Karaage might be the most widely eaten fried chicken style in Asia. It is fundamentally different from Western fried chicken: smaller pieces, a soy-sake-ginger marinade rather than buttermilk, and a coating of potato starch (katakuriko) rather than seasoned flour. The result is lighter, crispier and more intensely flavoured. The deep-fried version is the original and best; the air-fried version is a serious contender for weeknight cooking.
The marinade is what distinguishes karaage from other fried chicken. It does two things: flavours the meat and tenderises it slightly via the ginger enzymes and sake. Do not skip it or shorten the time - 30 minutes is the minimum, 2 hours is better, overnight is excellent.
Marinade for 500g chicken:
Combine in a bowl, add chicken, mix to coat, cover and refrigerate. The marinade makes a noticeable difference - karaage without it produces acceptable fried chicken, not the real thing.
Potato starch (katakuriko) is the traditional coating. It produces a lighter, crispier result than flour because it gelatinises differently at frying temperatures. Cornstarch is the best substitute; all-purpose flour produces a heavier crust. Most Asian grocery shops stock potato starch; it is increasingly available in larger supermarkets.
Some recipes use a 50/50 mix of potato starch and flour - this produces a sturdier crust that holds up better in bento boxes (the crunch survives longer). For eating immediately, pure starch is better.

Remove chicken from marinade. Toss thoroughly in potato starch until evenly coated. Shake off excess.
Heat oil to 170°C / 338°F in a deep saucepan or wok - enough oil to submerge the chicken pieces. Fry in batches (no crowding - temperature drops significantly) for 3-4 minutes until pale golden. Remove and drain on a rack.
Once all pieces have been fried once, heat oil to 190°C / 375°F and fry each piece again for 1 minute. This double-fry is what gives karaage its distinctive crackling exterior. The first fry cooks the chicken through; the second fry drives out moisture and crisps the coating.
Serve immediately with wedges of lemon and Japanese mayonnaise (Kewpie).

Coat the marinated chicken in potato starch as above. Spray the air fryer basket with oil. Arrange pieces in a single layer - do not stack. Spray the tops of the chicken lightly with oil.
Cook at 200°C / 400°F for 10-12 minutes, flipping halfway, until golden and the internal temperature reaches 75°C / 165°F. The crust will be crisp but not identical to deep-fried - it lacks the shattering quality of double-fried karaage. For a bento box, this difference matters less.

The least crispy of the three methods but still acceptable. Preheat oven to 220°C / 425°F. Place coated chicken pieces on a wire rack over a baking tray - the rack allows air to circulate underneath. Brush or spray with oil. Bake for 18-20 minutes, turning once, until cooked through and golden. The crust will be less crackling than fried versions but the marinade flavour comes through fully.
Karaage is traditionally served with:
Karaage is best eaten fresh. If making ahead, deep-fry once only (the first pass), cool and refrigerate. Finish with the second fry just before serving. Air-fried karaage reheats adequately in an air fryer at 180°C for 3-4 minutes.
