A Closer Look at the Yamaha UX3 – Japan’s Premium Upright Alternative to a Grand
The Yamaha UX3 is part of Yamaha’s esteemed UX Series—performance-grade upright pianos that were sold exclusively in Japan and built for pianists who needed grand piano sound and responsiveness in a more compact form.
Introduced in the 1980s, the UX3 represents the pinnacle of Yamaha’s U-series evolution. Based on the U3 platform (52" tall), the UX3 was upgraded in nearly every way—designed for advanced players and institutions where space constraints made owning a grand impractical.
What Sets the UX3 Apart
Unlike standard U-series models, the UX3 includes several premium features:
X-Brace Back Frame
A defining feature of the UX Series, the X-shaped back post design significantly improves tuning stability and enhances sustain by reinforcing the structure of the piano more evenly than vertical posts alone.Premium Hammers and Soundboard Materials
Yamaha outfitted the UX3 with higher-grade hammer felt and carefully selected soundboard spruce—materials typically reserved for more advanced models. The result is a richer tone, greater dynamic control, and a more refined voicing palette.Grand Piano Characteristics in an Upright Form
Designed to serve players who couldn’t accommodate a grand, the UX3 delivers exceptional power, tonal depth, and responsiveness—making it ideal for serious practice, teaching studios, and performance settings.
A Japan-Only Model, Now Gaining Recognition Worldwide
Because the UX3 was never exported by Yamaha to the U.S. market, it remains rare and relatively unknown outside Japan. However, as more of these instruments are refurbished and imported, the UX3 is gaining recognition among pianists and technicians for its outstanding build quality and performance.
