The Kawai K-800 is the flagship upright piano in the K Series — often called an “upright grand” thanks to its commanding tone, refined design, and professional features. At 134 cm tall, it delivers concert-level dynamics, rich resonance, and power comparable to a baby grand, all within the space-saving form of an upright.

With Kawai’s advanced Millennium III Upright Action (ABS-Carbon composite), extended key length, solid spruce tapered soundboard, and full duplex scaling, the K-800 provides unmatched responsiveness and tonal clarity. A true sostenuto pedal, a grand-style music rack, and elegant cabinet design make this instrument the perfect choice for teaching studios, performance venues, and discerning pianists seeking the best in an upright piano.
