Vintage large Kutani Japanese Vase, Gold with purple orchids. 10”, very good condition, one minor black spot under lip of rim (see photo)

I do not know the age of this piece but it does have makers marks or signature on bottom. This vase was donated to a museum who could not use it so it was donated to a thrift shop. This could be rated or antique, but I’m not sure. It is a very beautiful high quality piece of porcelain.
