Iron Chef is a Japanese cooking competition featuring accomplished guest chefs challenging one of the show's resident " Iron Chef s" in a timed cooking battle built around a specific theme ingredient. The program has an eccentric flavor even for a game show. Its host is the flamboyant Takeshi Kaga, known on the show as Chairman Kaga. Its production values are highlighted with extensive commentary made by two regular commentators and one to two guest commentators (who also serve as judges). The commentary presents thorough background information (e.g., ingredients, past history of contenders) to give a viewer context for what is happening in the kitchen; it also serves as entertainment, as friendly banter is shared among the four commentators.
