Japan — jidori breed traditions by prefecture; Hinai-jidori from Akita; Nagoya Cochin from Aichi
Japanese premium chicken culture distinguishes between commercial chicken (bura-iler) and jidori (地鶏, literally 'local bird') — heritage breed, free-range, slowly grown chickens with firm, intensely flavoured flesh and high fat content that contrasts dramatically with commercial chicken. The legal designation 'jidori' in Japan requires: a native Japanese breed (or cross); free-range raising; low density (1 bird per 3.3m²); slow growth minimum 75 days (vs 45 days commercial); and no growth promoters. Major jidori breeds: Nagoya Cochin (the most famous — from Aichi, dense flavour, high fat); Hinai-jidori (from Akita Prefecture — the most expensive, often described as Japan's finest chicken); Satsuma-jidori (from Kagoshima — assertive flavour for yakitori); Miyazaki Chicken (increasingly prized). Shashu chicken (from 'sha-sha' flying game birds) is used in yakitori for its particularly firm muscle texture from extensive exercise. The jidori movement has driven a renaissance in yakitori culture.
Firm, dense, intensely chicken-flavoured with rich fat; completely different from commercial chicken's mild, soft character; jidori skin is particularly flavourful with high-fat crispness; the chicken flavour in broth is extraordinary
Jidori must be cooked differently from commercial chicken — the higher density and less fat-marbled breast means it can be served medium (with the breast barely cooked through) while the thigh is best at medium to medium-well; jidori skin is particularly prized in yakitori — the higher fat content renders more slowly and creates crispier, more flavourful skin; the firm texture of jidori muscle makes it excellent for tataki (briefly seared) preparations.
Hinai-jidori kiritanpo-nabe (from Akita) is considered Japan's most satisfying chicken hotpot — the bird's extraordinary flavour combined with kiritanpo (moulded rice on cedar skewers) and seasonal vegetables in a pure chicken broth is the pinnacle of this tradition; jidori yakitori at specialist Tokyo restaurants (Torishiki, Yakitori Imai) uses single-breed jidori for each cut — the difference from commercial chicken yakitori is immediately apparent; Nagoya Cochin oyakodon (parent-and-child rice bowl — chicken + egg) uses both the Nagoya Cochin chicken and its eggs for a single-breed experience.
Cooking jidori exactly as commercial chicken (jidori's more complex flavour benefits from lighter cooking — overcooked jidori, unlike commercial chicken, does not become soft but instead becomes very dry and tough); ignoring the skin (jidori skin has exceptional flavour — it should be served separately at yakitori restaurants as kawa-yaki); using jidori in heavily sauced preparations that mask its delicate flavour.
