How can I tell if my Japanese pottery is antique?

To tell if your Japanese pottery is antique, look for markings, which usually appear on the bottoms of pieces. If you see the word "Nippon," your piece was likely produced between 1891 and 1921, making it an antique. Pieces marked with the words "made in occupied Japan" originated between 1945 and 1952 and are vintage, based on their age. A "made in Japan" marking may indicate a vintage or contemporary piece. If you don't see any of these markings, consult trusted online resources to get a rough idea of when your pottery was produced. Any piece that dates back 100 years or more is antique. Should you encounter difficulty with the dating process, a certified appraiser or knowledgeable antique dealer can assist you. On 1stDibs, shop a variety of Japanese pottery.
