24889 Tamurahosinomura           Discovered 1996 Dec. 11 by T. Seki at Geisei.
"Tamurahosinomura" ("the star village") opened in 1992 near the Abukumado limestone cave in Fukushima prefecture. The 0.65-m reflector at Hoshinomura Observatory was rendered unrepairable by the Great Eastern Japan Earthquake in March 2011, but was reborn as the "KIZUNA Telescope" in July 2012.
