Pat the chicken dry with paper towels (this will help them crisp up) and set aside.
In a small bowl, combine the soy sauce, brown sugar, garlic, and ginger. Set aside.
Heat the oil in a large skillet over medium-high heat. Add the chicken skin side down and cook for 4-5 minutes undisturbed. Reduce the heat to medium, flip, and continue cooking for 5-7 minutes until the chicken is cooked through. If there is a lot of fat in the pan, you can drain some of it.
Pour the sauce around the chicken and cook until it starts to bubble. Spoon the sauce over the top of the chicken and enjoy with a bowl of warm rice.
