江戸鼈甲 (Edo Bekko)
Edo Bekko (江戸鼈甲) is Tokyo's traditional tortoiseshell craft, worked from the shell of the Taimai (hawksbill sea turtle) — prized for its transparent amber base and dark, irregular mottling, of which only about 10% of a shell's surface yields the finest clear material. Multiple scutes are matched for pattern continuity, softened with water and heat, then stacked and press-fused between heated iron plates without any glue — a lamination technique whose success depends entirely on the craftsman's judgment of moisture, temperature, and pressure. The craft dates to the Edo Shogunate's founding in 1603; the fusing/lamination technique that enabled complex laminated forms arrived in Edo during the Genroku era (1688-1704). Tokugawa Ieyasu, the first Edo shogun, was a regular user of Bekko spectacle frames. The Tokyo Metropolitan Government and Japan's Ministry of Economy, Trade and Industry designated Edo Bekko a traditional craft product of the Kanto region in 2015. Since Japan accepted the international CITES ban on hawksbill trade in 1994, practitioners have worked from pre-ban legacy shell stock, making this one of the few crafts whose continuation depends as much on international wildlife-trade policy as on skill transmission.
