An advisory panel to the Tokyo Metropolitan Government submitted a report Saturday calling on it to take steps against pollution at Toyosu, the new destination for Tokyo's famed Tsukiji fish market.

The proposed countermeasures include removing the current surface soil to a depth of 2 meters and replacing it with fresh soil, which would then be topped with an additional 2 1/2 meters of dirt.

The four-member panel also proposed building a bulkhead against toxic underground water beneath the fish-trading compound.
