Kōyō Kawanishi (川西 浩陽, Kawanishi Kōyō, born January 18, 1959) is a Japanese dentist, amateur astronomer and discoverer of 13 minor planets.[1][2]

He lives in the city of Akō in the Hyōgo Prefecture, Japan, where his private Minami-Oda Observatory (374) is located.[3] At the observatory, he observes comets and minor planets using his home-made 0.20-m reflector telescope together with his wife Kumi and daughter Saki. Familiar with electronics and mechanics, he has also developed his own CCD instrumentation.[2]

The asteroid 5591 Koyo, discovered by Japanese astronomer Takeshi Urata, was named in his honour.[2]
