Four months after the quake and tsunami hit communities along the Tohoku coastline, fishermen in Fukushima Prefecture and nearby areas still find themselves in uncharted waters as contamination of the sea remains a major obstacle to their business.

Toshihiro Omori, who is in charge of policy planning at Japan Fisheries Cooperatives, said fishermen in Fukushima have not been able to restart their business since the March 11 disaster triggered the nuclear crisis at Tokyo Electric Power Co.'s Fukushima No. 1 power plant.

"I can say that without the nuclear power plant under control, those in the area won't be able to do anything about catching fish," Omori said during a lecture in Tokyo last month.
