Preheat the oven to 400 degrees and line a baking sheet with parchment paper.
Pat the chicken wings dry with paper towels and place them in a large mixing bowl.
In a separate bowl, stir together the soy sauce, honey, balsamic vinegar, sesame oil, minced garlic, ground ginger, and black pepper until smooth.
Pour half the glaze over the wings and toss to coat evenly.
Arrange the wings in a single layer on the baking sheet and bake for 25 minutes.
Remove the sheet from the oven, brush the wings with the remaining glaze, and bake for 15 more minutes until the skin is crisp and the glaze has thickened.
Transfer to a serving plate and sprinkle with chopped green onions before serving.
