From Japan's Racetracks to Imperial Duty: The Horses Carrying Diplomacy Forward

Fourteen horses, twelve former racers

Fourteen horses serve in Japan's Imperial Guard, and 12 of them once raced on the country's tracks. On the grounds of the Imperial Palace in central Tokyo, these former athletes now carry guards and escort carriages taking newly appointed foreign ambassadors to meet the Emperor.

Their new work rewards qualities that a race result cannot measure. A horse that never won can become a trusted diplomatic escort, provided it stays calm around crowds, traffic and unexpected noise. The change requires careful selection and extensive retraining, replacing the speed of the racetrack with the patience of ceremonial service.

The palace horses also help teach new guards to ride. Their working lives can continue well into their twenties, offering a long and secure second career after a racing career that often ends much earlier.

Japan's Imperial family has a connection with horses that reaches beyond these official duties. Emperor Naruhito and Empress Masako know individual animals by name, while earlier generations rode from childhood. The relationship also reaches back to ancient court rituals and the Meiji era, when horses helped express Japan's modernization and welcome foreign visitors.

The small Imperial stable sits within a much larger challenge. About 6,000 racehorses retire in Japan each year, and finding places for them is difficult. The palace offers a striking example of what retraining can achieve, while the scale of retirement across the country demands many more homes and opportunities.

What makes a horse suitable for the guard?

Mitsuru Sato, the official responsible for the escort horses, has worked with the Imperial horses for 35 years. His central concern is temperament: an animal must be calm, reliable and comfortable with people.

Tokyo's streets make those qualities essential. A horse escorting an ambassador cannot easily become frightened by movement or noise around it. Racing experience can help because the animals are already familiar with human handling, but the ability to remain composed is what matters most in their new role.

Sato also keeps traditional beliefs about horses in mind. One says that a single white sock on the left hind leg indicates a fine horse. Another associates a double whorl on the forehead, where the hair grows in two circular patterns, with a nervous disposition. These sayings are part of the selection process without being taken as literal rules.

Physical appearance is therefore less important than character. A distinguished pedigree or an impressive racing record cannot replace the steady behavior needed to follow a rider's instructions in a busy public setting.

Learning a different kind of discipline

Horses often arrive at the Imperial stables at four or five years old, after leaving racing. Training begins with helping them settle into surroundings very different from a noisy racetrack: the quiet, historic grounds of the Imperial Palace.

Sato and the other trainers introduce the work gradually. Nobody rides a newly arrived horse until the trainers consider it safe. The adjustment gives the animal time to become familiar with its new home before taking on further demands.

A horse that is easy to ride can give an inexperienced guard confidence and help that rider improve quickly. Teaching recruits is considered just as important as appearing in a state ceremony. The animal becomes both a working escort and a dependable partner for someone learning the job.

Every morning, the horses are led to a nearby riding arena to walk, canter and jump. Cantering is a pace faster than walking but more controlled than a racing gallop. Jumping helps trainers check that the horses respond precisely to instructions, even though their ceremonial duties do not require them to clear obstacles.

The horses return to the stables for showers and hoof care after exercise. This regular cycle of training and care continues into their twenties, keeping them prepared for both public duties and the quieter work of helping guards learn.

An ambassador's journey through Tokyo

Newly appointed ambassadors can travel by carriage from Tokyo Station to the Imperial Palace to present their credentials to the Emperor. Credentials are the formal documents identifying them as their country's diplomatic representative. Mounted guards escort the carriage through the capital.

The tradition resumed in 1952 after World War II. Ambassadors are often given a choice between a car and a carriage, and most choose the carriage as a distinctive and prestigious introduction to Japanese culture.

Kazuhiko Akinaga, a curator at the Equine Museum of Japan, identifies Japan as one of only a few countries that maintain this traditional transport for diplomats. The United Kingdom and Spain are among the other examples he gives.

The journey takes the horses away from peaceful palace grounds and into streets surrounded by tall buildings and large crowds. A plastic bag carried by the wind or a sudden siren can frighten an animal. An escort horse must continue responding to its rider through those distractions.

Daily training prepares the animals for that contrast. Their suitability depends on both their natural character and their ability to follow instructions when the surroundings become unfamiliar or noisy.

Yukikaze's value goes beyond winning

Yukikaze, an 11-year-old male horse, illustrates how different the demands of racing and Imperial service can be. His father, Special Week, won four Grade 1 races, including the Emperor's Cup in 1999. Grade 1 denotes the highest level of racing competition.

Yukikaze raced under the name Yukino Dream, making eight starts without a win. He joined the Imperial barn at five years old. His main duty now is to trot steadily alongside the ambassador's carriage, where patience and consistency matter more than speed.

Sato, the official responsible for the escort horses, describes Yukikaze's temperament in simple terms:

He's timid and docile,

During a training session in December, Yukikaze initially skirted an obstacle after Sato raised the bar. With encouragement, he cleared it on his second attempt. His cautious nature fits work that calls for a steady response rather than a rush forward.

The contrast between his famous father and his own modest race record makes his second career especially telling. The Imperial Guard has given him a role suited to his character, rather than one judged by his ability to win.

The other horses behind the ceremony

Shōyū, a 16-year-old veteran of the Imperial Guard, joined after retiring from racing at four. Sato first saw him at a riding club owned by an acquaintance and rode him immediately.

Sato recalled recognizing at once that Shōyū had the qualities needed for the guard:

I knew immediately that he was the horse for the job,

Shōyū has been a reliable member of the team ever since. His long service reflects the importance of finding an animal whose temperament suits the work from the beginning.

