14795 Syoyou           Discovered 1977 Mar. 12 by H. Kosai and K. Hurukawa at the Kiso Station of the Tokyo Astronomical Observatory.
Tubouchi Syoyou (1859-1935) accomplished the first complete translation of Shakespeare's dramas into Japanese. These works inspired the first discoverer to write his book Shakespearean Star Stories.
