Prepare the shrimp marinade by combining the garlic, ginger, teriyaki sauce, clamato juice and lemon juice.
With scissors, cut the shrimp shell and remove the black vein. Leave the shell on. Put shrimp in a large bowl and cover with the marinade. Marinate for about 1/2 hour before grilling.
Preheat the barbeque to medium. Grill shrimp for 1 minute then turn over, cover the grill and cook for another 2 minutes.
