Unique to the Kyushu region, Kiji guruma are produced in Fukuoka, Kumamoto, and Oita prefectures. The toys are carved out of wood to resemble a pheasant, with wheels and a string attached, and children play with them by pulling them outdoors. There are several theories as to why pheasant cars are only found in the Kyushu region. One is that they were imported from cultures outside of Japan. Another is that pheasants were considered auspicious birds in myths. A third theory is that they originated from the secluded life and faith of remnants of Heike clan members living deep in the mountains.
