A Sound Born as the Culmination of Inherited Craftsmanship

The Master Series features a body design engineered to enrich tonal depth while ensuring long-term stability. Its meticulously refined structure—comprising reinforced posts and frame construction, a soundboard that amplifies resonance with ideal balance, hand-wound strings identical to those used on Shigeru Kawai grand pianos, and finely crafted components that enhance string stability—produces a sound that is powerful yet stable, warm, and harmoniously balanced.

In addition, the Master Series is equipped with both a muffler mechanism and a sostenuto pedal, a rare combination among upright pianos. This allows the instrument to adapt to the needs of any musician and performance environment, offering greater versatility in playing styles and expanded freedom of musical expression.

A Comfortable Touch at the Fingertips “Millennium III Upright Action”

Key components of Kawai’s piano action utilize ABS resin materials. This advanced material provides a level of precision, strength, durability, and resistance to environmental changes that cannot be achieved with wood alone. At the same time, its lightweight nature enhances repetition speed, control, and responsiveness, enabling more expressive and nuanced performance.

A Piano Design That Quietly Breathes Alongside Everyday Life

With its gracefully rounded cabinet and a topboard-supporting design inspired by grand pianos, the Master Series blends naturally into living spaces while projecting a refined and distinguished presence. From the bird’s-eye maple interior accents reminiscent of Shigeru Kawai grand pianos to the casters, pedals, and even internal bolts, every detail is finished with exceptional craftsmanship.

More than a musical instrument, the Master Series becomes an integral part of its surroundings—quietly enriching daily life and elevating each moment to a higher level.
