I believe this is mid to late 20th century, the shape and the way the water is painted looks modern to me.

Looks as if it had some age, but it is likely Japanese. This shape is non-existent, both in traditional as modern Chinese porcelain. It s beaker-shape and the flat areas around the circumference are typical for Japanese tea cups used when serving food.
Motif is Chinese but bottom also looks more Japanese.
