Edo Sekku Ningyo are dolls made in 12 Tokyo wards and four Saitama cities, including ichimatsu (play dolls), gosho (palace dolls), and armored dolls. Originating in the late Edo Period, these dolls were initially displayed outdoors but later became smaller for indoor display. Crafted from natural materials like leather, silk, and wood, they are known for their realism and fine detail. Influenced by Kyoto's doll artisans, the Jirozaemon-bina style (characterized by round faces and minimal makeup, simplified court robes, and stiff bodies) became popular, making Edo Sekku Ningyo a cherished cultural tradition.
