Today, more than 25 years after the end of the Cold War, the members of the Bulletin of the Atomic Scientists Science and Security Board have looked closely at the world situation and found it so threatening that the hands of the Doomsday Clock must once again be set at three minutes to midnight.

A careful review of threats leads the Bulletin's Science and Security Board to conclude that the risk of civilization-threatening technological catastrophe remains high, and that the hands of the Doomsday Clock should therefore remain at five minutes to midnight.

In the city's Koenji neighborhood, a large group of mostly younger protesters, many in costume, chanted and banged drums. In Shiba Park, an older and more sober group demanded the closure of the Hamaoka nuclear power plant, located near a fault line about 200 kilometers (125 miles) southwest of Tokyo.
