- He was put up for sale when he was zero years old, but no takers were found.
He was also offered at the sale as a yearling and JRA sold him for 8 million yen.
He was then trained by JRA and shown at the JRA Breeze Up Sale.
(The purpose of these moves by JRA is to conduct research and studies for the development of strong racehorses.
The JRA’s practice of purchasing racehorses that cannot be bought, training them, and selling them at relatively low prices is also said to have the purpose of protecting small breeders and less affluent horse owners.)
He was so highly rated that he was sold for 26 million yen, the highest price in the history of the JRA Breeze Up Sale at the time.

- In the Niigata Nisai Stakes, he was the 1st favorite.
He was in last place, but took full advantage of the long and wide homestretch of Niigata Racecourse to overtake the horses in front of him.
He won his first grade race by 1+1/2 lengths.
It was also the first grade race win for the breeder, Yukifumi Tsutsui (Tsutsui Farm).
After this race, an happening occurred.
Nishiyama Farm received congratulatory phone calls and bouquets of flowers.
The Nishiyama family of Nishiyama Farm produced and bred racehorses named “Seiun,” which led to the mistaken belief that Seiun Wonder was produced by Nishiyama Farm.
The name of Seiun Wonder was a simple combination of his sire’s and dam’s names.
(His dam, Seiun Kunochi, had been a Nishiyama Farm horse, but was sold to Tsutsui Farm in 2003.)
(Almost similar happenings have occurred in the past with Shadai Kagura.) - In the Asahi Hai Futurity Stakes, he was the 2nd favorite.
He passed the other horses on the inside in the homestretch to take the lead.
He won by a neck.
He was the first horse from the JRA Breeze Up Sale and the first JRA-trained horse to win a G1 race.
It was his owner’s first G1-level race win in his 43 years of horse ownership.
It was of course the first G1 win for the breeder.
(It is said that congratulations were also mistakenly given to Nishiyama Farm at this time.) - In 2009, he did not win, but he had a decent showing, finishing third in the Satsuki Sho, third in the Kobe Shimbun Hai, and third in the Kikuka Sho.
However, he missed out on prize money that would have been added if he had finished second or higher. - In 2010, his connections planned to run in the Yomiuri Millers Cup to the Yasuda Kinen.
He finished fourth in the Milers Cup and registered to run in the Yasuda Kinen, but was unable to run due to the lack of prize money he had earned. - He won the Epsom Cup, which he ran instead of the Yasuda Kinen.
He then ran in the Takarazuka Kinen, but finished in 16th place, the lowest finish. - He then underwent a lengthy recuperation due to an injury.
In 2012, he was on track to return to racing, but due to a recurrence of his injury, he was unable to return and eventually retired from racing
