Karakuri dolls are the first automata in Japan. <br />Their movements are caused by the power of springs, mercury and sand without <br />ever uning single metallic screw or nail. They did and do attract people. <br />Japan boasts to the world the ultimate reproduction of karakuri dolls, <br />which has been achieved by Harumitsu Han-ya, the master craftman. <br />http://karakuriya.com/english/index.htm
