The 8.9-magnitude earthquake and resulting tsunami that devastated Japan on Friday have wreaked havoc on Japan’s racing industry — but according to early reports, most of the nation’s prized equines, including several American champions, appear to be safe.

The nation’s largest-ever earthquake, with an epicenter off the eastern coast of the country, appears to have spared the northern island of Hokkaido, where most of Japan’s prominent breeding farms are located.

The Shadai Stallion Station reported only light damage and said its horses were uninjured. The stallion complex is home to 2002 Kentucky Derby and Preakness winner War Emblem; Japanese Triple Crown winner Deep Impact; Japan Cup winner Falbrav; leading sire Zenno Rob Roy; and international standouts Harbinger and Heart’s Cry. The farm’s broodmare band is loaded with American Grade 1 winners and producers, including Lucky One, dam of Kentucky Oaks and Alabama winner Blind Luck.

International breeding and racing power Darley also reported that the horses at its Japanese stallion station were unharmed. Darley stands Forego winner Pyro, Japan Cup winner and Horse of the Year Admire Moon and Breeders’ Cup Turf winner Fantastic Light in Japan.

Although no official statements have been issued, reports through social media sites indicate that other major farms on Hokkaido, including Northern Farm, the Iburai Stallion Station and the Shizunai Stallion Station, escaped serious damage or injury to horses. Northern Farm, owned by leading breeder Katsumi Yoshida, is home to a number of American Grade 1 winners in its broodmare band, among them 2002 Horse of the Year Azeri and 2007 Breeders’ Cup Distaff winner and Eclipse champion Ginger Punch. Iburai houses dual classic winners Charismatic and Silver Charm, Dubai World Cup winner Captain Steve and Breeders’ Cup Sprint winner Squirtle Squirt. Shizunai is home to Eclipse champion Boston Harbor, Santa Anita Derby and Pacific Classic winner Came Home, Belmont winner Empire Maker, French standout Bago, multiple Group 1 winner David Junior, and Breeders’ Cup Turf winner and Canadian champion Chief Bearhart.

Unsurprisingly, the earthquake has scrapped Japan’s racing schedule for the weekend, and the cancellations could stretch into the next week and beyond. Four graded stakes races scheduled for the weekend — including the Grade 2 Hochi Hai Fillies Revue, a key prep for the Japanese 1000 Guineas — are in flux, with no reschedule dates announced yet.

The quake struck toward the end of the card at Japan’s National Association of Racing track in Ohi, east of Tokyo — causing those in the stands to stampede to safety. The final three races on the 12-race card were lost.

The Japan Racing Association canceled racing at Fukushima Racecourse in Fukushima City, which incurred severe damage, with part of the roof of the structure collapsing. More frighteningly, the track is located in the same region as a Fukushima nuclear power plant that suffered a breakdown in its cooling system as a result of the damage. With pressure rising, the area around the plant has been evacuated.

Part of the roof collapsed at the National Association of Racing track in Mizusawa and minor damage was also reported at Tokyo Racecourse.

In Sendai, which was hard-hit by the devastation, a number of training centers were severely damaged. There have been no reports yet as to if any horses were lost, and if so, who they are.
