How do you find a value of a numbered vase made in Japan?

Answer 1

Many Japanese vases have makers marks or paper labels such as kyoto -- you look first for and kunji marks decipher from China, or ect.

Then account shape, porcelain content any theme painting to specific region Japan has a registry as they take craftmanship seriously...

Just a number will tell only mass produced.... there are over 22 vase/ceramic guilds in japan today over various prefectures usually it's worth googling guilds in japan of modern producers and collectors for insight.

there are many kyotos that flooded the market 1960's - mid 1980s all used paper labels those reach $12 - $119 pending size, composition or set pairings.

There have been also war pillage pieces from World War II that may go back to the Endo period or more those range in the thousands if the artisan is determined. Just be wary China makes a lot of fake Endo or Imperial japan vases as well.

I own a few modern kyoto pieces have retained the paper labels that are 45 years honestly express they reach true antique value at 100 years most as sentimental replacements per lost or broken pieces lost current with entact labels start at $60 up so condition is essential.
