Combine the teriyaki sauce/marinade ingredients except the cold water and corn starch together and divide it in half and set one half aside.
Toss the other half of the marinade with the salmon to fully coat. Marinate for about 30 minutes to an hour—can be marinated up to about 8 hours.
Once marinated, add the salmon bites to air fryer basket in a single layer. You can work in batches if needed. (I do not preheat my air fryer, but you can if preferred, cook time may be a bit less).
To Air Fry: Set air fryer to 400°F and air fry for about 7-10 minutes, turning or shaking halfway through is optional. Salmon is ready when the outside is brown and crisp and the internal temperature reads 145°F or desired doneness.
To Bake: Preheat oven to 400°F. Arrange the marinated salmon bites on a parchment paper lined baking sheet. Bake for about 12-15 minutes or salmon is cooked through.
While the salmon cooks, prepare the teriyaki sauce: Whisk together the corn starch and water until corn starch is dissolved and stir it into the reserved marinade. Transfer to a small sauce pan and heat on medium until thickened. If it becomes too thick, add a splash of water to thin it out.
Once the salmon is cooked, transfer it to a serving dish and toss it with the heated teriyaki sauce. (you can alternately drizzle the sauce over the salmon in the rice bowls—either is great!)
Assemble the rice bowls, drizzling any remaining teriyaki sauce over the salmon and serve!
