The uniquely practical 122 cm K-400 features a grand-style music rack that places music at eye level and provides a solid surface for sheet music and oversized music books. The dual-hinged fallboard adds to its distinctive appeal.

Why K-400?

The mighty Millennium III action features components made of ABS-Carbon, an incredibly lightweight, rigid composite material that provides a stronger, faster action, with more power, better control, and greater stability than conventional all-wood actions.

K-400 features an elegant dual-hinged fallboard and sleek grand piano-style music rack.  Dimensionally the same as the K300J, the K400 offers a unique cabinetry and timeless nickel fittings for a more streamlined and striking exterior.

Mahogany hammer mouldings are lightweight and extremely responsive. Found on only the finest pianos, mahogany is used for the hammer mouldings on the entire line of K Series Professional Upright Pianos,

To eliminate warping, a heavy-guage steel angle iron is added to the keyslip. Keys move more freely with virtually no possibility of rubbing or sticking against the keyslip.

We’ve been making pianos in Japan since 1927, and we’re still making them there today. With premium materials sourced from around the world – including Australian and New Zealand wools – K-400 benefits from more than 90 years of experience in-house.
