What fake identity does Jason use when first introduced? Jason is introduced as Jianyu Li, a silent Taiwanese Buddhist monk.

The identity is part of the Good Place neighborhood's original setup. Jason arrives wearing monk-like robes and maintains a vow of silence, so the other residents assume he is a deeply spiritual person. In reality, he is Jason Mendoza, a Filipino-American amateur DJ and drug dealer from Jacksonville, Florida.

Jason eventually reveals the truth to Eleanor after realizing that she also does not belong in the Good Place. His confession creates one of the series' earliest major comic twists: both Eleanor and Jason were mistakenly admitted. The name Jianyu Li is therefore not Jason's real name, but it is the identity he is using when viewers first meet him.

A common mix-up is to answer Jason Mendoza, which is his real identity. The question asks for the fake identity, making Jianyu Li the canonical answer.
