Just my two cents as the owner of an iki-ningyo, this looks more to me like a 1960s maaaybe 70s store mannequin. The make-up and face structure gives it away. My iki-ningyo looks more human:
EXTREMELY RARE Vintage LIFESIZE Japanese Iki Ningyo Woman Mannequin Head Beautiful
Wow is she awesome! I LOVE LOVE LOVE Her! A fine example of an extremely rare Gofun Japanese Iki Ningyo (Living Doll) Mannequin head. These are super hard to come across, very pricey, and rarely are for sale!!! The internet does not provide great resources about Iki Ningyo dolls in general, but they are typically found in museum exhibits or in higher-end private collections. Of the 2-3 heads that I have managed to find for sale online, and that share any resemblance to what this one may be, are priced in excess of $6000.00.
I have no idea as to the maker of this beauty/exactly when she was made. She is vintage though and LIFESIZE. She has a KA stamped on the bottom which would be the maker’s mark. She measures approx. 14.5 in. tall completely by 11 in. wide (at the widest part of the head). The base measures approx. 5.8 in. long by 4.25 in wide. She has a couple of chips in the gofun at the bottom right front and left front of the base. She is made of gofun and wood and has human hair, and glass eyes with eyelashes. She is in overall very good condition despite the couple of chips and a bit of dirtying/ware of the gofun in her neck area. Her hair is a little tusseled and the top knot a little shifted but nothing bad.
Amazing. Most definastely real human hair. - TSM
