Hakuryo

Hakuryo was foaled on May 6, 1950, at Morita Farm in Aomori Prefecture, where his dam had been sent from Yashima Bokujo.^[2] His childhood name was Yashima Beauty.^[2] He was sired by Primero, and his dam was Dai-yon Buchanum Beauty, a daughter of Diolite.^[2] His full siblings included New Moana, who won the 1952 Mainichi Okan, and Shirahata, who won the Fukushima Kinen and later became the dam of Meiji Hikari.^[2] Among his contemporaries bred at Yashima Bokujo were Bostonian and Tokitsu.^[2]

Hakuryo was purchased by Hiroshi Nishi and trained by Tokichi Ogata.^[1] The name "Hakuryo" is derived from a fisherman in the Noh play Hagoromo.^[3] He measured 172 cm in height and 194 cm in girth, which was large for a Japanese racehorse of the 1950s.^[2][4] This build contributed to chronic quarter cracks that affected him throughout his career.^[4]

The following table details all 25 starts of Hakuryo's racing career based on official JRA historical records.

Hakuryo stood at Wakakusa Farm in Hokkaido for three years before moving to the Urakawa Stallion Station.^[2] During this period, domestic stallions were generally less favored due to the influx of foreign imports, but Hakuryo sired multiple stakes winners.^[2] He ranked in the top ten of the Japanese general sire list seven times, peaking at fourth in 1964.^[2] He died of old age on September 4, 1975, at the age of 25, and was buried at Urakawa Minota Farm.^[2]

Jockey Takao Yasuda, who rode both Hakuryo and Hakuchikara, stated that Hakuryo possessed more speed and power than Hakuchikara, and that his front-running style would have been suited to American racing.^[2][4] Trainer Tokichi Ogata noted that few horses of the era matched Hakuryo's physical build.^[2] Hiroshi Nishi's wife later stated that Nishi had originally intended to send Hakuryo, rather than Hakuchikara, to compete in the United States.^[4]
