Our Tumultuous Summer: ILLIT and Pocari Sweat's Declaration of a Generational Shift
Having worked in advertising for decades, I’ve come to realize that some brands sell the ‘season’ rather than the product itself. Pocari Sweat is one such brand. The colors, music, and expressions that naturally come to mind when summer arrives. The 2026 Pocari Sweat TVC Waiting ver., and its protagonist, ILLIT. This combination is not merely a change of models, but closer to a generational shift.
## Why ILLIT? The New Face of ‘Summer’
For a long time, Pocari Sweat has produced advertisements that served as a symbol of youth. Clear skin, white t-shirts, hair fluttering in the wind—that image has been repeated across generations.
ILLIT, selected this time, is a symbol of 5th-generation girl groups. They are a team that has formed a global fandom since their debut, showcasing both freshness and innocence simultaneously. They are the team best suited to express the ‘excitement of the opening scene’ that Pocari desires.
What I have learned on the advertising set is that if a face representing a generation is not replaced in time, the brand appears outdated. Pocari read that timing precisely.
## “Our Tumultuous Summer” – The Evolution of Copy
The keyword for this campaign is “Our Tumultuous Summer.” It is not simply ‘refreshingness.’ It is a word combining ‘blue’ and ‘tumultuous.’ It captures both emotion and color simultaneously.
If previous Pocari advertisements were closer to ‘pure youth,’ this copy is more dynamic. It conveys the message that summer is not merely a season of clear skies, but a time of turbulence, wavering, and growth.
From the perspective of an advertising planner, this represents an expansion of the brand’s worldview. While maintaining the symbolism of blue, it has broadened the spectrum of emotions.
## Waiting ver. – The Strategy of Waiting
This video is not the main feature, but the Waiting ver. It does not present a complete story. Instead, it throws out only the atmosphere and fragmented scenes.
In the advertising industry, this approach is called an ‘emotional teaser.’ It is a structure that leaves anticipation rather than explanation. The expressions of the ILLIT members, the wind, the sky, and the blue tones. Every element hints at summer, but it does not reveal the answer.
This approach is familiar to global K-culture fans because it follows the same grammar as comeback teasers. In essence, the advertisement has borrowed the structure of K-pop promotions.
## Visual Strategy – Maintaining Pocari’s Blue
In Pocari advertisements, blue is not just a color; it is the brand identity. This video, too, centers on blue tones that contrast with the blue sky and sea, as well as white outfits.
However, it is slightly different from before. It is softer and more lyrical. It feels as though the texture has been adjusted to match the image of ILLIT.
What I realized while working on this advertisement is that while maintaining the brand color, the tone must be adjusted. This campaign struck that balance well.
## The Intersection of Global Fans and Summer
Pocari Sweat is a brand that is synonymous with the "formula of summer" in Korea. However, with the emergence of ILLIT, this summer is becoming globalized.
K-pop fans do not view this advertisement as a simple beverage commercial. They consume it as another piece of content, as another expansion of the ILLIT worldview.
The moment the universal sentiment of summer meets the global culture of K-pop, the advertisement naturally transcends borders.
## An Advertising Expert's Conclusion
Watching this video, I thought to myself:
“Pocari has shifted generations once again.”
The brand remains the same. The blue color remains the same. However, the face and the texture of the emotion have changed.
What I have learned in my advertising career is that brands that last do not repeat themselves. Through ILLIT, Pocari Sweat redefines summer once again.
If you are a global K-culture fan, I hope you experience through this advertisement how Korea’s representative seasonal brand meets 5th-generation idols to create a new youth.
Summer always comes, but its face changes every time.
