IN 1 MINUTE
KitKat is one of the most frequently cited examples of international success in Japan. The usual interpretation tends to remain on the surface: regional flavours, limited editions or attractive packaging.
But the strategic interpretation goes much deeper.
In Japan, KitKat did not become established simply as a chocolate bar. It found a cultural function: becoming a small gesture of encouragement, especially during exam season. The phonetic similarity between KitKat and the Japanese expression kitto katsu —“you will surely win”— helped associate the brand with good wishes for students.
Another key cultural code was added to this: omiyage, the Japanese practice of bringing back gifts or travel souvenirs to share with family, friends or colleagues. KitKat Japan has developed regional flavours specifically designed as souvenirs.
This article was produced by LVS2 in collaboration with Nanako Akiyoshi, our local expert in communications and public relations in Japan. Her perspective provides first-hand insight into Japanese consumers and local cultural codes. At LVS2, we complement that perspective with a strategic interpretation for international companies seeking to enter, communicate or position themselves in Japan.
The lesson for an international company is clear: entering Japan is not simply about localising a product. It is about understanding the social role a brand can occupy within the market.
STRATEGIC QUESTION
The question we should be asking
When entering a new market, are we selling a product… or are we understanding the cultural gesture it could represent?
The mistake would be to focus only on flavours
When KitKat in Japan is discussed, its flavours are usually the first thing mentioned: matcha, sake, yuzu, wasabi, hojicha, strawberry, melon, purple sweet potato, regional editions and seasonal editions.
It is easy to stop there. But Japan cannot be understood through “unusual flavours”; it must be understood by observing the social function that an apparently simple object can acquire.
KitKat Japan’s own website presents its regional varieties as products linked to local ingredients, from Hokkaido to Okinawa, and as options designed to be taken home as souvenirs after a trip.
That detail is important, but it is not enough. KitKat’s success in Japan cannot be explained by variety alone, but by the brand’s ability to enter several cultural codes at the same time: good wishes, exams, gift-giving, travel, region, seasonality and attention to detail.
A chocolate bar that becomes a message
One of the best-known cultural codes is the association between KitKat and kitto katsu.
In Japanese, the expression can be understood as “you will surely win” or “you are sure to succeed”. That phonetic similarity helped KitKat become an informal good-luck charm for students before their exams.
What matters is not only the linguistic coincidence. What matters is that the brand found a way to become a message.
Rather than simply saying “buy chocolate”, it could express something more:
“I’m thinking of you.”
“Good luck.”
“I believe you can do it.”
That shift changes the value of the product. The chocolate bar ceases to be merely something to consume and becomes a gesture.
In Japan, where consideration for others, the appropriate way to express support and the value of small details are particularly important, that transformation has considerable strategic value.
LOCAL PERSPECTIVE
Nanako’s local perspective: when the gesture matters more than the object
Nanako confirms that KitKat is perceived in Japan as a small good-luck gift during exam season. She has given it to younger friends and family members herself, precisely because most Japanese people understand the association with kitto katsu.
Her interpretation adds an important nuance: although people know there is a marketing campaign behind it, the gesture is not perceived merely as advertising. It works because it fits a culture in which small details can express support, consideration and good wishes.
Drawing on her experience as a Japanese communications and public relations expert, Nanako also notes that some editions have used packaging reminiscent of Japanese good-luck charms. This reinforces the perception of a “charm” without making the product overly solemn. It remains light, accessible and everyday, yet culturally recognisable.
That is the difference. KitKat does not impose an external code; it finds a simple way to become part of a gesture that the market already understands.
When the channel also becomes part of the meaning
The KitKat Mail campaign took this logic one step further.
In 2009, KitKat and Japan Post launched a format that allowed the product to be sent like a postcard, with space to write a message of encouragement. The campaign drew on the association with kitto katsu and enabled family and friends to send good wishes to students before their exams. The product was sold through Japan Post and won the Media Grand Prix at Cannes Lions in 2010.
The strategic interpretation is clear: the brand did not merely use a word. It used a system made up of exams, family, a written message, post, gift-giving, a wish for success and a trusted institution.
