Japanese numismatic charm
Japanese numismatic charms (Japanese: 絵銭 or 画銭), also known as Japanese amulets, Japanese talismans, or simply Japanese charms, are a family of cash coin-like and other numismatic-inspired types of charms that like the Korean and Vietnamese variants are derived from Chinese numismatic charms (also referred to as Yansheng coins or huāqián), but have evolved around the customs of the Japanese culture. Although most of these charms resemble Japanese cash coins and the amulet coins of China, they contain their own categories unique to Japan.
