Rinse and cook the rice according to package instructions using a rice cooker or stovetop. While the rice is still warm, gently mix in the rice vinegar, sugar, and salt until evenly combined. Set aside to cool slightly.
1.75 cups short-grain rice, 2 tablespoon rice vinegar, 2 teaspoon granulated sugar, ½ teaspoon salt
Lightly season the salmon all over with salt and garlic powder. Bake at 400°F (200°C) for 12-15 minutes or air fry at 400°F (200°C) for 9-12 minutes until cooked through. Remove and flake into small pieces with a fork.
8 oz salmon, ¼ teaspoon salt, ¼ teaspoon garlic powder
In a bowl, combine the flaked salmon, chopped imitation crab, Japanese mayo, cream cheese, sriracha, soy sauce, sesame oil, green onion, and salt. Stir until creamy and well mixed, then taste and adjust spice as needed.

Press the rice into the bottom of a lightly greased 2.5-quart baking dish (9x9 or 11x7 dish) to form an even layer. Sprinkle a thin, even layer of furikake over the rice, then spread the salmon mixture evenly on top.
