Snap off tough ends of asparagus. Arrange 4 asparagus spears on a flat surface. Thread 2 (3-inch) skewers or toothpicks horizontally through spears 1 inch from each end to form a raft. Repeat procedure with remaining asparagus spears.
Combine soy sauce, oil, and garlic; brush evenly over asparagus rafts. Grill 3 minutes on each side or until crisp-tender.
Sprinkle evenly with sesame seeds, pepper, and salt.
