Umayuru (TV)

In real life, Vodka (2004-2019) was the daughter of Tanino Gimlet (foaled May 4, 1999).

The first ending sequence features a TP bottle and an alarm clock, two elements from the Uma Musume: Pretty Derby game. The TP bottle is used to restore the player's Toughness Points, which are required to play in Career mode. The alarm clock is used as a Continue item to redo a failed race; the player can use up to four alarm clocks in Career mode.

In real life, Daiwa Scarlet (foaled May 13, 2004) is the daughter of Agnes Tachyon (1998-2009).

A running joke throughout this series is Tanino Gimlet and her habit of destroying fences. This is in reference to the real racehorse, as he has a habit of kicking down fences at the ranch he has resided since his retirement in 2003.

Unlike the other characters, Happy Meek is an original uma musume who is not based on a racehorse. In 2022, Koichiro Yamaguchi named one of his horses Happy Meek. Unlike the character, who is designated as a stallion, the racehorse is a mare (female).

In several episodes, a giant ghostly image of Aston Machan appears in the background. The video game version of the uma musume breaks the fourth wall by telling the viewer to never forget her. This is because the real racehorse (2004-2008), who won five races in her 11-race career, was aiming to be a worthy rival to Daiwa Scarlet and Vodka, but died of Colitis X prior to the 2008 Takamatsunomiya Kinen.

Sasami Anshinzawa uses bamboo needles, which were once used on racehorses to relieve bloodstream congestion. In 2022, the Japan Racing Association (JRA) banned the use of bamboo needles, as they were proven to have no medical benefits.

The gang names in episode 12 reference historic western racehorses whose bloodlines link to the members. Brian's Bandidos is named after American racehorse Brian's Time (1985-2013), whose progeny includes Vodka, Tanino Gimlet, and Mayano Top Gun. The Sunday Syndicate consists of the descendants of American racehorse Sunday Silence (1986-2002): Daiwa Scarlet, Special Week, and Silence Suzuka. Tony's Angels, named after Irish racehorse Tony Bin (1983-2000), consists of Tosen Jordan, Air Groove, and Winning Ticket.

Daiwa Scarlet's nightmare in episode 16 references the Claw Machine mini-game, which can be randomly accessed in the Uma Musume: Pretty Derby game by selecting Recreation during the Classic or Senior season in Career mode. In the mini-game, there is a chance to grab five plushies in one round; however, it is practically impossible to collect them all, if not one, due to the combined weight of the plushies and the weakening grip of the claw.

In episode 19, Tazuna Hayakawa and Yayoi Akikawa rush to open a door. This is a direct reference to the Scout section of the Uma Musume: Pretty Derby game, where Tazuna (or sometimes Akikawa) reveals the trainee(s) the player receives from their pull.
