Sweep Tosho: The Strong-Willed Queen Who Defeated Japan’s Best

Sweep Tosho was one of the most memorable mares in Japanese racing history.

She possessed an exceptional final burst of speed and won three Grade 1 races. She defeated some of Japan’s leading male horses and became the first mare in 39 years to win the Takarazuka Kinen.

Yet her racing ability was only one part of her story.

Sweep Tosho was also famous for her extremely strong personality. She sometimes refused to enter the track, resisted going into the starting gate, and even stopped moving during training. If she did not want to do something, people could not easily change her mind.

Her jockey, Kenichi Ikezoe, could never completely control her. Instead, he learned to wait for her, accept her personality, and trust her extraordinary talent.

Together, they created one of the most unusual partnerships in Japanese racing.

Early Life and Pedigree

Sweep Tosho was a bay mare foaled on May 9, 2001. She was bred by Tosho Farm in Hokkaido and raced for Tosho Sangyo.

Her sire was End Sweep, an American racehorse who later became a successful stallion in Japan. End Sweep was known for passing speed to his offspring. His other major runners included Admire Moon, Rhein Kraft, and South Vigorous.

Her dam was Tabatha Tosho, a mare from a family developed by Tosho Farm over many years. Sweep Tosho’s damsire was Dancing Brave, one of Europe’s greatest racehorses of the 1980s and the winner of the 1986 Prix de l’Arc de Triomphe.

This pedigree combined the speed of End Sweep with the class of Dancing Brave and the long history of the Tosho female family.

Sweep Tosho had all the blood needed to become a top-class racehorse. However, no pedigree could explain the powerful will that would soon make her famous.

2003 Debut: A Glimpse of Her Great Talent

Sweep Tosho made her debut on October 18, 2003, in a 1,400-meter race at Kyoto Racecourse. She was trained by Sakae Watanabe and ridden by Koichi Tsunoda.

She was slow out of the starting gate and began the race behind many of her rivals. That would become a familiar pattern throughout her career.

Once she reached the home straight, however, the race changed completely. Sweep Tosho accelerated past the horses in front of her and quickly opened a clear lead.

She won by three lengths.

It was only her first race, but she had already shown the weapon that would define her career: a sudden and powerful late run.

2003 Fantasy Stakes: Her First Graded Victory

Her second race was the Grade 3 Fantasy Stakes at Kyoto, again over 1,400 meters.

Sweep Tosho once more started slowly. She raced near the back while the other fillies fought for position ahead of her.

Instead of forcing her forward, Tsunoda allowed her to settle. Sweep Tosho began to improve her position around the outside before entering the home straight.

Then she produced the fastest finish in the race.

She passed her rivals and won by more than a length, completing her first two starts without defeat.

The victory established her as one of the leading two-year-old fillies in Japan. At the same time, there were already signs of the challenges to come. She could be difficult before a race, and her slow starts left her with a great deal of ground to recover.

Her talent was clear. So was her strong will.

2003 Hanshin Juvenile Fillies: Her First Defeat

Following her two victories, Sweep Tosho entered the Grade 1 Hanshin Juvenile Fillies as the favorite.

She again raced behind the leaders and tried to make her challenge in the home straight. However, her path was affected when the eventual winner, Yamanin Sucre, moved across in front of her.

Sweep Tosho continued to run and finished fifth. Despite the result, she was only 0.2 seconds behind the winner.

It was the first defeat of her career, but it did little to damage her reputation. She had not enjoyed a clear run, and the small difference between the first five horses showed how close she had come.

In January 2004, she returned in the Kobai Stakes at Kyoto. Racing from behind as usual, she produced another strong finish and won.

She now had three victories from four starts and was ready to begin her Classic campaign.

Meeting Kenichi Ikezoe

A major change came in February 2004.

Sakae Watanabe retired from training, and Sweep Tosho moved to the stable of Akio Tsurudome. Her jockey also changed.

From the Grade 3 Tulip Sho, Kenichi Ikezoe became her new partner.

