Sekkisei Launches New Winter Campaign Featuring Number_i

Kose Corporation, headquartered in Tokyo, is proud to unveil its latest winter season television commercial for its prestigious skincare brand, Sekkisei. The new ad campaign, titled "i Bright. - More Transparent than Snow -" will debut on November 13, 2025.

Starring the globally recognized artist group Number_i—comprising Sho Hirano, Yuta Jinguji, and Yuta Kishi—the commercial transports viewers into a breathtaking silvery world resembling a winter wonderland, where the trio embodies the purity and crystalline clarity that defines Sekkisei's essence.

In this captivating new campaign, the members of Number_i express their excitement by noting how well they relate to the skincare products being showcased, namely the hydrating lotion, emulsion, and cream from Sekkisei's "Medicated Brightening Series." They shared, "Each one of us has unique strengths, but when combined, we become even stronger—just like the trio’s synergy!" Their synergy is a beautiful representation of the harmony between the products and their personal camaraderie.

Since its initial introduction last November, Sekkisei’s "i Bright." campaign continues to build on its success. The first installment featured a partnership with the group’s song "iLY," while the second chapter used the track "Romijuri." Now, the third installment tells a story of winter’s unique beauty and freshness, accentuated by the ethereal sounds of their piece titled "i," included in the Mini Album "No.O -ring-."

Jinguji expressed his enthusiasm, saying, "Given that Sekkisei has 'snow' in its name, we've truly waited for this opportunity!" The commercial’s wintry visuals are further enlivened by the members wearing all-white outfits against the backdrop of softly falling snow, creating a serene atmosphere of beauty and tranquility.

In stunning imagery, Number_i is shown interacting with the snow—each delicate flake melting away upon contact, embodying the fleeting yet beautiful nature of winter. The CM is paired with ambient lyrics conveying an uplifting sentiment, making it an ideal fit for the holiday season.

Hirano reflected, "We really became a part of this magical winter world, linking our presence with Sekkisei's products—the lotion, emulsion, and cream. We aimed for a pure freshness that transcends even snow itself!" Likewise, Kishi added that they strived to achieve such clarity that they’d almost appear to vanish, blending beautifully with their sparkling surroundings. Their unique expressions and enchanting appeal are sure to resonate with audiences.
