There's provision for sprinklers (and has always been as far back as I go) for sprinklers in hoods. This is an alternative to CO2, or wet or dry chem, or any other acceptable protection method for commercial cooking hoods. Look at 13-10.Figure A.7.10.2. FYI: a hibachi in Japan is a box with charcoal that's placed under the table (think table at floor level with a hole under it for your feet and legs) that is then covered with a quilt that also covers the diners' legs and is used to keep the lower extremities warm during mealtimes on cold days (think paper walls and no heating system with snow outside). That morphed into a small table top grill similar to a Little Smokey but made out of cast iron (original hibachis were wooden boxes filled with sand). The grills used in a Beni Hana type teppan (cooking style type like stir fry or teriyaki or tempura)) restaurant is a flat grill and so by definition, for our purposes, is a flat grill cooktop and so falls into the hazard of grease in depth, along with deep fat fryers and tilting tray skillets. You cannot use sprinklers to protect this type of cooking surface unless listed for grease in depth. There has not been a head so listed since the early nineties. You can protect the ductwork and plenum areas with sprinklers but why would you when the chem system does that anyways? And if you use a rated and listed for fire protection, self-cleaning hood you don't need anything except for the surface chem system.
