Hi Jenna, This is likely Japanese. Shapes like this were almost non-existent in Chinese antique porcelain, but it would be normal for Japanese ceramics.

green glazed pottery jar by: peter
This is no cup. Cups never have this type of top rim. Depending on its size it is likely a lidded jar or censer. Was the black lid there when you bought it? Looks like a typical black lacquered lid made in Japan. They frequently use these for items with no/missing lid. The shape itself also does not look Chinese, but could be Japanese, if it is a traditional/antique item.
