Japanese Hairstyles: Historical Overview Part 02: Women’s Hairstyles of the Edo Period, Part 03
Hairstyle Name: Tsunokakushi (角隠し) lit. “Horn Cover”
This is a head covering worn by the bride during a Shinto wedding ceremony to “cover her horns,” which represent her jealousy, ego & selfishness. It symbolizes the bride’s resolve to become a gentle and obedient wife. It is traditionally worn over one of two Shimada-mage variations: Bunkin-Taka Shimada (文金-高-島田) or Onaga-Bunkin-Taka Shimada (尾長-文金-高-島田).
Both the aforementioned hairstyles are, essentially, a Shimada topknot with a high base for the knot. The form of this hairstyle is nearly identical to the Taka-Shimada, Hariuchichi, and Yakko-Shimada styles. It seems to have occurred in various forms since the mid-Edo period. It’s elegance and dignity of form makes it one of the favorite styles of the upper classes by the late Edo period. This is now widely used by traditional brides during the wedding ceremony.
