Rinse 1 cup uncooked sushi rice with cold water until the water runs clear.
Cook the rice on the stovetop, in a rice cooker, or in the Instant Pot. If you use a rice cooker or Instant pot, cook the rice according to the instructions on the package. Mine called for 1 ¼ cup water for the 1 cup of rice.
While the rice is cooking, add 2 tablespoons seasoned rice vinegar, 1 tablespoon granulated sugar, and ¼ teaspoon salt to a small bowl and heat it in the microwave for 30 seconds, then stir it until the sugar has dissolved.
Transfer the cooked rice to a large mixing bowl and pour the vinegar mixture over it. Stir until the rice is evenly seasoned. Set the bowl aside and let the rice cool to room temperature.
Assembly
Preheat the oven to 425 degrees Fahrenheit and spray a 9-inch or 2-quart baking dish with nonstick cooking spray and set aside.
Use a fork to shred 8 ounces imitation crab until stringy, then chop into pieces about an inch long. Flake 8 ounces cooked salmon with a fork.
Add the flaked salmon, shredded crab, 3 ounces softened cream cheese, ⅓ cup Kewpie mayonnaise, and 2 tablespoons sriracha to a large bowl and mix until combined.
Press the cooled rice into the bottom of the baking dish. Crush 1 (1.17-ounce) package nori sheets over the top of it so the rice is evenly covered, adding more or less as desired.
Spread the salmon and crab mixture over the top of the nori. Bake for 15-18 minutes, until thoroughly heated through.
Drizzle the top with sriracha, spicy mayonnaise, and eel sauce (Unagi sauce). Garnish with sesame seeds, sliced green onions, and chopped cilantro, and serve immediately.
