1. Rinse chicken halves, and pat dry with paper towels. Place chicken cut side down in a 9x13 inch baking dish.
2. In a medium mixing bowl, combine sugar, soy sauce, grated ginger and garlic. Mix well, and pour mixture over chicken. Cover and refrigerate for at least 3 hours.
3. Preheat oven to 350 degrees F (175 degrees C).
4. Bake chicken uncovered in the preheated oven for 1 hour, basting frequently. Test for doneness, making sure there is no pink left in the meat. Let cool slightly, then cut into smaller pieces to serve.
