The Kariyushi Club is a group of grown-ups who work together to make their community better. They do things like help clean up parks and streets, give money to people who need it, and teach others how to be good helpers too. The word “kariyushi” means “happy” in the language that people speak in a place called Okinawa, which is a special island in Japan. The club is named after this word because the people who join the Kariyushi Club want to make themselves and others happy by being helpful and kind.