Ikezoe had developed his career under Tsurudome. Taking the ride on a leading Classic hope brought considerable pressure, especially because Sweep Tosho was not an easy horse to manage.

Their first race together ended in victory.

In the Tulip Sho, Sweep Tosho settled near the back before producing her familiar late acceleration. She caught Azuma Sanders near the finish and won by half a length.

It was the beginning of a partnership that would last for almost four years.

However, their relationship was not based on Sweep Tosho becoming calm or obedient. She continued to resist human instructions throughout her career.

She sometimes refused to enter the track before a race. She disliked the starting gate. During training, she could stop and refuse to move.

Ikezoe could not simply give her an order and expect her to follow it. At times, he had no choice but to remain patient and wait until she decided to move.

He did not remove her difficult personality. He learned how to work with it.

2004 Oka Sho: A Difficult First Classic

Sweep Tosho entered the Oka Sho, the first race of the Japanese Fillies’ Triple Crown, as the second favorite.

She raced near the back and attempted to challenge in the home straight. This time, however, she could not produce enough speed to reach the leaders.

Dance in the Mood won the race, while Sweep Tosho finished fifth, 0.9 seconds behind.

It was a disappointing result after her Tulip Sho victory. Her next race, however, would bring her much closer to a Grade 1 title.

2004 Japanese Oaks: A Narrow Defeat

The Japanese Oaks was held over 2,400 meters at Tokyo Racecourse.

Sweep Tosho started as the fourth favorite. There were questions about the longer distance, but she remained relaxed near the rear of the field.

At the front, Daiwa El Cielo took control of the race. She was given a clever ride and entered the home straight with enough energy to continue.

Sweep Tosho began her challenge from behind.

She moved through the field and closed the distance with every stride. Daiwa El Cielo was still in front, but Sweep Tosho continued to gain ground as the finish approached.

The chase came too late.

Daiwa El Cielo held on by three quarters of a length. Sweep Tosho finished second.

Although she had been defeated, Sweep Tosho had proved that her late speed could remain effective over 2,400 meters. She was no longer simply a talented young miler. She had come within less than one length of winning a Classic over one and a half miles.

2004 Rose Stakes: Victory Slips Away

After a summer break, Sweep Tosho returned in the Grade 2 Rose Stakes, a trial race for the Shuka Sho.

She started as the second favorite and raced closer to the middle of the field than she had in some of her earlier races.

In the home straight, Sweep Tosho moved forward and briefly reached the front. For a moment, it appeared that she had done enough to win.

However, the race was not over.

Recle d’Or and Glorious Days finished strongly and passed her near the line. Sweep Tosho finished third, only 0.1 seconds behind the winner.

It was a frustrating defeat, but it also showed that she was ready for the final race of the Fillies’ Triple Crown.

2004 Shuka Sho: Her First Grade 1 Victory

The 2004 Shuka Sho was held over 2,000 meters on Kyoto’s inner course.

This was not an ideal course for a horse with Sweep Tosho’s racing style. The home straight was short, and a horse coming from the rear could easily run out of time.

Sweep Tosho started as the second favorite.

As the race began, she dropped almost to the very back of the field. Ikezoe did not force her to race closer to the leaders. He allowed her to find her rhythm and save her energy.

Around the third corner, he began to move her to the outside.

There were still many horses ahead of them. On the inner course at Kyoto, Sweep Tosho could not wait until the final few seconds. She needed to begin her run before entering the straight.

As the field turned for home, Yamanin Sucre moved into the lead.

Sweep Tosho was still behind, but she had begun to accelerate.

She produced the only final 600-meter time under 34 seconds in the race. One by one, the horses in front of her disappeared behind her.

Yamanin Sucre continued to fight, but Sweep Tosho was moving too quickly.

Near the finish, Sweep Tosho caught her rival and moved ahead. She won by half a length.

At last, she was a Grade 1 winner.

The victory showed the full power of her late run. It also showed that Ikezoe was willing to trust her natural racing style, even on a course where waiting near the back carried great risk.

Later that year, Sweep Tosho started as the favorite in the Queen Elizabeth II Cup but finished fifth behind Admire Groove.

