September 4, 2025 /PRNewswire/ — The House of Harry Winston, renowned as the “King of Diamonds” and “Jeweler to the World,” is proud to unveil its new Ginza flagship store today.
It is Harry Winston’s largest flagship store in Japan, located at 1-7-10 Ginza, Chuo-ku, Tokyo, covering 869 square meters. This new three-story flagship store adopts a new design direction, reimagining the classic Winston style through a more modern architectural perspective.
Every detail within the store embodies Harry Winston’s rich history. Meticulously carved white polished marble outlines each floor. Custom-made carpets add warmth and texture. Walls are adorned with smooth white textured wallpaper and marble, creating a luminous effect. Unique chandeliers and carefully selected decorative furniture blend perfectly into the environment.
Each floor offers a distinct experience, guiding customers through a space that reflects the brand’s heritage and dedication to craftsmanship. The first floor is dedicated to bridal collections, while the second floor showcases classic collections, timepieces, and Harry Winston’s most exceptional high jewelry creations. This floor also houses Japan’s largest VIP salon, providing an intimate environment for private client experiences. The basement level features a dedicated concierge service for product maintenance, further enhancing the store’s after-sales service.
The exterior is clad in cream-colored travertine marble, featuring display windows and three illuminated light boxes showcasing the brand’s seasonal campaigns. At the entrance, Harry Winston’s classic black and gold double doors welcome guests. Adorned with a rosette motif and flanked by two matching lamp posts, these classic elements pay homage to the brand’s historic flagship store on Fifth Avenue in New York. Since opening its first boutique in Japan in 1988, Harry Winston has now expanded to eight boutiques across the country.
