Ayaha-gu Ikeda Shrine

Silk weaving in Japan
The Hata, one of the most famous [Korean] peninsular families to make Japan their home in the ancient period, “presented thread and silk cloth as tribute, and when the emperor donned the clothes they were soft and warm to the skin.” The name Hata appears on a tapestry made for Prince Shotoku now kept at Horyu-ji, suggesting that the Hata might have specialized in weaving techniques.
