A series of large antinuclear rallies took place in Fukuoka on Sunday with the organizer saying more than 15,000 people, including from South Korea, took part calling for dismantlement of all nuclear power plants in Japan.

Yukinobu Aoyagi, a leading member of the events, told a gathering in a park in the southwestern city, "We'll work together so as not to see our soil contaminated with radiation."

Lee Dae Su, an antinuclear activist from South Korea, said, "An accident could affect South Korea, so we can't tolerate nuclear plants anymore."

Saeko Uno, 40, who moved to Fukuoka Prefecture from Fukushima Prefecture following the nuclear crisis at the Fukushima Daiichi plant crippled by the March 11 earthquake and tsunami, told event participants that she hopes to see "a world free of nuclear plants."

The protesters then took to the streets marching through downtown Fukuoka, holding placards and signs bearing antinuclear messages.