Her three-year-old season had included both narrow defeats and difficult moments. But it had also produced the first major title of her career.

2005 Yasuda Kinen: Proving Herself Against Male Horses

Sweep Tosho began her four-year-old season with a fifth-place finish in the Miyako Oji Stakes.

Her next race was far more difficult: the Grade 1 Yasuda Kinen over 1,600 meters at Tokyo Racecourse.

It was her first Grade 1 race against male horses. The field included strong runners from Japan and overseas, including Hong Kong champion Silent Witness.

Sweep Tosho was only the tenth favorite.

She settled near the rear of the field and waited for the long Tokyo home straight. Ahead of her, Asakusa Den’en found a clear path and moved toward the lead.

When Ikezoe asked Sweep Tosho to run, she responded with a powerful finish.

She began to close the gap rapidly. Asakusa Den’en was still in front, but Sweep Tosho was gaining with every stride.

The two horses reached the finish in almost the same moment.

Asakusa Den’en had won by a neck. Both horses recorded the same time of 1 minute 32.3 seconds.

Sweep Tosho had not won, but her performance changed the way she had to be viewed. She had come within a neck of winning a major international mile race against male horses.

Three weeks later, she would face an even greater challenge.

2005 Takarazuka Kinen: The First Mare to Win in 39 Years

The Takarazuka Kinen is one of Japan’s two fan-voted Grand Prix races. The 2005 edition brought together many of the country’s leading horses.

Zenno Rob Roy had been named Japan’s Horse of the Year in 2004 after winning the Tenno Sho Autumn, Japan Cup, and Arima Kinen.

Tap Dance City was the winner of the previous year’s Takarazuka Kinen and had also won the Japan Cup.

Suzuka Mambo had won the Tenno Sho Spring only two months earlier.

The field also included Admire Groove, Lincoln, and Heart’s Cry.

At that point, Heart’s Cry had not yet won a Grade 1 race. However, later in 2005, he would defeat the unbeaten Triple Crown winner Deep Impact in the Arima Kinen. The following year, he would also win the Dubai Sheema Classic.

Despite finishing a neck behind the winner in the Yasuda Kinen, Sweep Tosho was only the eleventh favorite in the fifteen-horse field.

Many racing fans doubted that she could reproduce her mile performance over 2,200 meters against such strong opposition.

When the race began, Cosmo Bulk moved to the front. Tap Dance City followed close behind, while Sweep Tosho settled in the second half of the field.

She was not as far back as she had been in the Shuka Sho. Ikezoe kept her relaxed and waited for the right moment.

Around the final corner, the leading horses began to prepare for the decisive battle.

Tap Dance City was still fighting near the front. Zenno Rob Roy moved into a challenging position. The race appeared ready to become a contest between the famous male champions.

Then Sweep Tosho appeared in the center of the track.

She accelerated past Zenno Rob Roy. She passed Tap Dance City and took the lead.

For a moment, the mare who had started as the eleventh favorite was in front of Japan’s leading male horses.

But Heart’s Cry was coming from behind.

He closed the gap quickly and moved closer with every stride. Sweep Tosho had already made her long run into the lead, while Heart’s Cry was attacking late.

Neither horse gave way.

They reached the finish together, but Sweep Tosho had held on by a neck.

She had become the first mare to win the Takarazuka Kinen since Eight Crown in 1966. It was the first victory by a mare in 39 years and only the second in the history of the race.

The victory was remarkable not only because Sweep Tosho was a mare. She had defeated a field filled with proven champions and future international stars.

The horse who sometimes refused to enter the track had conquered one of Japan’s biggest races.

The horse who could not be completely controlled had defeated some of the strongest horses in the country.

2005 Queen Elizabeth II Cup: An Almost Impossible Chase

After the Takarazuka Kinen, Sweep Tosho finished sixth in the Mainichi Okan and fifth in the Tenno Sho Autumn.

She then returned to Kyoto for the Queen Elizabeth II Cup.

Osumi Haruka immediately went to the front and established a clear lead. While the other horses remained together behind her, Osumi Haruka continued to race alone.

