At Sanko Co., Ltd., we offer fresh tuna dissection demonstrations upon request for store anniversary celebrations and various other events.
A thrilling dissection show where you can watch a huge tuna—the kind you rarely get to see—being filleted right before your eyes!
This event lets you enjoy up close the chef's knife skills and watch as the tuna is sliced piece by piece.
