This is a bottle from around the 1960s that comes with a music box, designed for the American market. Using a double-walled construction, the inner side includes a Japanese doll. Turning the screw on the bottom will play the traditional Sado Okesa tune and the cute kimono-clad doll will rotate in time to the music, dancing elegantly. This tokkuri (flask) comes with a doll and a music box, so it is almost like watching a revue inside the sake. After the sake is added to the bottle, the music box is attached to the bottom of the bottle. This is very fiddly work, and we do wonder how American consumers saw this innovative product.
At the time, this was sold in major cities in the United States through a Japan-based trading company and a Chicago sales agent. It would have been loaded on the ship around September and arrived in stores around November, so many customers would have bought it as a Christmas gift.