Sweep Tosho waited near the rear.

When the field entered the home straight, Osumi Haruka was still far ahead. The finish was approaching, and it appeared that the leader might escape.

Then Sweep Tosho began her final run.

She covered the final 600 meters in 33.2 seconds, the fastest time in the race.

The distance between her and Osumi Haruka began to disappear, but the leader continued to fight. Every second mattered.

Sweep Tosho kept coming.

Just before the finish, she caught Osumi Haruka and moved ahead.

She won by half a length.

It was the third Grade 1 victory of her career and perhaps the clearest example of her explosive finishing speed.

For her performances in the Yasuda Kinen, Takarazuka Kinen, and Queen Elizabeth II Cup, Sweep Tosho was named Japan’s Best Older Filly or Mare of 2005.

She had begun the year as a talented Grade 1 winner among fillies. She ended it as a mare who had defeated elite male horses and won three major races at distances from 1,600 to 2,200 meters.

2006 Kyoto Daishoten: Victory After a Long Absence

Physical problems delayed Sweep Tosho’s return the following year.

Her difficult behavior during training also made it harder to prepare her for a race. When a horse refused to move, even a carefully planned training schedule could quickly fall apart.

Sweep Tosho did not return until the Grade 2 Kyoto Daishoten in October 2006, nearly eleven months after her Queen Elizabeth II Cup victory.

She faced male horses over 2,400 meters and started as the second favorite.

After such a long absence, it would have been understandable if she had needed a race before returning to her best. Instead, Sweep Tosho produced another powerful finish.

Fast Tateyama tried to hold on, but Sweep Tosho caught him and won by three quarters of a length.

The victory was another demonstration of her natural ability. Despite the long break and the difficulty of preparing her, she had returned with a graded victory over male opposition.

It would be the final win of her career.

Her Final Seasons on the Racecourse

After winning the Kyoto Daishoten, Sweep Tosho finished fifth in the 2006 Tenno Sho Autumn.

She then returned to the Queen Elizabeth II Cup. Kawakami Princess crossed the finish line first but was later placed twelfth for interference. Fusaichi Pandora was declared the winner, while Sweep Tosho was promoted to second place.

At the end of the year, Sweep Tosho entered the Arima Kinen and faced Deep Impact in the final race of his career. Deep Impact produced a dominant victory, while Sweep Tosho finished tenth.

She remained in training as a six-year-old in 2007.

Her first race of the year was the Victoria Mile, where she finished ninth. After another break, she returned in the Swan Stakes and finished fourth.

Her final appearance came in the 2007 Queen Elizabeth II Cup.

A new generation had arrived. Three-year-old Daiwa Scarlet controlled the race from the front and never gave the lead away.

Sweep Tosho came from behind along the inside. She could not catch Daiwa Scarlet or Fusaichi Pandora, but she finished third, only 0.3 seconds behind the winner.

Even in the last race of her career, Sweep Tosho had finished among the leading horses in a Grade 1 event.

Career Record and Major Achievements

Sweep Tosho retired with eight victories from 24 starts and career earnings of approximately 744.8 million yen.

• 24 starts, 8 wins
• 3 Grade 1 victories
• 6 graded-race victories
• 2005 JRA Award for Best Older Filly or Mare

Major Victories

• 2003 Fantasy Stakes
• 2004 Tulip Sho
• 2004 Shuka Sho
• 2005 Takarazuka Kinen
• 2005 Queen Elizabeth II Cup
• 2006 Kyoto Daishoten

She won races from 1,400 to 2,400 meters. She also finished second in the Japanese Oaks, Yasuda Kinen, and Queen Elizabeth II Cup.

Her record shows both her range and her quality. She could compete in a fast 1,600-meter race and then defeat elite male horses over 2,200 meters. Even after a break of almost eleven months, she could return and win over 2,400 meters.

A Difficult Horse and a Patient Jockey

The partnership between Sweep Tosho and Kenichi Ikezoe is an essential part of her story.

