These are traditional Japanese costume dolls
(Nihon ningyō / 日本人形), often created as display or souvenir art pieces (commonly popular mid-to-late 20th century).
Here is a breakdown of what each figure represents:
Left (Red Kimono): Depicts a young woman or performer in a vibrant floral red kimono featuring an elaborate obi (sash) and hair ornaments (kanzashi). Figures in this pose and style are frequently modeled after traditional dancers or classical geisha/maiko representations.
Right (White & Gold Kimono with Headpiece): Depicts a Japanese bride wearing traditional wedding attire (Shiromuku / Uchikake). She is wearing a wataboshi (the large white hood/headpiece traditionally worn over the elaborate hairstyle during a Shinto wedding ceremony) and holds a small folded fan (suehiro).
Key Features:
Display Case: Glass case housings (glass-case ningyō) are designed to protect the delicate silk fabric, hair arrangements, and painted faces from dust and moisture.
Craftsmanship: The faces are typically sculpted from wood composition or plaster and coated with fine white powder finishing (gofun), styled with realistic hair, intricate embroidery, and metallic brocade fabrics.