The stable also houses Hakurei, a nine-year-old white horse who previously raced as Maillot Blanc. Another resident is Aokaze, a 23-year-old son of the Imperial Cup winner Bubble Gum Fellow.

These horses span different ages, racing histories and personalities. Together, they show how the stable draws on former racers for years of service, with older animals continuing to contribute alongside younger arrivals.

A personal connection with the Imperial family

Emperor Naruhito and Empress Masako's interest in horses became evident during an Imperial garden party in autumn 2025. Speaking with star jockey Yutaka Take, they mentioned numerous racehorses by name and discussed Hakurei, the white horse serving in the Imperial Guard.

Take observed that many white horses can be rough by nature. Empress Masako described Hakurei's individual personality:

goes pretty much his own way,

Emperor Naruhito added his own observation about the differences between animals:

Every horse is different.

Take was amazed by how smoothly the Imperial couple recalled the horses' names. After the party, the jockey described the impression their conversation had left:

I felt that they really love horses,

At a press conference in February, Emperor Naruhito spoke of looking forward to seeing the horses during his regular walks around the palace grounds. His interest is part of a family connection extending across generations.

The Emperor Emeritus captained his school's equestrian society in his youth. Emperor Naruhito and Crown Prince Akishino have also been familiar with horses since childhood. The animals are therefore part of the family's personal experience as well as its ceremonial life.

From ancient court rituals to modern diplomacy

Horses have appeared in rituals and events at Japan's Imperial court since ancient times. Their role changed during the Meiji era, from 1868 to 1912, when Japan underwent rapid modernization.

Emperor Meiji adopted horses as a principal means of transport and rode to inspect different regions of the country. In March 1874, he watched a horse race for the first time at a temporary Imperial residence in Akasaka. He subsequently attended more than 50 events connected with racing.

In 1905, Emperor Meiji gave a vase bearing the Imperial chrysanthemum crest to a racecourse in Yokohama's Negishi district as a trophy. That gift marked the establishment of the Emperor Cup horse race, which continues as one of Japan's most prestigious racing events.

Akinaga, the Equine Museum of Japan curator, explains Meiji's support for racing as a deliberate political act. By embracing a form of Western culture, the Emperor showed audiences at home and abroad that Japan had modernized. Equestrian events also provided occasions to entertain diplomatic delegations and build international friendships.

The history of horses in Imperial life includes several distinct milestones:

• Ancient times: horses were used in rituals and events at the Imperial court.
• 1868 to 1912: during the Meiji era, Emperor Meiji used horses for transport while inspecting regions of Japan.
• March 1874: Emperor Meiji first watched a horse race at a temporary Imperial residence in Akasaka.
• 1905: his gift of a trophy bearing the chrysanthemum crest marked the establishment of the Emperor Cup race.
• 1952: carriage journeys for ambassadors resumed after World War II.
• Autumn 2025: Emperor Naruhito and Empress Masako discussed racehorses and Hakurei with jockey Yutaka Take at an Imperial garden party.

The carriage escort carries that diplomatic connection into modern Tokyo. Horses remain part of how Japan formally welcomes representatives of other countries, even as cars provide an alternative.

A much larger retirement challenge

Nearly 8,000 foals are born annually in Japan's large racing industry, and about 6,000 racehorses retire each year. Their racing careers typically end between three and six years of age, while their natural lifespan is 25 to 30 years.

Those figures explain the length of the care commitment after racing. A horse leaving the track at a young age may need a home, food and attention for roughly two more decades. Upkeep can exceed 100,000 yen a month, making long term care expensive.

Japan also has fewer riding clubs than Europe, limiting opportunities for former racers to become riding horses. Few retired animals move into riding or breeding roles. Many are sent to abattoirs, where their meat becomes a delicacy in some circles.

Organizations such as Thoroughbred Aftercare and Welfare provide temporary care and retraining. Their facilities, however, can accommodate only a small number of animals. Retraining creates opportunities, but it also requires suitable horses, people, space and continuing care.

Horse Trust in Kagoshima Prefecture offers a different kind of home: a permanent sanctuary for about 150 retired horses. Its approach allows animals to live in herds and have freedom of choice in their daily activities.

The Imperial Guard's 12 former racehorses are a small group beside the roughly 6,000 animals retiring annually. Their successful transition nevertheless shows the potential for horses accustomed to people and disciplined training to take on useful work beyond the track.

Horse stories reach beyond the palace

Haru Urara became one of Japan's best known examples of affection for a horse without a winning record. She failed to win in 113 starts and became known as the "shining star of losers." Her resilience won public affection despite her results.

Her story later inspired a character in the game and anime franchise Uma Musume: Pretty Derby. The franchise turns famous racehorses into fictional horse girls, carrying names and stories from racing into another form of entertainment.

Uma Musume has also collaborated with other media, including a recent partnership with a television drama about the racing world. Such connections keep horses and their histories in public view beyond race meetings.

The Imperial couple's interest extends beyond Japanese racing. During a visit to Mongolia, Emperor Naruhito and Empress Masako attended the Naadam festival and watched traditional horse racing on the prairie. They used binoculars to follow the race, showing their appreciation for another country's equestrian traditions.

Haru Urara's popularity and the Imperial Guard's former racers reveal different ways horses can find recognition beyond victories. One became a cultural favorite through repeated defeats; others found new work through calmness, reliability and their relationships with people.
