A team of South Korean experts arrived in Japan on Sunday for an unprecedented six-day visit that will include a trip on Tuesday to the crippled Fukushima No. 1 nuclear power plant, where the government is planning to release treated water into the ocean as part of a decadeslong decommissioning process.

Concerned about the aftereffects of the March 2011 nuclear disaster, South Korea continues to uphold a ban on seafood and marine imports from the area around the Fukushima No. 1 plant, despite Japanese government insistence the food is safe.

Nuclear Safety and Security Commission Chairperson Yoo Guk-hee is heading a 21-member team of government experts, who on Monday met with nuclear officials from plant operator Tokyo Electric Power Company Holdings (Tepco) and various government agencies that oversee Japan¡¯s nuclear power industry. They will tour the plant on Tuesday and Wednesday, paying particular attention to Japan¡¯s plans to discharge treated water, currently being stored at Fukushima No. 1, into the ocean.
