 > Could you please tell me where your acoustic pianos and Disklavier

 All of our grand pianos and uprights taller than 45" are manufactured
 in Hamamatsu, Japan.  Vertical pianos 45" or less are manufactured in
 Thomaston, Georgia.  This is true of both acoustic and our Disklavier
 pianos.

 > Are the components also manufactured in Japan and the US?

 All of the pianos made in Japan are made with Japanese parts.  Pianos
 made in Thomaston, Georgia, are a combination of Japanese and American
 parts.  Japanese parts used: all Disklavier electronic components,
 hammers, action, tuning pins, pedal trapwork, plates and pressure bars.
 All other components are American made.

 I hope this information helps.
