All with open 開.
Interesting fact
The Wadōkaichin coin was introduced in 708 AD and was the first coin to be issued by the Japanese government. It was made of copper and had a round shape with a square hole in the center, which was a unique design at the time. The coin was used for over 300 years and went through several design changes during that period. It's an important part of Japanese history and a valuable collector's item today.
