“Hakoseko” From the late Edo period through the Meiji and Taisho eras, these were essential accessories for formal wear worn by women of samurai families and wealthy townspeople. Originally, they were small boxes (hakoseko) used to hold amulets and cosmetics, and were also included as part of a bride's trousseau. This "Hakoseko" has a "birakan" - a hairpin with dangling, fluttering ornaments attached to a chain. The square birakan hairpin is rare.
