Abe's original name was Li Zhendong (李振冬); after he moved to Japan at age 9, he changed to using his present name.

In April 29, 2009 Abe told reporters that he and Chinese actress Shi Ke (史可) have tied the knot.

They reportedly started dating after the shooting in 2006 of the Chinese film Stand In Love.

[1][2] In August 2017, Japanese publications Josei Seven and NEWS Post Seven alleged that in 2014, Abe had been engaged in an affair with Takako Uehara, herself married to Tenn (MC) at the time.

Supporting documents shared with the publications by Tenn's family include his suicide note referencing the affair, and photographs from Tenn's phone of chat transcripts between Uehara and Abe.
