A gold and silver mine site recommended by the Japanese government for UNESCO World Heritage status is unlikely to be included in the 2023 list, education minister Shinsuke Suematsu said Thursday, as the organization did not forward the recommendation to its advisory body.

UNESCO cited incomplete information on the recommendation form as the reason for not reviewing the mine on Sado Island in Niigata Prefecture for next year's list, Suematsu said, adding that the government plans to submit its recommendation again.
