Pat the chicken wings completely dry with paper towels to ensure maximum 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.
Air fry at 400°F (200°C) for 18-20 minutes, flipping halfway through, until the skin is golden and crispy.
While the wings cook, mince the garlic and grate the ginger.
In a small saucepan over medium heat, combine honey, tamari, garlic, ginger, rice vinegar, and sesame oil.
Simmer the sauce for 2-3 minutes until it thickens into a glossy glaze.
Transfer the crispy wings to a clean bowl, pour the glaze over them, and toss to coat thoroughly.
Garnish with thinly sliced green onions and serve immediately.
