TOKYO: Japan's tuna market, the world's largest, is taking an outsized hit from the COVID-19 pandemic, pressuring restaurants and wholesalers at Tokyo's sprawling Toyosu fish market to adapt to survive.

Businesses had hoped for more activity after Japan lifted its state of emergency in late May, but big events such as shareholder meetings and wedding banquets have remained on hold while many Japanese are still wary of going to restaurants.
