How this kanji evolved

Explore each form from the oldest known stage to today.

The character 赤 (red) evolved from ancient pictographs depicting a human figure with fire below, originally meaning 'bright red' or 'bare/naked.' In oracle bone script, it showed flames beneath a person, representing the color of fire. During the bronze script period, the character simplified to combine 大 (big/person) with 火 (fire), though the fire component later transformed into the modern form. The character's meaning expanded to include 'pure,' 'sincere,' and 'bare' (as in 赤裸裸 - completely naked), reflecting how red was seen as a fundamental, unmixed color in ancient Chinese philosophy. Arrived in Japan: The character 赤 arrived in Japan during the 5th-6th centuries CE, primarily through the introduction of Chinese writing systems via Korean peninsula. It appears in early Japanese texts like the Kojiki (712 CE) and Manyoshu (8th century), where it was used both for the color red and in compound words. The character was fully integrated into the Japanese writing system by the Heian period (794-1185).
