The surcoat is said to have been worn by Oda Nobunaga. He was known for his preference for unconventional attire and behavior, which earned him the nickname “Ootsuke” (a quirky, unconventional person) (according to the “Shinchō Kōki”). This battle surcoat offers a glimpse into that aspect of his personality.

The garment mixes different materials, with black mountain bird feathers embroidered on the upper part and pleated silk woven with a Chinese floral pattern on the lower part. The swallowtail butterfly pattern on the center of the back is the Taira clan’s representative family crest (in which Oda Nobunaga is descendant upon), and is intricately crafted by embroidering and cutting each individual white feather.

A Surcoat) made from rare materials was no longer merely a practical item for protection against rain, wind, and cold. It appears to have been a fashionable item used to flaunt one’s wealth and charisma, and to showcase individuality and aesthetic sense.
