Scientific Innovation Meets Musical Artistry
Discover the cutting-edge technologies that make Kawai pianos the choice of competition winners, concert artists, and discerning musicians worldwide. Each innovation represents years of research, testing, and refinement.
Pioneering Piano Technology
From revolutionary composite materials to advanced digital sound processing, Kawai's technologies set new standards for piano performance, reliability, and musical expression.
Millennium III Action
The heart of a Kawai is its action — and Kawai builds it differently. The Millennium III action is engineered from ABS-Carbon composite: the same class of material trusted in the Boeing 787, Formula 1, and elite bicycles, chosen for one reason — more strength and stiffness at less weight. The result is a touch that is faster, more durable, and more stable than any wooden action, season after season.
What You Touch
Neotex Key Surfaces
The ABS-Carbon composite is inside the action. The keys under your fingers are finished in Neotex — Kawai’s exclusive cellulose-fiber key surface with the understated texture of natural ivory and ebony. Its semi-porous, silica-filled finish absorbs the hand’s natural oils and perspiration for a secure grip through the most demanding passages, resists cracking and fading over decades, and stays static-free to shed dust.
- Ivory-and-ebony feel, on both naturals and sharps
- Absorbs moisture for a secure, slip-free touch
- Resists cracking, fading, and static over years of play

Composite, wood, and what your fingers actually feel
The questions pianists ask before choosing a Kawai — answered plainly.
Is a composite piano action as good as a wooden one?
- Better, in the ways that matter for playing. Kawai’s ABS-Carbon action parts are over 50% stronger and more durable than conventional wood, transfer more energy to the hammer, and make the Millennium III grand action about 25% faster. Because they don’t absorb moisture, they hold their precise regulation season after season — where wooden parts swell, shrink, and drift out of adjustment.
Will a Kawai action feel like plastic?
- No. Pianists consistently describe the Millennium III touch as fast, even, and grand-like. "ABS-Carbon" refers to what the internal action parts are engineered from — not the playing surface. The keys you actually touch are finished in Neotex, a cellulose-fiber surface with the understated texture of ivory and ebony that absorbs moisture for a secure grip.
Does the composite action hold up in humidity?
- Yes — that is one of its biggest advantages. Traditional wooden action parts expand and contract with humidity, altering the fine geometry of the action. ABS-Carbon does not shrink or swell, so a Kawai keeps its factory-set touch and repetition in climates and seasons that force frequent regulation on all-wood actions. The stability was independently confirmed in testing at Cal Poly.
Is carbon fiber in a piano just marketing?
- It is the same reasoning that put carbon fiber in the Boeing 787, Formula 1 cars, and elite bicycles: more strength and stiffness at lower weight. Infusing carbon fiber into Kawai’s ABS-Styran increased part strength by 90%, letting the action move faster with less effort. Kawai has refined composite action design for more than 50 years — longer than anyone in the industry.
