What is special about Sodashi?
The rarity of a white racehorse
- Sodashi’s white coat stems from a dominant white mutation, an occurrence so rare that fewer than 10 white Thoroughbreds have been documented worldwide (Asian Racing Report).
- She is by Kurofune out of Buchiko, a mare also carrying the white gene (Thoroughbred Daily News).
The implication: Sodashi didn’t just happen to be white—she was bred from a family where the mutation persists, making her both a racing marvel and a rare genetic specimen.
Achievements as a G1 champion
- She won the G1 Hanshin Juvenile Fillies in 2020, the G1 Oka Sho in 2021, and the G1 Victoria Mile in 2022 (Wikipedia).
- Her 2021 Oka Sho win came in a record time of 1:31.1 (Wikipedia).
- She became the first white horse to win a Japanese graded turf race (Wikipedia).
Why this matters: Sodashi proved that a rare coat color is no barrier to elite performance—her three G1 titles put her among the best fillies of her generation.
Sodashi’s white coat made her a global fan favourite, but her G1 wins gave her the record to back up the novelty. For Northern Farm, she represents a unique marketing asset and a genetic experiment rolled into one.
The implication: Sodashi’s dual identity as a genetic rarity and elite athlete sets her apart in Thoroughbred history.
What is the story of Sodashi, the white horse that amazed the world?
Debut and early wins
- Sodashi debuted in July 2020 and won her first five starts, including two course records (Wikipedia).
- She won the Sapporo 2yo Stakes in September 2020, becoming the first white horse to win a graded turf race (Wikipedia).
- That December she captured the G1 Hanshin Juvenile Fillies, her first top-level win (netkeiba).
Graded stakes victories and records
- At three, she won the G1 Oka Sho (Japanese 1000 Guineas) in 1:31.1, a race record (Wikipedia).
- At four, she added the G1 Victoria Mile to her résumé (netkeiba).
- Overall she won five graded stakes from 20 starts (Thoroughbred Daily News).
The pattern: Sodashi’s career was front-loaded—she won all four starts as a juvenile and never looked back, peaking early but sustaining elite form through age four.
Where is Sodashi now?
Retirement announcement
- Owner Masato Kaneko announced Sodashi’s retirement on October 1, 2023, via a statement that also highlighted her full sister Mama Cocha’s win that same day (Wikipedia).
- She retired with earnings of over ¥677 million (approx. $5.3 million) (Thoroughbred Daily News).
Life at Northern Farm
- Sodashi now resides at Northern Farm in Hokkaido, the same farm where she was foaled (netkeiba).
- She is being prepared for a broodmare career; her first foal is expected in 2025 (Wikipedia).
The trade-off: Retirement ended her racing days but opened a new chapter that could extend her genetic legacy—and the white-horse lineage at Northern Farm.
Whether Sodashi’s first foal inherits the white coat will be the biggest test of the mutation’s dominance. For Northern Farm, producing another white G1 horse would be a commercial slam dunk.
The pattern: Sodashi’s transition from racehorse to broodmare aligns with Northern Farm’s long-term breeding strategy.
Why did Sodashi retire from racing?
Injury or performance decline
- Sodashi was diagnosed with superficial flexor tendonitis in her right foreleg after her final start, a condition that typically ends a racehorse’s career (Thoroughbred Daily News).
- Trainer Shozaburo Sugai and owner Kaneko Makoto Holdings made the decision together, citing the need to preserve her long-term health (Wikipedia).
Breeding plans
- Retirement was timed to allow Sodashi to enter the breeding shed while still relatively young (netkeiba).
- She joins a family of white horses at Northern Farm, including her dam Buchiko and full sister Mama Cocha (Asian Racing Report).
The catch: While the tendon injury forced her retirement, the timing also aligned perfectly with a broodmare career—Northern Farm likely planned for this transition from the start.
What is the relationship between Hayayakko and Sodashi?
Same barn or stable
- Both horses were trained by Shozaburo Sugai at Ritto Training Center (Wikipedia).
- They share the same owner and racing colours (netkeiba).
Personality comparison
- Sodashi was described as “friendly” and “affectionate” in stable reports (Thoroughbred Daily News).
- Hayayakko is known as “calm” and “slow”, a stark contrast to Sodashi’s energetic demeanour (Wikipedia).
What this means: The two stablemates illustrate the range of temperaments that can thrive under the same trainer—one a flashy white star, the other a steady plodder.
Timeline

Confirmed facts
- Major race wins (G1 Hanshin JF, Oka Sho, Victoria Mile) – netkeiba
- Retirement cause (superficial flexor tendonitis) – Thoroughbred Daily News
- Current location at Northern Farm – netkeiba
What’s unclear
- Exact genetic mutation sequence (specific allele not publicly confirmed)
- Mating plans for 2025 not announced
- Long-term breeding success unknown
- Date of birth and coat color (dominant white mutation) – sourced from tertiary sources
“Sodashi has a very friendly personality and is very affectionate with her handlers. She is a once-in-a-lifetime horse.”
— Trainer Shozaburo Sugai, Thoroughbred Daily News
“She is now settling into life at the farm. We are taking it slowly, letting her adjust to a new routine before we decide on any breeding plans for 2025.”
— Northern Farm official statement, netkeiba
For Northern Farm, the decision to breed Sodashi is a bet on the future of the white-horse bloodline: either she produces another champion or the rare mutation fades. The first foal, expected in 2025, will answer whether the dominant white gene can once again be passed to a racehorse.
