How this kanji evolved

Explore each form from the oldest known stage to today.

The character 鬼 (guǐ) originally depicted a supernatural being with a large, monstrous head and a human-like body. In ancient Chinese belief, 鬼 represented spirits of the dead or demonic entities. The character evolved from oracle bone script depictions of a figure with an oversized, frightening head, reflecting the ancient conception of ghosts as terrifying apparitions. Over time, the character standardized into its modern form while retaining the essence of a supernatural creature. In Chinese culture, 鬼 carries both negative connotations (ghosts, demons) and appears in compounds like 鬼魂 (ghost spirit) and 鬼神 (ghosts and gods). Arrived in Japan: The character 鬼 arrived in Japan during the 5th-6th centuries CE along with the broader introduction of Chinese writing system (kanji) through Korean scribes and Buddhist texts. It was adopted into Japanese as 'oni' (おに), referring to demons, ogres, or trolls in Japanese folklore, often depicted with horns, sharp claws, and wild hair, becoming an integral part of Japanese mythological tradition.
