Preheat your oven to 425°F (220°C) and place a wire rack over a large rimmed baking sheet lined with parchment paper.
Pat the chicken wings thoroughly dry with paper towels to ensure the skin becomes extra crispy during roasting.
In a large bowl, toss the wings with sea salt, black pepper, and garlic powder until every piece is evenly coated.
Arrange the wings in a single layer on the wire rack and bake for 35 to 40 minutes, flipping halfway through, until the skin is golden brown.
While the wings are finishing, combine the honey, tamari, grated ginger, and rice vinegar in a small saucepan over medium-low heat.
Simmer the sauce for 3 to 5 minutes until it thickens slightly into a glossy glaze, then remove from heat.
Transfer the hot wings to a clean bowl, pour the glaze over them, and toss immediately to coat.
Garnish with sesame seeds and thinly sliced green onions before serving warm.
