After the war, Shigeru was adopted by the Kawai family, where he initially worked as a factory laborer, deeply committed to his job. Three years later, he began learning piano design from his adoptive father, Koichi Kawai, a pioneering piano engineer known for his contributions to the industry. Koichi emphasized the importance of craftsmanship and quality in piano making.
Following Koichi’s sudden passing, Shigeru took over the company and dedicated the next 35 years to elevating Kawai into a leader in the piano industry, renowned for its quality. Shigeru often expressed his passion for his work, stating, “Creating pianos is the greatest job I have ever had!”
Made in Japan, the SK-6 is an instrument of profound beauty and character that will captivate both the eyes and ears in any performance setting.



Spruce is the perfect material for piano keys because it is light but strong. It maintains its shape and responds well, allowing pianists to express subtle nuances in their playing. The keys are longer for easier playing and a more uniform feel, and they have a taller profile for added strength and power.

NShiko Seion hammers, meaning “ultimate voicing” in Japanese, are crafted exclusively by Kawai’s Master Piano Artisans who supervise the entire process. Each hammer is carefully hand-pressed and voiced without heat or artificial hardeners, ensuring exceptional dynamic response and expression.

KAWAI’s skilled craftsmen carefully and precisely hand-wind copper wire around the bass strings to ensure top quality.

Shigeru Kawai Concert Agraffes, made from solid brass for strength and precision, are identical to those on our famous EX Concert Grand Piano. They produce a clear, powerful tone

The custom-tapered soundboard in a Shigeru piano is made exclusively from the finest spruce, aged by the traditional kigarashi process that uses only the forces of time and nature to allow the wood to attain a state of natural balance.
It is this lengthy and painstaking process that gives Shigeru pianos their uniquely rich tonal quality.

The Stretcher Over-Lap Integrated Design (SOLID) provides a strong foundation for string tension. In this construction, the pinblock is carefully fitted to the plate, and the pinblock is combined with the overlapping stretcher bar to form a single, sturdy structure that’s firmly anchored to the rim.
This design ensures excellent strength and stability, leading to reliable tuning and a rich sound.

Spruce is known for its outstanding ability to conduct and conserve sound energy. However, it is generally considered too precious for use as a structural material. For the Shigeru pianos, all of the underside beams are made entirely of the highest quality spruce.

Meticulous attention to the needs of professional performers is evident in every feature of the Shigeru piano. One example, originally developed for our Shigeru Kawai EX Concert Piano, is the unique dual-pivot damper design that allows smoother half-pedal control for delicate tonal expression.
