(35370) Daisakyu = 1997 UF21
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.
A complete set of naming citations of the numbered minor planets is available in the Dictionary of Minor Planet Names, edited by Lutz Schmadel.
