In a large bowl, combine the soy sauce, sugar, ginger, sesame seeds, scallions, garlic and sesame oil. Add the chicken pieces and marinate at least 1 hour and up to 8 hours.
Light a grill or preheat a grill pan. Grill the chicken over moderately high heat, turning occasionally, until the chicken is lightly charred and cooked through, about 20 to 25 minutes. Transfer the chicken to a work surface and let rest for 5 minutes.
Meanwhile, in a small saucepan, bring the teriyaki marinade to a boil. Cook for 1 minute. Serve the chicken with the teriyaki sauce on the side.
The marinated chicken can be kept in the refrigerator for up to 8 hours before cooking. Bring to room temperature before grilling.
