Other forms: hibachis
A hibachi is a small, portable charcoal grill. You might bring a hibachi to a beachside cookout, along with some skewered meat and vegetables to cook on it.
Hibachi means "firepot" or "fire bowl" in Japanese, and in Japan it mainly refers to a small, charcoal-fired heater. For English speakers, a hibachi is used for cooking small amounts of food outdoors. The hibachis in Western restaurants are electric, but the kind a home cook uses is made from cast iron and has open grates over hot coals — and a Japanese speaker would call it a shichirin.
