Meaning

Sparkling, glittering, or shining brightly. Also used metaphorically for someone radiating positive energy or living a glamorous life.

キラキラ originally describes physical sparkle — stars, jewels, light reflecting off water. In modern slang, it has expanded to describe people who seem to shine with positivity, ambition, or glamour. A キラキラ女子 is a woman who presents a polished, aspirational lifestyle on social media. The term キラキラネーム refers to unusual, hard-to-read names given to children, coined because parents want their kids to 'sparkle.'
