14843 Tanna           Discovered 1988 Nov. 12 by Y. Oshima at Gekko.
Tanna is the name of a railroad tunnel on the Tokaido main line, Japan, that runs for 7804 meters between Atami and Kannami, The tunnel celebrates its 80th anniversary in 2014, and is named after the place where the first survey mission was based. Some parts of Kurosawa's 1954 classic "Seven Samurai" were filmed nearby.
