The Yokohama City Government in Japan has suspended the sale of 12 bluefin tuna due to unverified origin information. The tuna, allegedly from Oma, Aomori Prefecture, lacked necessary certification documents. The Ministry of Agriculture, Forestry and Fisheries has emphasized the need for verification of fishing reports. The Yokohama City Economic Bureau's investigation revealed that the tuna's origin and fishing details failed to meet Japanese fishery regulations. The government is reporting the investigation results to the Ministry of Agriculture, Forestry and Fisheries and the Fisheries Agency for further action.
