The butterfly crest, as the core Taira emblem, appeared on the formal dress, armor, and ceremonial regalia of courtier-warriors; later works such as the Tale of the Heike also used the butterfly to symbolize Taira glory, reflecting the close link between crest and clan honor.
2. c. 1175–1180Battlefields of the western provinces and the capital region · Western ProvincesAs the Genpei conflict intensified, warriors displayed their crests on sashimono (battle banners) to identify comrades and enemies. The Taira crest system included not only the butterfly but also variant patterns developed by various Taira branches; the crest identification system became the visual language of warrior organization, loyalty, and battlefield command, profoundly influencing later Japanese crest culture.
