What is the surname of Jason's character in The Good Place?

Jason’s surname in The Good Place is Mendoza. He is played by Manny Jacinto and is one of the four central human characters whose afterlife story drives the series.

Jason is introduced under the false identity of Jianyu Li, a supposedly silent Taiwanese Buddhist monk. The deception is part of the show’s early mystery: Jason, like Eleanor, believes he was mistakenly admitted to the Good Place. In reality, he is Jason Mendoza, a deceased amateur DJ and small-time drug dealer from Jacksonville, Florida.

Jason is cheerful, impulsive, immature, and often gloriously confused, but he is also kindhearted and capable of genuine loyalty. His closest friendship is with Pillboi, his former partner in crime, while his supernatural soulmate is Tahani Al-Jamil. Viewers sometimes confuse Jason’s surname with the names of other characters: Chidi Anagonye, Tahani’s sister Kamilah Al-Jamil, and Eleanor Shellstrop. Mendoza is Jason’s actual identity, not part of his monk disguise.
