Fukushima Buzan is considered the foremost master of Aka-e (red-painted porcelain), so much so that he is synonymous with the art form, and it is said he painted everything. This piece is believed to be by the Living National Treasure, Fukushima Buzan. The difference in style is likely due to this piece being made in his early, unknown period. The twelve colors of eboshi (formal headwear) were used to represent rank and status. From left to right, representing the highest to lowest ranks, they are: purple (very high rank), blue, red, yellow, white, and black. Using a color reserved for a higher rank than one's own was forbidden, and this was known as kinjiki (forbidden colors).
