In a small bowl, whisk together soy sauce, honey, rice vinegar, sesame oil, minced garlic, grated ginger, and black pepper to make the glaze.
Pat the salmon fillets dry with paper towels and brush both sides lightly with olive oil.
Place the salmon fillets in a shallow dish and pour half of the soy sauce glaze over them. Let them marinate for 5 minutes at room temperature.
Preheat the air fryer to 400°F (200°C) for 3 minutes.
Place the salmon fillets skin-side down in the air fryer basket in a single layer.
Air fry the salmon for 10 minutes at 400°F (200°C), or until the salmon is cooked through and flakes easily with a fork.
During the last 2 minutes of cooking, brush the remaining soy sauce glaze over the salmon fillets.
Remove the salmon from the air fryer and let rest for 2 minutes before serving.
