Combine Kewpie mayonnaise with lemon juice and mix well.
If your salmon has the skin on, place it skin side down and evenly spread the lemon-mayo over the top of the salmon fillet.
Sprinkle furikake over the mayonnaise generously.
Place salmon directly onto your air fryer rack or basket. Air fry at 350°F for 12 minutes or until the thickest part is fully cooked.
If you're using an oven or toaster oven, place the salmon on the rack of a roasting pan or foil-lined baking sheet. Bake at 375°F for 15 minutes or until the thickest part is fully cooked.
Drizzle Furikake Salmon with teriyaki sauce and a squeeze of lemon.
