Japan presents an apparent contradiction.

Using an overseas online casino from inside the country can result in criminal investigation. Yet an adult can legally open a JRA account, deposit money and bet on horse races from the same telephone.

The easiest explanation is legal: Japan’s Horse Racing Act creates a specific exception to the country’s general prohibition of gambling.

But that does not explain why horse racing received the exception—or why Japanese society treats 競馬 — keiba, horse racing, differently from an online casino.

The answer begins before JRA existed and before Japan established its modern gambling restrictions.

Modern horse racing appeared in Japan in 1862, when foreign residents organised races in Yokohama. Betting was later offered at Negishi Racecourse, while Japanese racing clubs began selling tickets with the government’s informal approval in 1906.

Racing did not initially arrive as an underground game. It came attached to Western modernity: formal competition, purpose-built venues, imported thoroughbreds and elite social participation.

That distinction did not protect it indefinitely.

The rapid proliferation of racing clubs and growing enthusiasm for betting produced visible social problems. When Japan’s new Penal Code entered into force in 1908, the government prohibited the sale of betting tickets.

This should have ended the industry. Instead, the state helped keep it alive.

Without betting revenue, racing struggled to finance itself. But the government and agricultural authorities still considered organised racing useful.

At the time, horses remained important for farming, transportation and military purposes. Racing provided a system for testing performance, encouraging breeding and improving the country’s horse population.

Industry representatives therefore argued that Japan could not sustain better horses without financially sustainable races.

The government accepted that reasoning. The original Horse Racing Act was enacted in 1923, restoring regulated betting to support the improvement and production of horses.

This is the central reason horse racing escaped Japan’s gambling restrictions:

Horse racing became useful before it became broadly respectable.

The state gradually tightened its control.

Japan’s regional racing clubs were consolidated into the Japan Racing Society in 1936. After the Second World War, central racing was temporarily operated by the national government. In 1954, the Japan Racing Association—日本中央競馬会, better known as JRA—was created to inherit that system.

JRA was not designed as a normal private bookmaker. It became a government-funded special corporation supervised by the Ministry of Agriculture, Forestry and Fisheries.

This institutional structure separated racing from ordinary gambling. The state controlled who could organise it, how tickets were sold, how races were supervised and where part of the proceeds went.

But legislation alone cannot create cultural legitimacy. Racing also had to become something people could follow without defining themselves primarily as gamblers.

Japanese racing developed its own calendar, heroes, statistics, bloodlines and generational stories.

The 日本ダービー — Japan Derby, first held in 1932, became known as keiba no saiten: the festival of horse racing. Its 1990 edition attracted 196,517 spectators, still the attendance record for central racing.

Races such as the 天皇賞 — Tenno Sho, Japan Cup and 有馬記念 — Arima Kinen became national sporting occasions. Famous horses acquired fan bases extending beyond regular bettors. Their careers, rivalries and descendants gave audiences reasons to participate that were not reducible to the next wager.

The Japan Cup added another dimension. Created in 1981, it was intended to measure Japanese horses against leading international competition. Early defeats demonstrated the gap in quality; later Japanese victories became evidence that the country’s breeding industry had reached the world’s highest level.

In this environment, betting remained highly visible, but it was surrounded by the language and rituals of sport.

A casino game begins again after every result. Horse racing creates a continuing narrative: the development of a young horse, its pedigree, its trainer, its jockey and its place within racing history.

That does not make the wager less real. It gives the wager a cultural structure that many other gambling products lack.

Hong Kong suggests this development is not uniquely Japanese.

Racing began at Happy Valley in 1846, while the Hong Kong Jockey Club was founded in 1884. Over more than a century, the club became simultaneously a racing authority, membership institution, major taxpayer and charitable funder.

Hong Kong did not accept horse betting because it considered gambling harmless. Racing had existed long enough to become part of the city’s social infrastructure.

Japan followed a different political path, but the underlying pattern was similar:

The historical distinction is becoming less visible to the customer.

In 2025, telephone and internet channels accounted for 81.1% of JRA’s central horse-racing ticket sales. Most betting no longer requires the architecture, crowds or ceremony of a racecourse.

The legal institution remains the same, but the user experience increasingly resembles other forms of digital gambling: open an account, select a market and place a wager.

This does not make JRA equivalent to an illegal online casino. It does, however, weaken the cultural separation that helped racing appear fundamentally different.

Horse racing is not legal in Japan because betting on horses is inherently safer or morally superior.

It is legal because racing arrived as organised sport, became useful to national horse policy and developed into a controlled institution before Japan’s modern gambling regime was fully formed.

Decades of famous races, champion horses and international success subsequently gave it cultural legitimacy that legislation alone could never manufacture.

By the time Japan built its present boundaries around gambling, horse racing was already too established—and too useful—to treat as an ordinary vice.

Its survival is therefore not simply a legal exception.

It is the result of history arriving first.
