The U1J was designed based on Yamaha's acclaimed U series upright acoustic piano line. Complementing the U series'excellent tonal characteristics with exterior refinements, it features a well-polished finish that maintains the beauty of the instrument over a lifetime.

Features
Advanced Scale Design
Refinements in all elements of sound production have given today's U series a richer , more resonant voice with evenly balanced timbre across the entire keyboard.

Soundboard and Frame
Special lib configurations add strength to the soundboard, while back post and other advances further enhance rigidity, resonance and structural stability.

Redesigned Hammers
U Series hammers use materials specifically selected for each model to provide optimum tone production, response and long-term durability.

Soft-Close Fallboard
A damping mechanism, formerly used only in grand pianos, prevents the fallboard from dropping abruptly onto the keyboard, guarding against accidental injury or damage.
