U Series

The world's most popular upright.


Precise, ultra-responsive touch, clear, full-bodied tone and a reputation for reliability have made U Series pianos the choice of professional musicians, conservatories, teachers, students and music lovers, the world over. Add to that our legendary attention to every detail of every piano, and it’s no surprise that the U Series has been the world’s most popular upright for over half a century.


  • A set of rolling racks in the piano factory with a set of wood soundboards standing vertically with ribs in place.
    The U Series soundboards and ribs are crafted from solid spruce that has been hand selected at our Kitami Mill in Hokkaido, Japan giving these pianos a richer, more resonant voice and evenly balanced timbre across the entire keyboard.
  • The view of the back of an upright piano with the posts supporting the soundboard visible.
    Years of cutting-edge research, including our proprietary wood-drying process, result in back posts that maintain their shape, strength and resonance for years to come.
  • A closeup of the Yamaha logo in the 'V' of the frame.
    Yamaha was the first company to use an advanced Vacuum Shield Mold casting technology called V-Pro to create a stronger, lighter, more durable frame. Every U Series piano features a full-perimeter frame built to our exacting specifications at our Iwata Forge in Japan.
  • Hands in leather work gloves hand wrapping a bass wire.
    Yamaha artisans in our factory in Kakegawa, Japan oversee the winding of pure copper and adjust the balance and tension of each bass string to the exacting standards and sound profile of every U Series piano.
  • A closeup view of the aluminum rail in an upright piano being constructed.
    Often copied but never equaled, the patented Yamaha aluminum action rail helps assure our piano keyboards are resistant to tiny fluctuations in humidity and temperature over time.
  • A closeup of the fallboard have closed over keys.
    Inspired by our grand pianos, our damping mechanism prevents the fallboard from dropping abruptly, guarding against accidental injury or damage.
