New Limited-Edition Harmony Collection of Premium, Ready-to-Serve Cocktails Includes Japanese Whisky Boulevardier.
On The Rocks™ Premium Cocktails and The House of Suntory have announced a collaborative launch titled The Harmony Collection, a limited-edition release of two ready-to-serve cocktails. Developed with Hidetsugu Ueno, the globally acclaimed bartender and owner of Bar High Five in Tokyo, the collection blends Japanese bartending artistry with classic Western cocktail influences.
Crafted by a Master of Japanese Mixology
Hidetsugu Ueno, recognized for his bespoke cocktails and precise technique, brings his craft to a ready-to-drink format for the first time. Known for his attention to detail and ice sculpting skills, Ueno partnered with On The Rocks, the top bartender-crafted bottled cocktail brand in the U.S., to introduce an authentic taste of Tokyo’s cocktail culture to a broader audience. “Cocktails are an art form — anchored in tradition, yet endlessly open to innovation,” said Ueno. “Each sip delivers an authentic, bar-quality experience and a true taste of Japanese culture.”

Introducing the Yuzu Matcha Martini and Japanese Boulevardier
The Harmony Collection includes two unique offerings. The Yuzu Matcha Martini (20% ABV) combines Haku® Vodka with the bright acidity of yuzu and the earthy notes of green tea. The Japanese Boulevardier (32.5% ABV) uses Toki Suntory Whisky™ and features port wine and bitters for a bold, bittersweet twist on the traditional cocktail.
Fusion of Premium Spirits and Bartender Expertise
According to On The Rocks’ brand ambassador Joaquín Simó, “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.” The collaboration showcases The House of Suntory’s premium spirits alongside On The Rocks’ reputation for bar-quality, ready-to-serve cocktails.

The Harmony Collection will be available for a limited time in select markets across the U.S. Each set includes two 375ml bottles, priced at $29.99. More information can be found at www.ontherockscocktails.com or via the brand’s social media channels.
