The Kawai ST-1 is everything an institutional piano should be – amazingly strong, exceptionally playable, and built to last. It combines the world's most advanced upright piano action with many new design enhancements that allow it to outperform every other piano in its class. For institutional settings that demand consistently high performance amid the rigors of heavy use, the Kawai ST-1 is the ideal choice.

Compared to its predecessor, the UST-9, the ST-1 benefits from several consumer-focused improvements that make it more fitting for homes while not sacrificing anything for institutions. Namely, thicker back posts, longer 47" music desk, stylish reinforced bench, longer keys, a “Soft Fall” fallboard closing system, and a practice pedal.  

It uses the exclusive Millennium III Upright Action with ABS-Carbon parts that are incredibly strong and lightweight — properties that allowed Kawai engineers to optimize speed, repetition, power and control. This is the same award-winning action featured in the K Series Professional Upright pianos too.

The ST-1 is the ultimate blend of performance and durability. It's truly a powerhouse designed well for institutional settings with fine material choices and engineering. The sound is loud and versatile. The feel is second-to-none. The construction is high-end. The feature set is full. And to absolutely guarantee peace of mind, the ST-1 is covered by a Ten Year Fully Transferrable Manufacturer's Warranty -- the seal of Kawai craftsmanship and assurance of your satisfaction for years to come.

  • Award-winning Millennium III Action made with new ABS-Carbon material: the most consistent, reliable and dynamic action on the market
  • Large solid select-spruce soundboard supported by thick ribs, laminated back posts, nose bolts, and "matched strength" iron plate results in a strong and soulful sound, sure to last decades longer than traditional soundboard designs 
  • Composite-material action + cross-laminated pinblock and backposts = a durable piano that'll last decades to come and cost less to maintain
  • Tons of features suited for institutional use such as long music desk, soft-close fall board, lid-fallboard locking mechanism, rubber casters, Cast Brass pedals, practice pedal, and reinforced bench
