On The Rocks Premium Cocktails and The House of Suntory Debut 'The Harmony Collection', a Limited-Edition Collaboration Crafted by Bartending Legend Hidetsugu Ueno

This special release blends Western cocktail traditions with the spirit of Tokyo's legendary bar scene — bottled for the first time

NEW YORK, April 17, 2025 – On The Rocks Premium Cocktails and The House of Suntory unveil The Harmony Collection — a limited-edition collaboration featuring two elevated ready-to-serve cocktails crafted by world-renowned bartender and proprietor of Tokyo's iconic Bar High Five Hidetsugu Ueno. The Yuzu Matcha Martini, made with Haku Vodka, and the Japanese Boulevardier, featuring Toki Suntory Whisky, elegantly infuse classic Western cocktail traditions with Ueno's mastery of Japanese bartending artistry.

A pioneer and master of modern Japanese mixology, Ueno-san is globally celebrated for his bespoke cocktails, meticulous and balanced craftsmanship, and expertise in ice sculpting. With The Harmony Collection, he brings his signature style to a ready-to-enjoy format for the first time — partnering with On the Rocks, the number one bartender-crafted bottled cocktail brand in the U.S., to deliver an authentic taste of Tokyo's cocktail culture in every pour.

"Cocktails are an art form — anchored in tradition, yet endlessly open to innovation," said Ueno. "With the Harmony Collection from On The Rocks Premium Cocktails, I was committed to capturing the precision, balance and artistry of Japanese bartending — bringing the spirit of craftsmanship to life in partnership with the number one bottled cocktail in the U.S. Each sip delivers an authentic, bar-quality experience and a true taste of Japanese culture."

The Harmony Collection captures the essence of balance—blending nature, culture and tradition through the lens of Japanese artistry. It unites The House of Suntory's premium spirits with On The Rocks' bartender-quality craftsmanship to deliver a seamless fusion of East and West in every bottle.

The result: two expertly crafted cocktails that showcase bold flavor and refined technique. The Yuzu Matcha Martini (20% ABV) layers bright, citrusy yuzu with the earthy depth of green tea, creating a vibrant yet delicate balance of tang and bitterness. The Japanese Boulevardier (32.5% ABV) reimagines the classic with a distinctly Japanese twist — infused with rich port wine and bitters for a bold, bittersweet profile that bridges old-world tradition and modern innovation.

"The Harmony Cocktail Collection is the first collaboration between On The Rocks Premium Cocktails and House of Suntory, bringing the essence of Japan to the U.S. and offering cocktail lovers a taste of Tokyo's world-class bar scene," said On The Rocks Premium Cocktails' brand ambassador Joaquín Simó. "By pairing premium Japanese spirits like Haku Vodka and Suntory Whisky Toki with expertly curated flavors, we're elevating ready-to-drink cocktails with a new level of sophistication and authenticity."

The On The Rocks Harmony Collection is available for a limited time in select markets nationwide, featuring two 375ml bottles in a convenient ready-to-serve two-pack for $29.99.
