To rectify confusion over coins experienced during Tokugawa period, new Meiji government promptly recast and unified coins. First, Meiji government decided to manufacture coins using machines made by foreign countries and started to build a mint in Kawasaki, Osaka, designed by Thomas James Walters, a British architectural engineer. In November, 1870, a mint of fully Western style was built in Osaka. A gala opening ceremony followed in February, 1871.
