2000: two-year-old season Kurofune's first two runs were at
Kyoto Racecourse in the autumn of 2000. After finishing third in a
maiden race over 1600 metres on 14 October, he then set a track record when he won a similar event over 2000 metres two weeks later. He then appeared at
Hanshin Racecourse on 3 December and set another track record when he won the 2000 metres Erica Sho. Later that month at the same venue he was stepped up in class for the
Grade 3 Radio Tampa Hai Sansai Stakes and came home third of the twelve runners behind
Agnes Tachyon and
Jungle Pocket.
2001: three-year-old season On 24 March at Hanshin, Kurofune recorded his first major win when he was a wide-margin winner of the Grade 3 Mainichi Hai over 2000 metres. Kurofune was moved up in distance for the
Tokyo Yushun over 2400 metres three weeks later and came home fifth of the eighteen runners behind Jungle Pocket, Dantsu Flame, Dancing Color and Born King. Following the summer break Kurofune returned in September for the
Kobe Shimbun Hai (a trial race for the
Kikuka Sho) over 2000 metres at Hanshin and ran third behind Air Eminem and Sunrise Pegasus. Having raced on turf in all of his previous races, Kurofune was switched to
the dirt for the Grade 3 Musashino Stakes over 1600 metres at Tokyo on 27 October, winning from Eagle Cafe (2000 NHK Mile Cup) in a new track record of 1:33.3. Lido Palace's rider
Jerry Bailey commented "[Kurofune] was going so easy. He passed me without any effort, and my horse had no fight in him when the gray horse came to him". In December it was announced that Kurofune had sustained a serious injury to the tendons in his right foreleg and that he would be unable to race again. In January 2002 Kurofune was voted
Best Dirt Horse in the
JRA Awards for 2001. ==Racing form==
