Nearly a decade since the March 2011 tsunami swept Fukushima Prefecture and other parts of northern Japan, dozens of officers from police forces nationwide are still dispatched to Fukushima every year to search for 196 people still unaccounted for after the disaster.

They are dubbed the "Ultra Police Force," a name coined by the late Eiji Tsuburaya, founder of the popular TV program "Ultraman" and a native of Sukagawa, Fukushima Prefecture.

"What we can do right now is search for them every day," one of the police officers said.
