Introducing a new generation of upright pianos
For over 85 years, Kawai has been building pianos, pioneering the use of state-of-the-art materials and innovative technology to advance the piano. Our experience and long tradition of craft allows us to create pianos with outstanding touch and tone and the performance features for tomorrow.
Kawai’s patented Millennium III upright action is the secret behind the ultra-responsive touch of the K Series. Introduced in 2006, Millennium III has components made of ABS-Carbon, a composite material created by the infusion of carbon fibre into ABS Styran. ABS-Carbon is incredibly sturdy and rigid, which allows us to create action parts that are lighter and stronger.

What makes a K Series upright piano?
Our exclusive NEOTEX key surface material made with cellulose fibre offers the smooth texture of natural ivory and ebony – and a semi-porous, silica filled surface to absorb the hand’s natural oils and perspiration that can cause slipping. NEOTEX resists cracking and fading over years of use. It is used for both the sharps and the naturals for a consistent feel across the entire keyboard.
The soundboard is the heart of a piano. Its purpose is to transform the vibrations of the piano’s strings into a rich, resounding tone. Kawai uses only straightgrained, quarter sawn solid spruce for K Series soundboards. Each soundboard is strategically tapered to maximise its tone producing capability. Only those that meet or exceed our demanding quality standards are selected for use in our professional upright pianos.
The piano’s soundboard is placed under tension to create a slight curvature – or crown – that dramatically increases the production of sound. K Series pianos feature full length ribs that are securely notched into the rim liner on all sides to preserve the soundboard crown over time. The ribs also distribute sound energy more evenly across the soundboard to optimise its tone producing capabilities. Contour bars reshape the speaking area of the soundboard to resemble the contour of a grand piano soundboard, while reflecting sound energy back into the centre for increased tonal power and sustain.
All K Series hammers are T-stapled to preserve hammer shape, and fitted with an added interior layer of underfelt to support the creation of exceptional tone. Bridges transfer the vibrations of the strings to the soundboard. K Series bridges are made from select hard maple, individually notched for a clear, powerful tone quality. Height is carefully set and matched to the iron plate for correct string pressure and optimal tonal transfer.
Harnessing today’s technology for tomorrow’s pianos
Kawai’s proprietary casting process binds molten brass to a steel core in strong, beautiful pedals that will not wear through over time. K Series front casters made of solid brass are as sturdy as they are attractive, with double casters used for the larger K Series models (from K-300).
As functional as they are beautiful, K Series upright pianos include a long list of inspired features designed to ensure effortless practicality. The ultra-slow ‘SoftFall’ closing system protects hands and the piano’s finish from the harm that a jarring close might cause. Conveniently built into the fallboard, selected K Series music racks extend 100cm to accommodate multiple music books or sheet music that extends laterally.
The height adjustable bench on all K Series models is ideal for teaching studios with many students and for families with more than one player.
