Toriten

Originated in Beppu, Oita prefecture, at Toyoken, a Chinese restaurant opened in 1926 by Miyamoto Shiro, a French-trained chef who had worked at Tokyo's Imperial Hotel. In the early Showa era he adapted a Chinese fried-chicken dish into a Japanese style, slicing tough local chicken thin and frying it in tempura batter; it first appeared on the menu under an older name before becoming known as toriten. Oita prefecture officially designates toriten as its regional dish; the city of Beppu hosts an annual toriten festival. Spread across Kyushu in the 1980s; reached Tokyo only in the 1990s.

Beppu, Oita 1962 invention at Toritenya by Asai Akio — chicken in tempura batter because Oita had birds, not the coastal fish. Soy-ginger pre-marinade is what makes it toriten and not bland tempura chicken.

Boneless chicken thigh in a light tempura batter, fried until the coating is pale and crackly — not the dark, heavy crust of karaage. Served with a small bowl of ponzu (citrus-soy) and grated daikon, sometimes Japanese mustard on the side. The batter is barely seasoned; the chicken inside is marinated in soy and ginger so the flavor reads through. Eaten as part of a teishoku, or alone with shochu.

The batter difference is the whole point. Karaage uses potato starch dredge for a thick crackly shell that holds for hours; toriten uses thin tempura batter (cold water, low-protein flour, lumpy on purpose) that produces a delicate crust meant to be eaten in the first 5 minutes. Marinating the chicken before battering is non-traditional in tempura — toriten breaks that rule because plain tempura chicken is bland; the soy-ginger pre-soak makes the meat taste seasoned before it hits the dipping sauce.
