including Shigeru Kawai
Pianos made by: Kawai Musical Instrument Mfg. Co., Ltd.; Hamamatsu, Japan, and Karawan, Indonesia
Kawai was founded in 1927 by Koichi Kawai, an inventor and former Yamaha employee who was the first person in Japan to design and build a piano action. While Kawai is second in size to Yamaha among Japanese piano manufacturers, it has a well-deserved reputation all its own for quality and innovation. Nearly all Kawai grands and taller uprights are made in Japan; most consoles and studios are made in Indonesia. The company closed its North Carolina factory in 2005.
One of Kawai's most important innovations is the use of ABS Styran plastic in the manufacture of action parts. Nearly 40 years of use and scientific testing have shown this material to be superior to wood for this purpose. ABS does not swell and shrink with changes in humidity, so actions made with it are likely to maintain proper regulation better than wood actions. The parts are stronger and without glue joints, so breakage is rare. These parts are present in every Kawai piano. In the current Millennium III action found in some models, the ABS is reinforced with carbon fiber so it can be stronger with less mass. Having less mass to move (that is, less inertia), the action can be more responsive to the player's intentions, including faster repetition. Certain contact surfaces on the action parts are also micro-engineered for ideal shape and texture, resulting in a more consistent touch. Although it took a number of years to overcome the idea that plastic parts must be inferior, there is essentially no dispute anymore among piano technicians on this subject. The latest (H series) version of the Millennium III action contains resin hammer-shank stabilizers that are designed to retain power by keeping the shank from wavering under a heavy blow.
Kawai's vertical piano offerings change frequently and are sometimes confusing. At present there are three basic series of Kawai verticals. The console series begins with the 44 1/2" model 506, a basic entry-level console in an institutional-style cabinet (legs with toe blocks). Model K-15 is a 44" version of this in a continental-style cabinet (no legs), and model 508 is a 44 1/2" version in a simple furniture-style cabinet (freestanding legs). Model 607 is the same piano in a fancier furniture-style cabinet. All have the same internal workings. The action in this series is slightly smaller than a full-size action, so it will be slightly less responsive. However, it is more than sufficient for beginner or casual use.
Kawai has replaced both of its former studio models, the UST-7 and UST-8, with the 46" model UST-9, made in Indonesia. This model has the stronger back of the UST-7, rather than that of the UST-8, which was not known for its tuning stability. The UST-9 also contains the Millennium III action; an angled, leather-lined music desk to better hold music; and a stylish, reinforced bench. The 46 1/2" model 907 is essentially the UST-9 in a fancy, furniture-style cabinet. Rounding out the Kawai studios is the new Japanese-made FINO Interior Design Series of three models--the Gilda, Rosina, and Lauretta--that Kawai says are "European in style."
Kawai's K series of upright models comprises the K-2 (45"), K-3 (48"), K-5 (49"), K-6 (52"), and K-8 (52"). All have the Millennium III action; a soft-close fallboard; a wide, leather-lined music desk; a somewhat stylish cabinet; and come with an adjustable bench. The 52" models also feature agraffes, duplex scaling, Neotex synthetic ivory keytops, and various kinds of tone escape mechanisms. The K-8 has a true sostenuto pedal.
Kawai makes three series of grand pianos: RX, GE, and GM. The RX series is the most expensive and has the best features. It is designed for the best performance, whereas the GE and GM series are designed more for efficiency in manufacturing, with fewer refinements. The RX pianos have a radial beam structure, focused and connected to the plate using a cast-iron bracket at the tenor break. This system makes for a more rigid structure, which translates into better tone projection. The soundboard of the RX models is tapered for better tonal response, and the rim is thicker and stronger than in the GE and GM models. The RX pianos also use the new Millennium III action, have duplex scaling, lighter hammers (less inertia), and Neotex synthetic ivory keytops (though some of these features have been introduced into the GE and GM pianos as well). The RX grands get more precise key weighting, plus more tuning, regulating, and voicing at the factory. The cabinetry is nicer looking and of better quality than that of the GE and GM series pianos. The difference between the GE and GM pianos is primarily that the GM grands have simpler cabinetry and internal design (no agraffes, for example) than the GE. The 5' GM-10K is Kawai's first grand model made in Indonesia; the others are made in Japan.
