Okame Mask - Gassan

Tokujiro Iwaki became a disciple of Choshiro Shibue around 1891, trained for 13 years, and became independent in 1915, opening the current Iwaki Doll store.
The Shibue Doll, which was thought to be extinct, has its techniques passed down to Iwaki Doll store under the name Yamagata Hariko.
The main dolls of Yamagata Hariko include ball-riding monkeys, nemuri tigers, daruma, and masks (Okame and Hyottoko).
