This bronze mirror is attributed to the Edo period (AD 1603–1867).
The object is rectangular, with its height exceeding its width, and features a plain, unadorned mirror surface. The reverse side is equipped with two bosses aligned along the central axis—one positioned towards the upper section and the other towards the lower—both of which are slightly raised and hemispherical, with lateral perforations to facilitate suspension cords. The central field is occupied by the primary motif, which depicts the foliage and stems of the sacred bamboo (Nandina domestica), interspersed with clustered berries. Inscribed in the lower-left corner is ‘Tsuda Satsuma-no-kami’, the moniker of a renowned master mirror-smith. The background surrounding the decorative patterns and the inscription has been stippled using the ishime-guchi (stone-texture punching) technique to produce a rough, granular surface texture reminiscent of natural stone.
The genealogy of the Japanese wakyo (indigenous Japanese mirror) can be traced back to the Yayoi period (c. 300 BC–AD 250), during which Han-style imported mirrors from the Chinese mainland were deposited in elite burials as symbols of authority. This was followed by the development of locally replicated mirrors (boseikyo) and distinct indigenous motifs during the Kofun period (c. AD 250–538), whilst mainland influence persisted through the continuous reception of Tang-style mirrors during the Asuka (AD 538–710) and Nara (AD 710–794) periods. It was not until the Heian period (AD 794–1185) that the wakyo emancipated itself from Chinese stylistic hegemony to establish a distinctive, uniquely Japanese aesthetic idiom (wakyo-yashiki). This idiom shifted the decorative focus towards auspicious motifs symbolizing longevity and prosperity—such as cranes, tortoises, pines, bamboos, chrysanthemums, and natural landscapes—often rendered in pictorial, painting-like compositions. This ornamental tradition endured through the Muromachi period (AD 1336–1573) and into the Edo period. During the Edo period, wakyo underwent a profound transformation characterized by heightened utilitarianism and widespread popularization, which manifested clearly in its typology and chronological development. Typologically, the primary manufacturing output shifted dramatically from traditional circular mirrors to e-kagami (handled mirrors) and rectangular hako-kagami (pocket or pocket-sized mirrors) suitable for carrying within the robes. The reverses of these mirrors were frequently cast with the signatures of celebrated mirror-smiths, and material analyses suggest the ubiquitous deployment of a tinning process, wherein a silver-white metallic thin film was applied onto a brass or shakudo (copper-gold alloy) substrate. Chronologically, managed mirrors produced prior to the mid-Edo period are typified by relatively slender and elongated handles; however, by the late Edo period, the maturation of fumikaeshi (re-casting or surmoulage) technology facilitated industrial-scale mass production. Consequently, the consumption of bronze mirrors democratized, expanding from the aristocratic samurai class to the general populace. Handled mirrors of this late phase were commonly integrated into bridal dowries and popularly cast with oversized, bold calligraphic inscriptions conveying propitious blessings. This formed a popular bronze mirror culture unique to the commoners of the Edo period, which persisted until its ultimate obsolescence following the ubiquity of glass mirrors during the Meiji era (AD 1868–1912).
