29337 Hakurojo           Discovered 1995 Jan. 6 by T. Seki at Geisei.
Himeji Castle, in Hyogo prefecture, is Japan's National Treasure, also known as Hakurojo or White Heron Castle, because of its beauty and likeness to a white heron. This symbol of Himeji City was registered as a World Cultural Heritage site, the first in Japan, in Dec. 1993.
