Nestlé Japan turns KitKat's pun into an exam charm — 34% of teens call it omamori
KitKat sounds like 'kitto katsu' ('surely win'); Nestlé Japan made the bar a juken lucky charm, 5 million bars a day

What it had to solve
KitKat sold poorly in Japan for decades until local managers noticed Kyushu students were buying bars as good-luck gifts during the December–February exam season.
How it works
KitKat arrived in Japan in 1973 as a British import and sold poorly for years. Around the late 1990s, students on the island of Kyushu noticed the candy's name sounded like 'kitto katsu' — 'you will surely win' — and began giving bars to friends before university entrance exams.
Sales spiked in Kyushu every December to February, juken season. Two Nestlé Japan managers, Masafumi Ishibashi and Kohzoh Takaoka, leaned into the accident: from 2003 the company ran exam-support campaigns, free bar handouts, punning ads and special packaging with a blank panel for handwritten encouragement.
The association became a national ritual. In January 2003, 34% of Japanese teenagers told pollsters KitKat was their favorite good-luck charm, second only to a genuine Shinto omamori. Japan grew into the brand's biggest market, consuming about 5 million bars a day, and the 'Lucky Charm' campaign won an Asian Brand Marketing Effectiveness Award in 2005.
Why it lands
- It started from observed consumer behavior — a regional sales spike — instead of a strategy imposed from headquarters
- The pun gave the brand a local, emotional meaning that imported British advertising never had
- Packaging with a message space turned a candy bar into a gift and a ritual object
- A single cultural hook (exam luck) was cheap to keep renewing every January, season after season
What it did
In January 2003, 34% of Japanese teenagers named KitKat their favorite good-luck charm, second only to a shrine omamori. Japan became the brand's biggest market at roughly 5 million bars a day, and the 'Lucky Charm' campaign won the Asian Brand Marketing Effectiveness Award in 2005.
What you can take
Don't fight a meaning your customers invented — invest in it. Nestlé built packaging, ads and distribution around wordplay that began as student gossip, and a stalled brand became a ritual.
Since then
Nestlé Japan kept building on the exam-charm identity: a 2009 tie-up with Japan Post let people mail KitKats with notes from 20,000 post offices, and hundreds of thousands of bars were sent to students. The brand also became Japan's regional-flavor machine — strawberry, matcha and dozens of rotating local varieties — and tourists carried them home as souvenirs, turning a lucky-charm habit into a national confectionery institution.
