YAMAKIN

What YAMAKIN does

YAMAKIN Co., Ltd. is a privately held Japanese precious metals and dental materials manufacturer founded in 1957 in Osaka and now headquartered in Kochi Prefecture following a 2022 corporate relocation. The company operates four integrated business divisions: (1) precious metals bullion trading in gold, silver, platinum, and palladium; (2) precious metal refining and recycling services, including dental scrap collection and percentage-fee-based settlement (17% standard, 25% express); (3) industrial precious metal processing into sputtering targets, vapor deposition materials, and custom forms; and (4) dental materials manufacturing, which is the core franchise. The dental materials business produces alloys, ceramics, composite resins, hard resins, dental cements, CAD/CAM blocks and discs (zirconia, hybrid resin, PEEK, polycarbonate), pulp capping materials, and dental equipment including the TRS 3D Printer XL series and LED curing lights, distributed under sub-brands such as KZR-CAD, Zeocelight, Lunawing, A-Uno, and Nu:le Coat.

YAMAKIN's technology platform is anchored by a proprietary Dental Metallurgy knowledge system combining metallurgical and dental materials sciences, supported by 10 Ph.D. holders and joint research departments with Kochi University and Kochi University of Technology. The company holds ISO 9001, ISO 13485, and ISO 14001 certifications, with CE marking enabling European distribution of selected products. In Japan's dental materials market, YAMAKIN holds documented leadership positions in 2024 including #1 share in ceramic alloy for metal-ceramic restorations (39.1%), 34.0% share in gold alloys, 25.3% in silver alloys, and #1 by volume in hybrid resin blocks for CAD/CAM crowns (22.4%).

The company employs 251–500 people and sells through five owned branch offices (Osaka, Tokyo, Nagoya, Fukuoka, Sendai) plus a dealer network to dental clinics and dental laboratories. Secondary revenue streams come from precious metals investors and industrial manufacturers. Reported revenue peaked at ¥4.8 billion in the fiscal year ended June 2021; financial performance beyond that period is not publicly disclosed. The 2016 acquisition of Panasonic Healthcare's dental materials business (including zirconia operations) was a defining strategic move that built the KZR-CAD digital dental franchise.
