Rhein Kraft was a dark bay mare with an irregular white blaze bred in Japan by Northern Farm. During her racing career she was trained by Tsutomo Setoguchi and raced in the pink and green colours of Shigemasa Osawa. She was ridden in most of her races by Yuichi Fukunaga. She was sired by End Sweep an American horse who won six races in the United States including the Grade IIIJersey Shore Breeders' Cup Stakes in 1994 and was later imported to Japan to become a breeding stallion. His other progeny have included Admire Moon, Sweep Tosho and Swept Overboard. Rhein Kraft's dam Must Be Loved showed no racing abiility, failing to win or place in three starts, but did better as a broodmare as she also produced Admire Royal and Florentino. Her dam Dyna Shoot was a successful racemare who won the Keio Hai Nisai Stakes, Tanabata Sho and Niigata Nisai Stakes. She was a female-line descendant of the Californian broodmare Fancimine who was imported to Japan in 1971.
Racing career
2004: two-year-old season
Rhein Kraft made a successful track debut when she won a maiden race over 1400 metres at Kyoto Racecourse on 16 October. Three weeks later the filly was stepped up in class for the Grade 3 Fantasy Stakes over the same course and distance and won from Monroe Blond and eleven others. On 5 December at Hanshin Racecourse Rhein Kraft was moved up to the highest level to contest the Grade 1 Hanshin Juvenile Fillies over 1600 metres and finished a close third, beaten a head and a nose by Shonan Peintre and Ambroise. In the official Japanese ratings for 2004, Rhein Kraft was rated the second-best two-year-old filly, level with Ambroise and a pound behind Shonan Peintre.
2005: three-year-old season
On her first appearance as a three-year-old, Rhein Kraft won the Grade 2 Fillies Revue, a major trial race for the Oka Sho, over 1400 metres at Hanshin on 19 February, beating Daring Heart and Air Messiah in a close finish. In the Oka Sho at the same track on 10 April Rhein Kraft started second favourite behind Cesario, while the other sixteen runners included Shonan Peintre, Ambroise, Daring Heart, Air Messiah, Monroe Blond, Lailaps, Felicia and Eishin Tender. Rhein Kraft was in contention from the start, went to the front in the straight, and held off a strong late challenge from Cesario to win by a head. Four weeks after her win in the Oka Sho, Rhein Kraft was matched against male opponents in the NHK Mile Cup at Tokyo Racecourse. Daring Heart was again in opposition, while the sixteen colts in the race included Big Planet, Meiner Hearty, Peer Gynt and Deep Summer. Rhein Kraft was always going well and won "effortlessly" by one and three quarter lengths from Daring Heart. After a four month break Rhein Kraft returned in September when she finished second to Air Messiah in the Rose Stakes over 2000 metres at Hanshin. At Kyoto on 16 October she again ran second to Air Messiah when she was beaten a neck into second place in the Grade 1 Shuka Sho. On 20 November the filly faced older horses for the first time in the Mile Championship at Kyoto, a race in which she started at odds of 5.9/1 and finished third behind the four-year-old colts Hat Trick and Daiwa Major. She ended the season by finishing fourth behind the five-year-old mare Admire Groove in the Hanshin Himba Stakes in December. In the official Japanese ratings for 2005, Rhein Kraft was rated the second-best three-year-old filly, level with Air Messiah and eight pounds behind Cesario.
2006: four-year-old season
For her first appearance of 2006 Rhein Kraft was dropped back to sprint distances for the Takamatsunomiya Kinen over 1200 metres at Chukyo Racecourse on 26 March and finished second of the eighteen runners, beaten a neck by the six-year-old Orewa Matteruze. In the Hanshin Himba Stakes over 1400 metres on 18 April the filly recorded her first win in eleven months as she came home two and a half lengths in front of her old rival Air Messiah. In the Victoria Mile at Tokyo on 14 May Rhein Kraft came home ninth of the eighteen runners, beaten five and a quarter lengths behind the winner Dance In The Mood. On 18 August Rhein Kraft died of acute heart failure.
