Shinzan

Two-year-old season (1963)

Shinzan took part in his maiden race in November, 1963, a week later than originally planned because he would have competed against another colt of Hindostan, Umeno Chikara, who was highly anticipated at the time; Shinzan's trainer, Takeda, believed Shinzan wouldn't stand a chance against him.^[1]

Three-year-old season (1964)

Despite winning four races in a row leading up to January, Takeda continued to have a relatively low opinion of the horse. Soon after those four consecutive wins, Shinzan was found bleeding from a hind leg after training one morning; the cause was found to be the horse working his hind legs so hard that they knocked against his front horseshoes. After a discussion with veterinarians and farriers, a special type of horseshoe was made for him to prevent these collisions. While it couldn't be used in official races, it helped break the horse in without fear of injury.^[1]

Shinzan contested the Spring Stakes on March 29 against a lineup of prominent racehorses, including Umeno Chikara and Tokino Parade (winner of the Keisei Hai and Yayoi Sho). Shinzan hadn't taken part in any races that served as direct stepping stones to the Classics, a fact reflected in being the sixth-favorite in the polls. Nevertheless, he sharply accelerated on the final straight to win by half a length. His trainer, Takeda, hadn't even come to Tokyo to see the race, assuming it was hopeless; it's reported that he apologized directly to Shinzan for not recognizing the horse's potential.^[1]

Shinzan's next race was the Satsuki Shō, the first of the three Classic Triple Crown races and one of the big eight races in Japanese horse racing. It was held at Tokyo Racecourse because its normal Nakayama Racecourse venue was undergoing renovations at the time. After his previous performance, Shinzan was considered the number-one favorite. He dashed up towards the front at the start of the race, then fell back to the middle pack before surging on the final straight to win the race by 3/4 lengths, earning his first crown.^[1]

Before the Tōkyō Yūshun (Japanese Derby), he was entered into an open race, where he lost for the first time, coming in 2nd, seemingly due to being slightly heavier.^[1] He lost seven kilograms ahead of the Derby, which he entered as the number-one favorite with 2.1 odds. Out of the 27 horses in the field, Shinzan started in the fourth bracket, considered an extremely good starting point. Like before, he stayed in the midfield before accelerating on the third corner to pull into the lead. Umeno Chikara passed him on the inside, managing to pull a full length ahead. Shinzan sped up again, coming up alongside Umeno Chikara at around the 100-meter mark, then accelerated to win by 1 1/4 lengths. After the race, his jockey Kurita commented that "I ran him knowing it would be my responsibility if he lost. (But) It was easier than with Kodama [a double-crown winner from 1960]." Meanwhile, Takeo Ito, who jockeyed Umeno Chikara, admitted to his defeat, saying "The race went exactly the way we wanted and we still lost. Shinzan is strong. I have no regrets."^[1]

Having attained two of three crowns, Shinzan's team eschewed the normal practice of staying in Hokkaido for the summer, opting instead to continue training at the stable. However, it was reportedly hotter that summer than it had been in decades. Shinzan seemed to suffer because of the heat, and despite various attempts by Takeda and others, they weren't able to train the horse properly until after September as autumn arrived. He entered an open race on October 10, where he lost a second time, taking second place to underdog Ichimikado. Then, at the Keisei Hai, he was defeated by Ballymoss Nisei. These results seemed to signal a poor performance at the Kikuka Sho, the final of the three Triple Crown races, but just before the race the horse made a rapid recovery.^[1]

Shinzan came into the Kikuka Sho on November 15 as the second favorite behind Umeno Chikara, who had swept the St Lite Kinen, a preliminary race. Umeno Chikara had 39.9% odds to win, while Shinzan had 31.6%, dominating the rest of the field. Takeda told Kurita not to press the attack even if it cost him the victory, believing that whoever pressed first would lose. However, as the race began, Kanekeyaki (two-crown winner of the fillies' Oka Sho and Yushun Himba) stole the lead and broke away from the field. She created a gap of over 20 lengths from Shinzan and Umeno Chikara, who were in the middle of the pack. However, Kanekeyaki slowed as she rounded the third corner on the second lap, allowing the trailing horses to catch up. Near the end of the race, Umeno Chikara--who had been right behind Shinzan for the entire race--pushed forward, aiming to pass Kanekeyaki. Kurita waited another moment before accelerating. Shinzan swung wide on the last turn and passed the rest of the pack, comfortably winning his third crown. The win made Shinzan the first horse to win the Triple Crown since St Lite in 1941.^[1]

Shinzan was then expected to contest the year-end Arima Kinen, but the horse's exhaustion after the Kikuka Sho lingered. Takeda decided not to enter the horse into it in consideration of the previous summer's heat and the horse's accomplishments and rest him instead.^[1]

Four-year-old season (1965)

Shinzan was initially scheduled to enter the spring Tennō Shō, but Takeda canceled his participation because while the horse's fatigue had cleared, one of his hooves became inflamed; during this time, he couldn't be trained to Takeda's satisfaction, nor would he eat much fodder. Takeda decided to continue letting Shinzan rest until the Takarazuka Kinen on May 29. (The Takarazuka Kinen was not counted as one of the eight most important races at the time, so this win was not considered to be another "crown" for Shinzan.)^[1]

Despite it having been about half a year since racing last, Shinzan won the race, then followed it up with an open race win on June 13. This performance placed him at the top of the fan votes for the Takarazuka Kinen. The track was in poor condition, a first for Shinzan, but he swung wide on the final straight, surging up from fourth place to defeat Ballymoss Nisei by half a length.^[1]

Shinzan once again spent the summer in the stable, but the average heat that year combined with better preparations led Takeda to continue to train him normally through the season. However, after contracting horse flu at the beginning of autumn, Shinzan was barred from going to Tokyo. Instead, Takeda opted for the Meguro Kinen, a handicap race. He worried about the handicap--63 kilograms of weight--but Shinzan won by half a length over the competent Bull Takachiho.^[1]

Shinzan entered the autumn Tenno Sho with a 1.0x payout. His main rival in the race was Haku Zuiko, who had won 9 of his 10 races. The race began with Miharukasu running at the front, with Shinzan, Haku Zuiko, Bull Takachiho, and Umeno Chikara waiting until the final stretch to accelerate. There, Shinzan came from the outside and Haku Zuiko from the inside. Ultimately, Shinzan won by two lengths, earning a fourth crown.^[1]

The last of the big eight races that Shinzan was eligible for but hadn't won yet was now the Arima Kinen, which he entered and contested on December 26. Nakayama Racecourse was still damp from rain, making for poor conditions on the track. As the race began, Miharukasu (3rd in the autumn Tenno Sho) ran at the front, while Shinzan maintained a third-place position. By the third corner, Miharukasu had pulled away by seven or eight lengths, but as he turned onto the final straight, he suddenly took a far-outside route to try and avoid the much rougher inside line. This was also an attempt by his jockey, Takemi Kaga, to force Shinzan onto the inside line and slow him down. However, Shinzan then swung even further outside than Miharukasu, almost right up against the outside fence, causing him to be out of view of the audience. The television cameras also lost sight of him for a moment, causing the commentator to cry "Shinzan disappeared!" Shinzan ultimately won the race, earning his fifth and final crown, becoming the first horse to do so. After the race, Yoshito Matsumoto--who had ridden Shinzan instead of Kurita--commented that "Shinzan told me to go outside." Shinzan was retired after this race.^[1]
