F.D.C. Products Co., Ltd., operator of the jewelry brand 4℃, is teaming up with Hibiya Kadan for an in-store event called "4℃ Ginza Main Store x Hibiya Kadan -Jewelry meets Flower-" at 4℃ Ginza Main Store.
This second edition runs for nine days, from Saturday, August 1 to Sunday, August 9, 2026. Visitors can enjoy a relaxed moment with the jewelry inside a shop decorated with seasonal flowers, and further editions are planned for autumn and winter.
The collaboration grew out of a wish to let visitors enjoy the jewelry in a refined space filled with flowers of the season, wrapped in the rich scent of fresh blooms as the flowers and jewelry play off one another. A popular florist from Hibiya Kadan is handling the in-store floral displays. For this second edition, sunflowers that shine in the summer sun take center stage, arranged with yellow and orange blooms for a sophisticated, urban atmosphere.
During the event, customers who follow the official Instagram account of 4℃ Ginza Main Store or try on jewelry in the shop will receive a single flower as a gift. Bridal items are included in the offer, and customers who make a reservation in advance through the official website can be guided through the shop more smoothly.
