Vintage Japanese Military Police (Kenpeitai) Uniform Button

This is a circular, convex uniform button, likely from the Imperial Japanese era, specifically associated with the Kenpeitai (Military Police). The item is crafted from a copper-based alloy, commonly brass or bronze, and displays a prominent dark, aged patina with hints of golden metallic highlights peeking through on the raised surfaces. The design features a central oval shield bearing the stylized 'Ken' (law/police) kanji, topped by a sunburst or chrysanthemum motif. Flanking the shield are traditional military trophies, including crossed rifles or flags and a laurel wreath tied at the base with a bow. This specific iconography was characteristic of the Meiji to Showa eras (late 19th century to mid-20th century). The construction appears to be a two-piece pressed metal design, typical for high-quality military tailoring during that period. Condition-wise, the button shows authentic signs of wear, including minor surface abrasions and deep oxidation in the recessed areas, which actually enhances the legibility of the intricate relief. There are no visible maker's marks on the front; such marks are traditionally located on the reverse side (not pictured). The overall craftsmanship reflects the high standards of official government-issued regalia from early 20th-century Japan.
