The power to manufacture and issue coins belongs to the government. The Japan Mint carries out the manufacturing work. Sources: trade[XYZ] (contract issuer), Federal Reserve Board, Bank of Japan, trade[XYZ] (contract issuer), SIX (Secretariat of the ISO 4217 Maintenance Agency), Digital Agency (e-Gov Law Search), trade[XYZ].
