Preheat oven to 425°F (220°C) and line a baking sheet with parchment paper.
Pat the chicken wings completely dry with paper towels to ensure maximum crispiness.
In a bowl, toss wings with sea salt, black pepper, and arrowroot powder until evenly coated.
Place wings on the prepared baking sheet in a single layer and bake for 30-35 minutes, flipping halfway, until golden and crispy.
While wings bake, whisk together honey, tamari, rice vinegar, toasted sesame oil, minced garlic, and grated ginger in a small saucepan.
Simmer the sauce over medium-low heat for 3-5 minutes until it thickens into a sticky glaze.
Once wings are done, transfer them to a large bowl, pour the glaze over them, and toss to coat thoroughly.
Garnish with sliced green onions and serve immediately.
