Kaoru Ikeya (池谷 薫 Ikeya Kaoru?, born 1943)[citation needed] is a Japanese amateur astronomer[1] who discovered a number of comets.

As a young adult, Ikeya lived near Lake Hamana and worked for a piano factory. During his employment there, he made his first discovery in 1963 with an optical telescope he built himself within his low budget.[2] Two years later, he discovered the bright comet C/1965 S1 (Ikeya-Seki). Ikeya discovered the periodic comet 153P/Ikeya-Zhang on February 1, 2002 in Mori, Hokkaidō.[3][4] The asteroid 4037 Ikeya is also named after Ikeya. On November 13, 2010, Ikeya discovered the P/2010 V1 (Ikeya-Murakami) comet using an optical telescope, rare in an era with access to digital imaging technology.[1]
