Preheat your oven to 400°F and line a large baking sheet with parchment paper for easy cleanup.
Pat the chicken wings thoroughly dry with paper towels to ensure the skin becomes crispy during roasting.
In a large bowl, toss the wings with sea salt, black pepper, and garlic powder until evenly coated.
Arrange the wings in a single layer on the prepared baking sheet and roast for 35 to 40 minutes, flipping halfway through.
While the wings are in the oven, combine the honey, tamari, sesame oil, and ground ginger in a small saucepan over low heat.
Simmer the sauce for 3 to 5 minutes, stirring constantly, until it thickens into a glossy glaze.
Remove the roasted wings from the oven and transfer them to a clean bowl, then pour the warm glaze over them and toss well.
Transfer to a plate and garnish with toasted sesame seeds and thinly sliced green onions before serving.
