Preheat oven to 400°F and line a large baking sheet with parchment paper for easy cleanup.
Pat the chicken wings with paper towels until they are bone-dry and, if not already split, separate them into flats and drumettes.
In a large bowl, toss the wings with arrowroot starch, sea salt, and black pepper until every piece is lightly and evenly coated.
Arrange wings on the prepared sheet in a single layer and bake for 35-40 minutes, flipping halfway through, until the skin is golden brown and crispy.
While wings bake, whisk together honey, tamari, minced garlic, grated ginger, and sesame oil in a small saucepan over medium-low heat.
Simmer the glaze for 4-5 minutes until it reduces into a thick, glossy sauce that easily coats the back of a spoon.
Transfer the crispy wings to a clean bowl, pour the warm honey-garlic glaze over them, and toss until every wing is thoroughly coated.
Garnish with freshly sliced green onions and serve immediately while the wings are hot and the glaze is sticky.
