Slice the yellowtail very thinly and fan out on a plate.
Brush the minced garlic over the sashimi evenly. Sprinkle the ginger, scallions, and jalapeno evenly over the fish. Drizzle the soy sauce, yuzu, and ponzu evenly over the fish.
Heat a small saucepan over high heat. Carefully add the olive oil to the extremely hot pan and heat until it just begins to smoke, about 30 seconds. Remove from the heat and carefully pour over the fish. The hot oil will sear the outside of the fish.
Garnish with a lemon wedge and julienned daikon.
