Beautiful Japanese Dragon Small Teacup and Saucer

This adorable little porcelain china teacup and saucer are airbrushed with lime green color and then has raised enameled dragons applied, giving it texture, and fired on. The are small, demitasse size. The saucer is 3.75 inches across and the teacup is 1 and 1/8 inches high and 2 and 7/8 inches across the rim. Both pieces are marked Japan in red on the bottom, but I do not know the age or maker.