Everything aligned. The channel was not simply a distribution point; it became part of the meaning.
Many foreign brands fail precisely here: they think about the message, but not about the system that makes that message feel legitimate.
The detail that changes perception: writing someone’s name
Nanako highlights another particularly important detail: around 2009, KitKat added a small space to the packaging where people could write the recipient’s name or a short message of encouragement.
That detail changes the nature of the product.
Normally, something bought in a convenience store or supermarket would not be perceived in Japan as a particularly meaningful gift. However, when someone writes a message, even a single KitKat can suddenly feel warm, personal and thoughtful.
The chocolate matters, but the gesture matters more.
The brand did not simply sell a product. It made it possible for someone to express support in a simple, socially accepted and easily shared way.
For a foreign company, this is probably one of the case’s greatest lessons: sometimes the strategic difference does not lie in radically transforming the product, but in adding the right gesture.
Omiyage: when a product represents a place
The second major cultural code is omiyage.
Nanako explains it clearly: omiyage is much more than a souvenir. It is a way of maintaining relationships. When someone travels, they are naturally expected to bring back a small local gift for colleagues, friends or family. It is a simple way of saying, “I thought of you”.
KitKat connected with that logic through its regional flavours.
A Hokkaido edition is not simply a variety. It is a way of bringing Hokkaido home.
An Okinawa edition is not simply a flavour. It is a way of sharing a journey.
KitKat Japan’s own communications present its regional varieties as flavours inspired by local ingredients and designed as souvenirs.
Therefore, the strategic question is not:
What local flavour can we create?
The question is:
What social function does that flavour fulfil within the market?
That is the difference between localising a product and reading a market.
What a foreign brand might misunderstand
At this point, Nanako’s contribution becomes especially valuable.
As she explains, many foreign companies focus on translating their products or incorporating Japanese visual elements, but they do not always understand the social context in which those products will be used.
That is precisely the risk.
Adding a Japanese word, a local flavour, a “Japanese” design or attractive packaging does not guarantee legitimacy.
Nanako stresses that another brand could not simply copy the idea of kitto katsu and expect the same result. One important reason is time. KitKat has been sold in Japan since 1973, following the licensing agreement signed by Fujiya and Rowntree-Mackintosh in 1972.
In other words, the brand was already familiar, well liked and recognisable long before the association with kitto katsu became widely known.
Had a newly arrived foreign brand launched a similar campaign from day one, it would probably have been perceived as a costly advertising slogan rather than an authentic gesture.
This is a central lesson for any international company: finding a good cultural idea is not enough. A brand needs legitimacy to activate it.
The dual perspective: Japan as a mirror for any international company
This case is not only relevant to companies that want to sell chocolate in Japan. It is relevant to any company seeking to enter a new market.
Because it raises an uncomfortable question:
Do we know what cultural function our brand could fulfil in that country?
In Europe, many companies think first in terms of attributes: quality, design, price, innovation, sustainability, technology or experience. All of that matters.
But in Japan, as in many markets, a brand’s value may also depend on how it becomes integrated into social gestures, consumption occasions, seasonality, gift-giving codes, professional relationships or indirect ways of expressing support.
A French company entering Spain should ask itself a similar question. The same applies to a Spanish company entering France, or an Asian company entering Europe.
Every market has objects, phrases, rituals and moments in which a brand can acquire a meaning greater than the product itself. The challenge is to identify them before communicating.
“KitKat did not simply localise a product. It found a cultural function.”
LVS2’s strategic interpretation
Nanako’s perspective allows us to read the case from within the Japanese market: how the gesture is perceived, which nuances make it work and why it cannot be copied mechanically.
LVS2’s strategic interpretation consists of translating those cultural codes into business decisions.
From the outside, KitKat Japan may appear to be a brilliant case of naming, regional flavours and packaging. However, from a market-entry perspective, it reveals something deeper: an international brand can grow when it does not try to impose itself as it is, but understands the cultural function it can occupy.
KitKat did not abandon its global identity. But in Japan, it found a specific function.
It went from snack to message, from product to gesture, from flavour to souvenir and from foreign brand to local reference point.
