Halloween style protest in Tokyo

This is not any regular anti-nuclear protest in Tokyo.

It has a special theme this time round, halloween.

Dressed up as different characters in costumes, protesters took to the streets rallying against Japan's nuclear power policy.

Some are worried the consequences of restarting the nuclear reactors.

(SOUNDBITE) (Japanese) ANTI-NUCLEAR ACTIVIST HANI KANDA SAYING:

"If they resume the nuclear reactors, we may see in reality those monsters and all the scary things that appear on the halloween day."

One man, dressed as a werewolf was concerned about the future.

(SOUNDBITE) (Japanese) 48-YEAR-OLD ARCHITECT AND ANTI-NUCLEAR PROTESTER, MARIO SAYING:

"Nothing is over yet. We'll see the real health problems starting from now. We don't even know if the Fukushima Daiichi reactors are really shut down."

The operator of Japan's quake-struck Fukushima nuclear power plant said it could not rule out the possibility that the reactors may still be leaking radiation into the sea.

The Fukushima disaster prompted the shutdown of all 50 reactors in Japan for safety checks.

Japan's Prime Minister Yoshihiko Noda's decision to approve the restart of two reactors sparked outrage among anti-nuclear activists.
