This is a Japanese-style hexagonal cast iron lantern from the mid-to-late 20th century. Crafted using the sand-casting technique, it features a hexagonal pavilion-style design: a decorated hexagonal pyramidal roof with a metal handle; the main body incorporates openwork square windows that allow light to pass through or fragrance to diffuse; and it is supported by three legs. The surface exhibits a naturally oxidized dark brown patina, exuding a Japanese aesthetic and vintage charm, making it suitable for garden decoration, display in Zen-inspired spaces, or for collection.
