Japan Cup - All You Need To Know Ahead Of Ombudsman Bid

Ombudsman is set to bring the curtain down on his career in the Japan Cup at Tokyo Racecourse on Sunday 29 November, as John and Thady Gosden bid to land one of the world’s richest turf races before the Godolphin star heads to stud.

The Japan Cup is a Grade 1 open to horses aged three and upwards, run over 2,400 metres (about a mile and a half) on Tokyo’s left-handed turf course, which has a long 525-metre home straight.

The winner collects ¥500 million (around US$3.2 million) from a total purse of ¥1.09 billion. On top of that, a record US$5 million bonus is on offer this year to a horse who wins after landing a designated race such as the Champion Stakes – which Ombudsman did at Ascot last month – taking the potential haul to around US$8.2 million. 

Japan Cup 2026 Potential Runners

We take a look at some of the potential runners that could be competing for Japan Cup glory later this month...

Ombudsman (John & Thady Gosden)

Ombudsman has won ten of his 14 races and goes to Tokyo with five Group 1 wins to his name. His victories include the Prince of Wales’s Stakes in 2025 and 2026, the Juddmonte International in 2025, the Dubai Turf in March and the Champion Stakes. The latter saw him warm up for a possible tilt at the Japan Cup after beating Calandagan by three-and-three-quarter lengths last month.

The five-year-old by Night of Thunder skipped the Breeders’ Cup because the turnaround from Ascot was too short, and the six-week gap to Tokyo is seen as a better fit. 

Calandagan (Francis-Henri Graffard)

The defending champion is the horse Ombudsman will most likely have to beat. Calandagan won last year’s Japan Cup in a race-record 2:20.3, beating Masquerade Ball, having already landed the King George and the Champion Stakes in 2025 at Ascot.

The Aga Khan gelding, who was bred in Ireland and is trained in France, won the Dubai Sheema Classic in March. His connections skipped York and the Irish Champion Stakes to build his season around a second Japan Cup. He was second to Ombudsman at Ascot, but he has proven form over this course and trip and is the most obvious danger. A win would make him only the third dual winner of the race, after Gentildonna and Almond Eye.

Other European nominations

Graffard also nominated Goliath, the 2024 King George winner as a potential runner in this season's iconic world event. Aidan O’Brien put in five possible entries, which includes former Derby hero Lambourn, Minnie Hauk, Jan Brueghel and Breeders' Cup winning duo Benvenuto Cellini and Diamond Necklace. 

The home team

Japanese-trained horses have won 30 of the 45 runnings, and the home side will be strong as usual. Masquerade Ball was just touched off by Calandagan last year, and Danon Decile has won this autumn’s Tenno Sho (Autumn) at Tokyo. The full picture will become clearer when the JRA publishes its list of nominated horses on 16 November.

Japan Cup past winners

The Japan Cup was first run in 1981 to bring international stars to Tokyo, and the USA’s Mairzy Doates won the first running. Overseas horses won the early years, but Japan has dominated since. Before Calandagan’s win last year, no overseas-trained horse had won since Alkaased in 2005.

Japan’s great champions are well represented on the roll of honour. Deep Impact won in 2006, Gentildonna won in 2012 and 2013, and Almond Eye won in 2018 and 2020, setting a then-record time of 2:20.6 on her first win. Equinox won in 2023, Yutaka Take rode Do Deuce to victory in 2024, and Kitasan Black, also partnered by Take, won in 2016.

British and Irish-trained winners

Five Japan Cup winners have been trained in Britain or Ireland:

• Stanerra (1983) – Frank Dunne’s mare became the first Irish-trained winner, getting up by a head under Brian Rouse.
• Jupiter Island (1986) – Clive Brittain’s horse, ridden by Pat Eddery, became the first British-trained winner.
• Singspiel (1996) – Sir Michael Stoute’s colt, ridden by Frankie Dettori, gave the Newmarket trainer his first Japan Cup.
• Pilsudski (1997) – Stoute won again a year later, with Michael Kinane riding.
• Alkaased (2005) – Luca Cumani’s horse won in a then-record 2:22.1 under Dettori, the last British-trained winner. Ombudsman can end the 21-year wait.
