Tokyo's Toyosu fish market, which opened in 2018 to replace the Tsukiji market, is facing tough times with both trade volume and prices of high-end fish and other marine products tumbling in the face of the coronavirus pandemic.

The wholesale market is famous for its tuna auctions, but trading volume for the fish has fallen by roughly half from a year earlier amid sharp declines in the number of customers at restaurants, especially foreign tourists, according to the operator.

Most of the seafood at the Toyosu market is snapped up by professional buyers supplying customers such as upscale sushi restaurants, but amid the current market conditions some unsold products end up being bought online at discount prices by members of the public.
