6980 Kyusakamoto is an asteroid discovered and named by the two Japanese astronomers Kin Endate and Kazuo Watanabe in 1993. Named in memory of the Japanese singer Kyu Sakamoto†, this planet also symbolizes the famous trio of which Kyu Sakamoto was a member, with songwriter Rokusuke Ei and pianist Hachidai Nakamura: in Japanese, Roku is 6, Kyu 9 and Hachi 8. Name proposed by the discoverers following a suggestion by T. Sato, A. Fujii and Y. Katagiri.
