11151 Oodaigahara           Discovered 1997 Dec. 24 by T. Kobayashi at Oizumi.
Oodaigahara is located on the southern end of the mountain-chain boundary between Nara and Mie prefectures. It affords beautiful views and is one of the 100 celebrated mountains in Japan. Oodaigahara is in the National Park of Yoshino-Kumano and was registered as a UNESCO world heritage site in 2004.
