KFC’s new Japanese-Style Summer Burgers source refreshing ingredients from Setouchi and Wakayama

Jul 14, 2025

Things are looking pretty sweet for fans of fried chicken and Japan’s citrus stars.

Japan’s summer is feeling a little lacking in its Japanese-ness in some ways this year, but it’s set to get a little boost in that regard from the unexpected source of KFC. Later this month, the Kentucky-born, big-in-Japan chain will be releasing a pair of new Japanese-Style Summer Burgers, or, if you’re really getting into the Japanese-style spirit, the Natsu no Wafu Burgers.

First up is the brand-new Negishio Lemon Chicken Filet Burger. The “chicken fillet” part is something you can probably already envision, but negishio refers to a kind of traditional Japanese sauce/dressing made from diced green onion (negi), salt (shio), and sesame oil. The lemon sauce here has a Japanese aspect to it too, as KFC sources the fruit it uses from West Japan’s inland sea-adjacent Setouchi region, which produces some of the finest citrus fruit in the country.

The other Japanese-Style Summer Burger, the Chicken Nanban Fillet Burger, is making a return to KFC’s menu after its debut last summer. Chicken nanban is a dish that originated on Japan’s southwestern island of Kyushu, taking inspiration from the cooking styles brought over by Portuguese traders during Japan’s feudal era. The key ingredient is a creamy tartar sauce-like condiment with sour accents from vinegar and, in the case of KFC’s Chicken Nanban Fillet Burger, a citrus infusion.

Even the sides and drinks are getting a shot of Japanese citrus flavor, with a new Salty Setouchi Lemon powder to shake onto KFC’s French fries

…and a natsumikan mandarin orange lemonade soda that gets its oranges from Wakayama Prefecture, among Japan’s best mandarin growers.

The Japanese-Style Summer Burgers are priced at 540 yen (US$3.75) each, the fries with Setouchi lemon powder at 320 yen, and the Wakayama mikan soda at 300 yen. They all go on sale July 16 and will be available for a limited time.
