Fibroin and sericin are proteins composing silk fibers. Based on the finding of amino acid sequence offibroin corresponding to wild Japanese silk moth (Antheraea yamamai) in a piece of textile excavatedfrom Makimuku archaeological site (ca. 3 century AD), the author assumed that there could exist asericulture of Japanese origin some 200-300 years before the vast influx of immigrants, prisoners of war,and refugees, who provided Japan with new sericulture using silkworm moth (Bombyx mori)domesticated in ancient China and mulberry trees needed to breed the moth. Such an innovation ofsericulture producing valuable silk textiles could possibly transform the culture, economy, and politicsof ancient Japan so greatly that its consequences must be worthy to be recorded in authoritativeliteratures including Kojiki (Account of Ancient Matters) and Nihon-Shoki (Chronicles of the History ofJapan). In this article, the author surveyed these literatures to search for myths, stories, and events,which might be associated with the use of either Japanese silk moth or domesticated silkworm moth forthe production of textiles, resulting in finding a few stories in favor of the existence of sericulture withJapanese silk moth, especially in the story of Emperor Nintoku and his wife Empress Iwano-Hime.
