Antique Japanese Mixed Metal Covered Box

This appears to be an antique Japanese mixed metal covered box, likely dating from the Meiji period (1868-1912) due to its aesthetic and characteristic use of mixed metals. The box is predominantly crafted from a yellow brass or bronze alloy, forming a rectangular shape with gently rounded corners and convex sides. The lid fits snugly over the base, suggesting a well-made construction intended to protect its contents. The primary decorative elements are applied or embedded mixed metal motifs, primarily in a reddish-brown copper alloy, depicting what appear to be floral or botanical designs. These designs are executed in a repoussé or chiseled technique, creating a low relief that stands out against the brass background. One prominent feature is a square cartouche-like marking on the lid, containing what looks like a stylized kanji or character, possibly a maker's mark or artist's signature; however, details are indistinct due to the image resolution and condition. There are also several small, circular, silver-colored studs or rivets seemingly embedded into the brass, flanking some of the decorative elements, which could be part of the design or possibly later repairs/additions. The overall condition shows significant signs of age and wear. The brass has developed a dark, uneven patination and appears somewhat dull, with various scuffs, scratches, and possibly some surface corrosion. The relief decorations show wear and some loss of detail, indicative of handling over many years. There are no obvious major dents or breakages, but finer details are hard to ascertain. The craftsmanship, particularly the detailed mixed metal work and the seemingly tight fit of the lid, suggests a quality piece for its era, likely intended for a specific purpose such as holding incense, trinkets, or personal accessories.
