Pat the chicken wings completely dry with paper towels to ensure maximum skin crispiness.
In a large bowl, toss the wings with arrowroot powder, sea salt, and black pepper until evenly coated.
Place the wings in the air fryer basket in a single layer, ensuring they are not touching to allow for air circulation.
Air fry at 400°F for 20-22 minutes, shaking the basket halfway through, until the skin is golden and crispy.
While wings cook, whisk together the toasted sesame oil, tamari, honey, minced garlic, and grated ginger in a small saucepan over medium heat.
Simmer the sauce for 2-3 minutes until it reduces slightly and becomes a sticky glaze.
Transfer the hot wings to a clean bowl, pour the glaze over them, and toss until every wing is well-coated.
Garnish the wings with sesame seeds and thinly sliced green onions before serving immediately.
