Combine first 6 ingredients, stirring with a whisk. Reserve 1/4 cup soy sauce mixture; cover and chill.
Combine pork and remaining soy sauce mixture in a large zip-top plastic bag; seal and marinate in refrigerator 2 hours or up to overnight, turning the bag occasionally.
Remove pork from bag, reserving marinade. Pour the marinade into a small saucepan, and bring to a boil. Cook 2 minutes. Thread 4 pork pieces onto each of 6 (12-inch) skewers. Thread 4 figs lengthwise onto each of another 6 (12-inch) skewers. Place pork brochettes on grill rack coated with cooking spray; grill for 10 minutes or until tender, turning and basting frequently with cooked marinade. Add fig brochettes to grill during the last 5 minutes of cooking time, turning once.
Place 1/4 cup reserved soy sauce mixture in a small microwave-safe bowl; microwave at high 2 minutes or until thoroughly heated. Serve with brochettes.
