The history of Tanaka Precious Metals began in 1885 (Meiji 18) when Tanaka Umegichi founded the currency exchange shop 'Tanaka Shoten' in Nihonbashi.
In 1892 (Meiji 25), founder Yamazaki Kamekichi, operating as a precious metal jewelry wholesaler in Tokyo, was the first in Japan to draft regulations specifying gold purity such as K18 and K24, greatly influencing the precious metals industry.
In the 1920s, even combs and hairpins made from high-purity gold were engraved with purity marks, exemplifying the founder's commitment to safeguarding the credibility and quality of precious metals.
In 1923, a comprehensive agency agreement for platinum imports in the East was signed with the Soviet Union, then the main platinum-producing country.
In 1930, it became a subsidiary of Tanaka Shoten (now Tanaka Precious Metals).
In 2003, the London Bullion Market Association (LBMA) selected it as an 'Authorized Testing Company' to assess the melting technology and analytical capabilities of gold and silver refiners.
In 2009, it received certification as an 'Authorized Testing Company' from the London Platinum and Palladium Market (LPPM).
