In a recent birthday post for the character Yamato, Toei Animation unexpectedly used a pronoun that sparked controversy. The original caption read: “Each post celebrates Yamato’s spirit of freedom on his birthday.”
However, shortly after, the caption was edited to remove the phrase “on his birthday” and replaced with a more neutral term, “today.”
This change immediately caught the attention of the One Piece fan community. Many wondered why Toei didn’t simply change “his” to “her,” but instead chose to remove the pronoun altogether. This move reignited ongoing debates within the fandom about Yamato’s gender identity.

Yamato’s gender and identity have long been a hot topic among fans, with opinions divided.
Some fans point out: “From the first appearance in both anime and manga, Yamato was introduced as Kaido’s daughter, nicknamed the Demon Princess, and listed as female on the Vivre Card.”
Others argue: “Whether male or female, Yamato only cares about becoming Oden,” or “Yamato always sees themselves as a reincarnation of Kozuki Oden. Toei’s wording might reflect the character’s self-identification as male, since Oden was male.”
This incident has led fans to question whether Toei’s post was an indirect confirmation of Yamato’s male identity or simply a social media typo.
If Toei considered Yamato simply female, changing “his” to “her” would have been the easiest fix. Instead, opting for a neutral term suggests Toei is trying to avoid controversy and respect the complexity of Yamato’s gender identity.
Ultimately, this is a common story within the One Piece fandom, where Yamato identifies as Oden and focuses on freedom, with biological gender seeming less important.
