disaster, there have been questions raised about whether the Nuclear and Industrial Safety Agency has been fulfilling its function as an industry regulator, and whether it should continue to exist.
