Squared CJK Unified Ideograph-7a7a (Apple)

On Apple devices, the Japanese Vacancy button emoji presents a crisp, rectangular button with a stylized, bold character representing 'Vacancy' (空き) in a deep, rich blue hue. Apple's design gives it a subtle 3D effect with a slight bevel and glossy highlight, making it appear tactile and officially sanctioned, like a sign you might see in a shop. This emoji is commonly used to indicate that something is available, open, or unoccupied, often in contexts related to real estate or services.
