Best of the Super Juniors
Omega returned to NJPW in May 2013 to take part in the 2013 Best of the Super Juniors, where he managed to win five out of his eight round-robin matches, advancing to the semifinals of the tournament. On June 9, Omega was defeated in his semifinal match by Devitt, following interference from Devitt's stable, Bullet Club. A year later, he took part in New Japan's 2014 Best of the Super Juniors tournament from May 30 to June 6, finishing with a record of three wins and four losses, with a loss against Taichi on the final day, which cost him a spot in the semifinals.
