11155 Kinpu           Discovered 1997 Dec. 31 by T. Kobayashi at Oizumi.
Kinpu, one of the 100 most celebrated mountains of Japan, is located in the Oku-Chichibu area. From its 2595-m peak the view is beautiful. Kinpu presents a gentle mountainous profile, and a characteristic projection made by a large rock is known as Gojo-iwa.
