KOHKOH Wins Prestigious Audience Award at New Jewelry TOKYO 2025

KOHKOH, a jewelry brand under Castem Co., Ltd., has received the Audience Award at the prestigious 'New Jewelry TOKYO 2025', held in Aoyama, Tokyo from November 28 to November 30. This marks the second consecutive year that KOHKOH has secured this acclaim, reinforcing its position in the jewelry industry.

The event, now in its 16th year, showcases around 130 brands, demonstrating the finest in designer jewelry. The award process features a stringent jury selection alongside public voting, highlighting the intimate connection between the audience and the artistry presented.

In an unexpected twist of fate, KOHKOH's creative vision struck a chord with the event's audience once again, thanks to the support of 712 public voters via the official New Jewelry TOKYO LINE account. Their recognition further endorses the brand's artistic journey and commitment to sustainable jewelry-making practices.

KOHKOH: Merging Artistry with Sustainability

Founded in 2023, KOHKOH is a beacon of innovation in sustainable jewelry design. The brand places a strong emphasis on eco-conscious practices and aesthetic value. By repurposing discarded mother-of-pearl—a byproduct of traditional pearl production—KOHKOH breathes new life into materials that would often go to waste.

Harnessing advanced 3D printing technologies, the brand has successfully challenged the conventional notion of pearls, introducing uniquely shaped pieces that captivate the eye and heart alike. This inventive spirit is bolstered by the expertise of Takushi Kojima, KOHKOH's designer and director, who has a rich background in jewelry artistry and education.

Perspectives from Takushi Kojima

Reflecting on this year's achievement, Kojima expressed immense gratitude for the audience's appreciation, stating, "Winning the Audience Award again validates our creative endeavors and reinforces the bond we have forged with our supporters. It is inspirational and a reminder of the responsibilities we hold to address social issues through our jewelry."

Looking ahead, KOHKOH is gearing up for its international expansion in 2026, with aspirations to reach a global audience. The brand remains resolute in its commitment to exploring how jewelry can serve as a medium for meaningful solutions to contemporary challenges.

Kojima's Creative Journey

Takushi Kojima is not just the face of KOHKOH; he is an established figure in the jewelry design community. He is known for running his own FACILE jewelry brand and for being a lecturer at Kobe Design University. Raised in an artistic family—his father a Nihonga painter and mother a craft artist—Kojima mingles traditional craftsmanship with contemporary art.

His career as a jewelry artist has spanned over 15 years, and he has gained recognition for exhibitions beyond Japan, including collections in Dutch, French, and Swiss museums. Kojima's profound dedication to redefining jewelry extends to collaborations within contemporary art realms, thus widening the scope of his artistic expression.
