Circa 1900? I'm not expert enough in Japanese cloisonne to determine the exact decade either size of that date, but the aventurine (goldstone) enamel (around the central phoenix, the enamel with the glittery copper bits), according to Fredric Schneider, in his book The Art of Japonese Cloisonne Enamel, was often referred to as "tea gold" and came into use approximately around 1880 and afterward.
Cool that your plate still has its label. It would be nice if another forum member literate in Japanese could translate it.
Plates like this are fairly frequent on eBay, you might browse the Sold listings for a search on "Japanese cloisonne" to see typical values, which seem to vary between $75 and $300, with exceptions at either end of the scale.