Ikezoe rode her from the 2004 Tulip Sho until the final race of her career. He was aboard for all three of her Grade 1 victories.

However, their success did not mean that Sweep Tosho became easy to manage.

She continued to refuse the track, resist the starting gate, and stop during training. On some days, Ikezoe and the stable staff had to wait until she was willing to move.

Ikezoe later described her as proud and selfish. When asked what kind of woman she would be if she were human, he suggested that she would be very difficult to date and that her partner would probably be controlled by her.

His comments were humorous, but they also reflected the reality of working with her. Sweep Tosho was never a horse whose personality could simply be removed through training.

Ikezoe did not create her talent, and he did not completely master her will. His role was to remain patient enough to give that talent a chance to appear.

Sometimes, that patience ended in frustration.

At other times, it ended with Sweep Tosho flying past Japan’s best horses.

Life as a Broodmare

After retiring from racing, Sweep Tosho became a broodmare at Tosho Farm. Following the closure of the farm, she moved to Northern Farm.

Her better-known children included Sweep Celeritas and Clean Sweep. Both won multiple races in Japan, although neither became a graded-race winner.

Her daughter Bijou Tosho did not match her mother’s achievements on the racecourse. However, she became important as a broodmare and carried Sweep Tosho’s blood into the next generation.

Sweep Tosho did not produce a racehorse equal to herself. Even so, the value of a female family cannot always be measured in a single generation.

2024 Tulip Sho: Sweep Feet Continues the Family Story

Bijou Tosho later produced a filly named Sweep Feet, sired by Suave Richard.

In 2024, Sweep Feet entered the Grade 2 Tulip Sho at Hanshin Racecourse.

Like her famous grandmother, Sweep Feet raced near the back of the field. As the horses entered the home straight, she still had many rivals ahead of her.

Then she moved to the outside and produced a powerful late run.

Under jockey Yutaka Take, Sweep Feet passed the field and won by one and a quarter lengths.

Twenty years earlier, Sweep Tosho had won the same race in her first start with Kenichi Ikezoe. Now her granddaughter had won it with a similar late-running style.

Sweep Feet went on to finish fourth in the Oka Sho. She completed her racing career in 2026 with two wins from eleven starts and became a broodmare.

She did not reach the same heights as her grandmother, but her Tulip Sho victory created a meaningful connection between two generations.

Twenty years after Sweep Tosho’s victory, her name, blood, and famous late speed had returned to the same race.

2020: Her Sudden Death

Sweep Tosho died at Northern Farm on December 5, 2020. She was 19 years old.

The cause was intestinal torsion.

Her death was sudden. According to Northern Farm, she had appeared normal until the previous day and had been living in good health while preparing for another foal.

At the time of her death, she was carrying a foal by Suave Richard.

Her passing ended the life of a mare who had remained unforgettable long after her final race.

Yet her family continued through her daughters and grandchildren, including Sweep Feet.

Conclusion: The Strong-Willed Queen

Sweep Tosho was not a perfect racehorse.

She often started slowly. Her racing style required timing and luck. Her behavior made training difficult, and sometimes the struggle began before she even entered the track.

But perfection was never the reason people loved her.

Sweep Tosho had an unmistakable personality. She would not give her cooperation easily, and she never allowed people to believe that they had completely mastered her.

When she chose to run, however, her late speed could transform a race.

She came from behind to win her first Grade 1 title in the Shuka Sho. She produced an almost impossible chase in the Queen Elizabeth II Cup. Most importantly, she defeated a powerful field of male horses in the Takarazuka Kinen and became the first mare in 39 years to win the race.

Kenichi Ikezoe never turned her into an obedient horse. Instead, he continued to work with the horse she truly was.

That may be the most important part of their story.

Sweep Tosho was not a champion because her powerful will was removed. Her strong will was part of the champion she became.

She was difficult, proud, unpredictable, and extraordinarily talented.

She was a champion who was never truly controlled.

She was accepted, trusted, and remembered.

Sweep Tosho will always remain one of the great mares of Japanese racing—the strong-willed queen who defeated Japan’s best.
