Meaning & readings

emperor

On’yomi コウ、オウ
Nanori おうじ、おお、み

Origin

The character combines two parts to represent an emperor. The bottom component (king) serves as a sound hint, roughly indicating how the character is pronounced. The top component (white or bright) adds meaning, suggesting the idea of brightness or clarity—qualities associated with imperial authority and divine radiance. Together, these parts created a character specifically for the highest ruler, distinguishing the emperor from ordinary kings.
