Hello, I am a collector but not of Japanese antiques. But someone I have purchased art from offered me this vase. He believed it to be Japanese and at lease 60 years old form the Saji Trading co label on the bottom. I can not confirm that the label originally came with the vase. The vase is 11.5 inches tall and 8.5 inches wide. It has two marks on the bottom. One is a waning moon and the other may be the signature of the artist. Or at least I hope.
It has an old Saji Trading Co label on the bottom. It came from a private estate sale in Southern California
Your vase is a modern Japanese vase say from the last 20 years. I could not decipher the marks. Quality of the vase is nice but not very high. Its basic a decorative vase from one of the many recent potters in Japan. Value of this modern work is in general not very high. The Saji Trading co. label is just the company who exported / traded the vase outside Japan to, in many cases, the western countries. Funny vase from modern potter from Japan with no particular antiques value I'm afraid.
