Squared Katakana Sa (Apple)

On Apple devices, the Japanese service charge button emoji is a vibrant crimson circle, instantly recognizable for its bold kanji character. Apple’s design imbues this button with a smooth, glossy texture and a subtle gradient that suggests a tactile, pushable interface, making it feel real and functional. The intensity of its red hue speaks to urgency or importance, commonly used in digital communications to signify a service fee, a special offer, or a point of interest within a Japanese context on Apple devices.
