In May 2026, the Agency for Cultural Affairs officially designated three old coin restoration skills — surface treatment, display stand creation, and replica casting — as Selected Conservation Techniques under Japan's Law for the Protection of Cultural Properties. The designation responds to the critical shortage of skilled craftspeople and the risk of technique extinction, and will be accompanied by certification, subsidies, and apprenticeship programs.
