Chicken Nanban is a beloved Japanese dish that originated in Miyazaki Prefecture, located on the southern island of Kyushu. It was created in the 1960s as a casual eatery specialty and quickly became popular throughout Japan. Today, it’s a standard item on the menus of restaurants, izakaya pubs, and even bento shops.
What makes Chicken Nanban so unique is the combination of two irresistible elements: crispy fried chicken that’s briefly coated in a sweet-and-sour soy-vinegar glaze, and a generous topping of creamy tartar sauce. The result is an incredible balance of crunch, tang, and richness that keeps you coming back for more.
This recipe is designed to capture that same restaurant-style flavor and texture at home. The chicken stays juicy inside with a crunchy coating, and the homemade tartar sauce—enhanced with just a touch of sesame oil—takes it to the next level.
It’s a family favorite in our home, and I hope it will become one in yours too!

Tips & Notes
・For the tartar sauce, use a hard-boiled egg that was cooked for about 10 minutes. ・When marinating with B, coat the chicken quickly and pour any remaining marinade over the top before cooking. ・Great for bento lunch boxes. ・Freezer-friendly: you can freeze the fried chicken without the sauce.
