The wholesale area is normally restricted to food industry professionals, but opens to the general public on Adachi Market Days, which occur on the 2nd Saturday of odd months (January, March, May, July, September, and November) from 9 AM to 11 AM. During these special days, anyone can purchase fresh fish directly from wholesale stalls and observe the complete market operations including tuna cutting demonstrations. The retail market and restaurant areas remain accessible to all visitors during regular operating hours.
