On July 18, 2015, NJPW held a press conference on various items relating to the future of the promotion. One of these was the establishment of a developmental branch, where NJPW could discover and develop both Japanese and foreign wrestlers. It was also intended as a place where trials could be held for outside wrestlers and where injured wrestlers could go to get back in shape. The plan was for the branch to eventually start running its own small shows. The project quickly drew comparisons to WWE's NXT developmental branch. NJPW had earlier attempted a developmental branch with a project named NEVER, which held shows between 2010 and 2012. Recently, NJPW had been described as "lax in cultivation of new talent", however, on January 3, 2016, the promotion introduced four new wrestlers with Hirai Kawato and Teruaki Kanemitsu wrestling their debut matches, while Katsuya Kitamura and Tomoyuki Oka were announced as the two newest recruits to the NJPW dojo. Dave Meltzer called the recruitment of the two former top amateur wrestlers "robably the biggest move in a couple of years when it comes to new talent". The same day, NJPW announced that their developmental branch Lion's Gate would be holding its first show on February 25, 2016, in Tokyo's Shinjuku Face.
