Yuji Hyakutake (百武 裕司 Hyakutake Yūji, July 7, 1950, Shimabara, Nagasaki – April 10, 2002, Kagoshima) was a Japanese amateur astronomer who discovered Comet C/1996 B2, also known as Comet Hyakutake on January 31, 1996 while using 25×150 binoculars.
Hyakutake graduated from the Kyushu Sangyo University as a photography major and started working at a newspaper in Fukuoka. He first became interested in astronomy after seeing Comet Ikeya–Seki in 1965. He began searching for comets in 1989. In 1993, he moved to Hayato for because “the skies were much clearer there” and so he could better continue his search for comets. His first discovery was Comet C/1995 Y1, on December 26, 1995.
