The Blue Willow pattern is one of the most recognizable and enduring designs in ceramic history, originating in England in the late 18th century. It depicts a romanticized Chinese landscape, featuring a weeping willow tree, a pagoda, a bridge, and two doves, all rendered in a distinctive blue transferware. The pattern was widely adopted and adapted by numerous potteries worldwide, becoming a staple in households for generations.

This particular plate, likely produced during the "Occupied Japan" era (1945-1952), represents a significant period of post-war manufacturing. Items from this period are often sought after by collectors due to their historical context and the unique markings. While the Willow pattern itself has been in continuous production for centuries, pieces marked "Occupied Japan" hold a specific collectible appeal, signifying a time of transition and international trade.
