Last weekend I had a good conversation about Japanese antiques and we discussed the Emperial symbol the "Kikumon". The person thought the Kikumon arose by the Emperor when starting the Meji restoration. However I have a pair of Abumi on which several Chrysanthemum has been inlayed (many types of Chrysanthemum kamon were used). Those abumi are probably from the Edo period.
My question is, is the Kikumon designed or even redesigned for the Mejirestoration or has it been used by the Emperor for centuries?
