46595 Kita-Kyushu           Discovered 1992 Dec. 29 by T. Seki at Geisei.
Kita-Kyushu is a city in Fukuoka prefecture. Since the first government-managed steelworks was installed there in 1901, the city has contributed to the modernization of Japanese industries. Kita-Kyushu overcame pollution and has been revitalized as a "green" city.
