梅鉢紋・うめばちもん・umebachimon | 梅鉢家紋・umebachikamon
A Japanese family crest (mon or kamon) consisting of five evenly spaced circles centered around a smaller circle that is surrounded by 10 small shapes that fill the space. It resembles a stylized plum (ume) blossom.
If the design is outlined with a circle it becomes a maru-ni-umebachi-mon (丸に梅鉢紋). A common form replaces some of the smaller shapes with swords (without and with circle, 剣梅鉢紋, 丸に剣梅鉢紋).
