Japanese “free of charge” button

🈚 is a symbol derived from the Japanese word '無料' (muryō, meaning 'free of charge'), officially named the 'Japanese “free of charge” button' in Unicode. It is commonly used to indicate that a service, item, or event is available without cost. In internet culture, this emoji is sometimes used to convey the idea of 'nothing' or 'emptiness,' especially in Chinese contexts due to its resemblance to the character '无.' Emotionally, it evokes a sense of ease, generosity, or occasional humor.
