Need a good close up of the sticker on it and make sure it is upright so we can read it !! I would doubt its Japanese Imari !! But the same style was made in both China and England !! Can not tell more without reading the label !! It appears very modern !!
Where did you buy this piece ?? Keep in mind that Imari is not a particular brand ,,it was just the port from which it was exported !! There were many factories that produced porcelain in that region !! Imari is simply a style of decoration !! Like Capo di monte is !!
