Taiki Shuttle was originally slated to enter Fujisawa Stable's Miura training center in the fall of his juvenile year, but the schedule was delayed due to leg injury and hoof suppuration. He entered Fujisawa stable on February 5, 1997. Even after he entered the area, he was troubled by moyamoya disease in his legs, and the condition deteriorated with training, so his debut was again delayed. His connections' patience paid off as Taiki Shuttle broke his maiden at first asking in a maiden race at Tokyo Racecourse on April 19, 1997 going 1600 meters on dirt, and won his next two races, including the Shobu Stakes on turf. He tasted defeat in his fourth start when running second to Tenzan Storm in the Bodaiju Stakes at Hanshin Racecourse. Taiki Shuttle won his first graded stakes next in the Group 3 Unicorn Stakes. He would not be defeated again until his final race. He then won the Group 2 Swan Stakes as a prep race for the Mile Championship, a prestigious mile race in Japan, which he won. He then won the Sprinters Stakes to close out the year. He was named Best Sprinter or Miler of 1997 by the Japanese Racing Association.
1998
Taiki Shuttle opened 1998 with a win in the Group 3 Keio Hai Spring Cup in May. The next month he won the Group 1 Yasuda Kinen. After the Yasuda Kinen, Taiki Shuttle shipped out to France to run in the Group 1 Prix Jacques Le Marois. He won the race and then went on to win his second Mile Championship. In his final career race, he tried to repeat in the Sprinters Stakes, finishing third behind Meiner Love. Taiki Shuttle was named Horse of the Year, Best Sprinter or Miler, and Best Older Male of 1998 by the Japanese Racing Association.
Taiki Shuttle stood his stallion career at stud at Arrow Stud in Shinhidaka, Japan. He periodically shuttled to East Stud in Hokkaido. Taiki Shuttle was pensioned from breeding and moved to Kimura Farm in 2018, a retirement facility for racehorses connected with East Stud and Versailles Farm. He was moved to the farm along with Meisho Doto, another pensioned stallion. The two underwent successful castration in January of 2019. On September 15, 2019, the manes of Taiki Shuttle and Rose Kingdom, a fellow JRA Champion, were mysteriously cut by an unknown person. It appeared that a sharp tool had been used to cut the hair, but the horses were otherwise unharmed. The farm filed a report with the Hokkaido Police and ceased visitation to the farm for security and investigative purposes. Taiki Shuttle's notable progeny include:
