Steps
1. Ensure all fish are properly chilled and sliced into thin, even pieces approximately 1/4 inch thick.
2. Arrange the slices of tuna, yellowtail, and sea bream on a chilled serving plate with slight overlap, creating an appealing pattern.
3. Place a small dollop of wasabi on the side of the plate.
4. Pour soy sauce into a small dipping bowl.
5. Garnish the plate with shiso leaves or finely shredded daikon radish and a lemon slice if desired.
6. Serve immediately to enjoy the freshness of the fish with wasabi and soy sauce as condiments.
