35370 Daisakyu           Discovered 1997 Oct. 29 at the Saji Observatory.
Tottori-Dai-Sakyu (Tottori Sand Dunes) is Japan's greatest sand dune, fully 16 km in east-west length, 2 km in width and 92 meters high. Saji Village, where Saji Observatory is located, merged with Tottori City, home of Tottori-Dai-Sakyu, in 2004. The naming of this minor planet commemorates the merger.
