Dear pianists,Lately I've been trying to find the date and place of manufacturing by my piano's serial number. It's a Yamaha U1 and the number is H 2410886While the store which sold me the piano claims the H means the period of time the piano was manufactured (1970-1980) and the number represents the specific year, after looking up the subject in Yamaha's website I read the the H means it is made in China.Can you please help me understand?Thank youPiano & Music Gifts & Accessories (570)Re: Yamaha U1 Serial Number04/05/17 04:55 AM 04/05/17 04:55 AMJoined: Aug 2012Posts: 558. Yamaha's use of serial number prefixes vs. Model number suffixes can be confusing. To date, U1's have not been made in China, so by process of elimination, it is as the dealer states.It would take several pictures to better explain Yamaha's use of the prefix vs.

Suffix letters in general, but the use of the H is particularly confusing as they are stenciled inside in the exact same way and location.Yamaha U1 with H model suffix.made in Japan.Yamaha T118PE with H serial prefix.made in China.Tricky. Add 1925 to the year. It's the year-designation system, used in Japan, during Emperor Showa's (Hirohito) reign. He ascended to the throne in 1926, that year marked as first year of Showa.And most probably, the last date (15) is also not 2015, but the year of the next and current emperor's era (Heisei).
If I am not mistaken, it started in 1989, so 11 should be substracted to convert into Christian's era, i.e. 2004.I might be wrong though.Re: Yamaha U1 Serial Number04/06/17 01:28 PM 04/06/17 01:28 PMJoined: Aug 2011Posts: 6,262. It's possible, even likely, that this piano has been tuned many times by tuners who didn't know about or didn't bother with the log form. Perhaps it was still in Japan as recently as 2004, and if it's not there now, it's one of those mysterious gray market pianos.Or the owner did not care much about tuning during the last 15 years, perhaps.

The tuner name is the same for all the tunings, except in 1979 (54).Re: Yamaha U1 Serial Number04/09/17 12:10 PM 04/09/17 12:10 PMJoined: Apr 2017Posts: 3.
