ONO alchemy and S.T. Dupont Co-host "Hidden Garden Party" in Ginza

Japanese jewelry brand ONO alchemy will co-host an invitation-only event, "Hidden Garden Party," with S.T. Dupont at Mariage Frères Ginza Main Store for two days: July 12, 2026 (Sun) and July 19, 2026 (Sun).

At this event, we will introduce special edition collections, including S.T. Dupont's "Riviera," which has its roots in a bag created for Audrey Hepburn in 1953, as well as other leather goods and writing instruments from the maison, ahead of their general release. These collections will reflect ONO alchemy's aesthetic sensibilities.

The narrative embedded in ONO alchemy's jewelry, the craftsmanship inherited by S.T. Dupont, and the tea culture of Mariage Frères Ginza Main Store.

For two days, in a special space that unfolds beyond a hidden door, located in the heart of Ginza, these distinct aesthetic sensibilities will converge to paint a unique scene.

"Hidden Garden Party" Opens in Ginza

"Hidden Garden Party" is an event envisioned as a private garden-like experience, unfolding behind a door, right in the center of the urban metropolis of Ginza.

ONO alchemy's brand concept is:

"Boundary has no limit"

We view jewelry not merely as an accessory, but as an entity that brings courage and inspiration to the wearer's life, breathing new life into their stories.

This event will express that philosophy through the distinct aesthetics of jewelry, leather, and tea. The brand's background, the texture of materials, the aroma, conversations, and lingering impressions will all intertwine into a single, unified experience in a corner of Ginza.

Mariage Frères Ginza Main Store: The Venue

S.T. Dupont: Over 150 Years of History

S.T. Dupont is a French maison brand that began in 1872 when Simon Tissot-Dupont opened a leather goods workshop in Paris.

From its early days, the company focused on travel trunks and leather items, later expanding its creative scope to include lighters, writing instruments, and leather goods.

In 1953, André Dupont created the brand's first ladies' handbag, the "Riviera," for Audrey Hepburn. As a maison that cherishes the functionality, elegance, and the unique story of each owner inherent in its leather, it has passed down its craftsmanship for over 150 years.

At this "Hidden Garden Party," we will showcase the spirit of craftsmanship cultivated by the maison through a special edition collection that includes the "Riviera," symbolizing S.T. Dupont's history.

Special Edition Collections, Including the "Riviera"

This event will feature special edition collections of various items, including S.T. Dupont's "Riviera."

Created to commemorate the co-hosting of S.T. Dupont and ONO alchemy, this collection is a unique expression for this event, where the craftsmanship cultivated by S.T. Dupont resonates with the narrative that ONO alchemy has cherished in its jewelry.

Leather goods embodying S.T. Dupont's history and the narrative cherished by ONO alchemy will come together in one form. Starting from "Hidden Garden Party," these items will be presented as pieces that add new memories to the daily lives of their owners.

Founder's Comment

Emiri Kuwa, Designer/Founder of ONO Alchemy

With this "Hidden Garden Party," I wanted to create a time within the city of Ginza that feels like a private garden opening up behind a door.

As I create jewelry, I always ponder one thing: perhaps what truly moves people is not the completed beauty itself, but the time leading up to it, the memories at the moment of acquisition, and the life lived with the jewelry.

Leather gradually inscribes the owner's time as it is used. Tea offers a leisurely time to brew a cup, savor it, and converse. Jewelry, too, layers stories alongside the wearer's life.

Though seemingly different, I felt that all three are "things that beautifully store time." The craftsmanship S.T. Dupont has inherited through its long history and the sensibility ONO alchemy has cherished share common ground, and their respective aesthetics converge at the "Hidden Garden Party."

We hope that the items and experiences encountered in this secret garden will naturally blend into your daily lives and remain as beautiful memories in your hearts.
