On October 14, 2013, Daniel, along with
Rolles Gracie, Jr., made an appearance for
professional wrestling promotion
New Japan Pro-Wrestling (NJPW) at the
King of Pro-Wrestling pay-per-view, issuing an open challenge for the January 4, 2014,
Wrestle Kingdom 8 in Tokyo Dome event, which was later answered by
Yuji Nagata and
Kazushi Sakuraba, the latter known as the "Gracie Hunter" for his MMA bouts with members of the Gracie family. The Gracies lost the match via disqualification, after Rolles choked Nagata out with his gi. A rematch between the two teams took place on February 11 at
The New Beginning in Osaka and saw Rolles submit Sakuraba for the win. On April 6 at
Invasion Attack 2014, the Gracies defeated
Takashi Iizuka and
Toru Yano in another tag team match. Later in the event, Daniel entered the
IWGP Intercontinental Championship picture by challenging
Shinsuke Nakamura, whom he had defeated in an MMA fight in 2002. The Gracies' win streak continued on May 3 at
Wrestling Dontaku 2014, where they defeated Nakamura and Sakuraba. This led to Daniel's first singles match on May 25 at
Back to the Yokohama Arena, where he unsuccessfully challenged Nakamura for the IWGP Intercontinental Championship. ==Personal life==
