These three coins were minted in Japan and are modeled after ancient Chinese designs. They are easily distinguished by their square hole in the center which allowed the owner to wear the coins on a string around the neck, making them harder to lose. In modern Japan, coins are still made with holes in the middle because it uses less metal and makes them easier to identify for people with visual impairments.