That transition does not happen by chance. It requires observing behaviours, decoding cultural codes, interpreting what they mean for a foreign company and turning that understanding into decisions about product, packaging, channel, message, timing and positioning.
Before asking how to sell in Japan, a company should ask itself:
What does this market need to express that our brand could help articulate?
That is a question of strategy, not translation.
LVS2 framework: understand the cultural function before communicating
Occasion
Which moments shape demand?
Exams, seasons, travel, celebrations, gifts, returning to work, family or professional life.
Gesture
What does the product enable people to express?
Support, luck, gratitude, consideration, status, care, belonging or remembrance.
Legitimacy
Does the brand have the legitimacy to occupy that role?
Adding local codes is not enough. The brand must understand whether it can become part of the ritual without appearing artificial.
System
Which channel validates the meaning?
In KitKat Mail, Japan Post was not merely a distribution channel. It was part of the message.
Decision
What needs to change before communicating?
Product, format, packaging, timing, channel, message or even the mental category through which we want to be understood.
Why should Japan be on the radar?
Japan is a demanding, sophisticated market that is difficult to read from the outside. Arriving with a good product is not enough.
Attention to detail, seasonality, the importance of gift-giving, the relationship between form and meaning, the role of trust and the precision of social codes lead many foreign brands to underestimate the work required before entering the market.
But precisely for that reason, Japan is an enormously valuable market from which to learn.
It forces companies to stop assuming that their way of communicating is universal. It forces them to read before acting and to ask what role their brand wants to play in people’s real lives.
Conclusion
KitKat did not become a success story in Japan simply because it launched different flavours. That is the visible part.
The invisible part is more interesting.
The brand found a way to become part of gestures of support, exam rituals, gift-giving culture, travel souvenirs and linguistic references.
And, as Nanako points out, that connection cannot be copied with a clever slogan. It requires time, familiarity, legitimacy and a genuine understanding of the gesture the brand wants to activate.
A market is not won simply by offering something. It begins to open when we understand what it means to offer something within that market.
And in Japan, as in any other country, that difference can change everything.
Frequently asked questions
Why was KitKat so successful in Japan?
Because of a combination of factors: regional variety, limited editions, gift-giving culture, the phonetic association with kitto katsu and the ability to become part of rituals such as exams.
What can a European company learn from this case?
Entering Japan requires an understanding of the cultural function a brand can occupy. Translating messages or launching a local version of the product is not enough.
Does the KitKat case apply to sectors beyond food?
Yes. The lesson is not about chocolate. It is about how a product can become a gesture, message, symbol or reference point within a market.
Can AI identify this kind of cultural opportunity?
AI can help identify general information, but interpreting which codes are relevant to a specific brand requires local expertise, strategic judgement and an understanding of the market.
About Nanako
Nanako is LVS2’s local partner in Japan and an expert in communications and public relations.
Her perspective brings first-hand insight into the Japanese market: how small gestures of support are perceived from within, the value of detail, omiyage, the importance of the right moment and a brand’s cultural legitimacy.
At LVS2, we complement that local perspective with a strategic interpretation for international companies: what a brand can learn from this case, which risks it should avoid and which decisions it should reconsider before communicating, positioning itself or launching a product in Japan.
This approach reflects our understanding of internationalisation: combining local knowledge, strategic interpretation and business insight to help brands make better decisions before entering a new market.
The conversation continues
At International Expert Insights, we do not analyse Japan as an exotic market.
We analyse it as a market that forces companies to ask better questions before making decisions: what to communicate, how to position themselves, which codes to understand, which channels to activate and which risks to avoid.
KitKat reminds us that a brand does not always grow by imposing its own meaning. Sometimes it grows when it understands the meaning the market is prepared to give it.
For any company seeking to enter Japan —or any country it does not yet know— the question is not simply which product it wants to sell.
It is what place the company can occupy in that market and which decisions it needs to make before communicating, investing or launching.
At LVS2, we support international companies during this initial phase: market analysis, entry strategy, positioning, communication and cultural adaptation.
Because before presenting itself in a new country, a brand needs to understand where it fits.
