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.


The ST-1 Institutional Piano is a powerhouse performer for institutional settings. Its exclusive Millennium III Upright Action features ABS-Carbon parts that are incredibly strong and lightweight — properties that allowed our engineers to optimize speed, repetition, power and control. Its five sturdy back posts measure 80mm x 80mm for maximum rigidity and stable tuning.

The 47″ raised music rest is the longest on any institutional piano — perfect for sheet music that extends laterally. Longer keys provide more consistent touch response. A stylish reinforced bench is made to last longer than conventional benches. And its “Soft Fall” Fallboard closing system protects hands and the piano’s finish from the harm that jarring close might cause. With all these valuable attributes and many more, the ST-1 is the ultimate blend of performance and durability.
