Vivian Jenna Wilson, previously known as Xavier Alexander, has reportedly moved to Japan  

Elon Musk's estranged son Xavier, who is transgender and now goes by the name Vivian Jenna Wilson, has left the US for Japan, according to the E!News media outlet.

The 20-year-old, whose mother is Musk's first wife, Justine Wilson, has reportedly relocated to Tokyo to study languages with the goal of becoming a translator, the outlet reported on Friday.

Born in 2004, Xavier is one of five children from Musk's first marriage, which ended in divorce in 2008. Xavier began his transition five years ago after coming out as transgender at the age of 16. He took his mother's last name and has said he no longer wishes "to be related to my biological father in any way, shape or form."

In an interview with Teen Vogue last week, Wilson said Musk was not involved in the decision to relocate and claimed that witnessing the "wealth gap" in Los Angeles had influenced his choice to move.

"There is no world in which people should be owning multiple private planes, private islands, private whatever, while other people are sleeping on the street," Wilson told the outlet.

Wilson claimed that Musk didn't "give a f**k," calling him a "pathetic man-child" and claiming it was "annoying" to be associated with the tech billionaire. The pair have not spoken since 2020, Wilson added. 

Last year, speaking to Canadian psychology professor Dr. Jordan Peterson, Musk argued that his son had been figuratively killed by "the woke mind virus," which the entrepreneur vowed to "destroy."

The billionaire claimed that he had been "tricked into signing documents for one of my older boys, Xavier," before he had "any understanding of what was going on."

Tesla dealerships and vehicles have come under attack in recent weeks, which Musk has attributed to his role as adviser to US President Donald Trump.

The billionaire has repeatedly circulated posts linking reports of vandalism on Teslas to trans people.

"The probability of a trans person being violent appears to be vastly higher than non-trans. Hormone injections cause extreme emotional volatility," Musk posted on X on Thursday.

Trump has rolled back pro-transgender legislation introduced during former US President Joe Biden's administration. In particular he has ordered to end federal support for medical procedures related to so-called gender transitions for people under the age of 19.
