Refinement of Poultry Standing in Japan Based on Recent Anthropo-ornithological Perspectives.

Abstract

Poultry meat and eggs are important sources of high-quality animal protein worldwide. However, poultry in Japan has historically been regarded as a symbolic or spiritual entity more than as a food source, as its roles are deeply embedded in Japanese consciousness and society. Current evidence indicates that chickens first appeared in Japan during the Yayoi period, approximately 2,000 years ago, coinciding with a period of active human migration to the Japanese archipelago. Since then, poultry has played notable roles in Japanese art, literature, mythology, and folktales. Recent advancements in molecular clock analysis or the detection of genomic modifications, such as introgression, deletions, mutations, and viral infection from trace fossil/live samples necessitate the continual revision and refinement of existing theories about human and animal history across several academic disciplines. Therefore, the objective of the present review was to elucidate the distinct and multilayered relationship between humans and poultry in Japan, incorporating recent anthropological and ornithological perspectives.
