Fizz Or Sizz

Objective

Coca-Cola aimed to strengthen its brand association with food occasions in Japan by repositioning a familiar sensory cue—the fizz of the beverage—as a cultural moment. The campaign addressed an untapped pairing opportunity: Coke with karaage (fried chicken), a hugely popular dish that consumers didn't instinctively pair with the soft drink.

Solution

The campaign deployed a sensory guessing game spanning a week-long activation across radio, digital out-of-home billboards, and social media. Participants listened to audio clips and determined whether they heard Coca-Cola fizzing or karaage sizzling—sounds so similar that the distinction became a playful challenge. Correct guesses entered participants into daily drawings for free Coca-Cola products. The mechanic leveraged existing broadcast and digital infrastructure rather than a custom platform or app.
