 Passage 2:In 2010 Richards was invited to take part in New Japan Pro Wrestling's Best of the Super Juniors tournament along with fellow North American and ROH wrestler, Kenny Omega. Richards entered the two-week-long tournament on May 30, but although he managed to win five out of his seven matches, he finished third in his block and narrowly missed advancing to the semifinals of the tournament. After the tournament Richards began working regularly for New Japan Pro Wrestling, joining the promotion's top heel stable Chaos, and no longer made appearances for Pro Wrestling Noah. In November 2010 Richards and Rocky Romero, reviving the No Remorse Corps name, made it to the finals of a five-day-long Super J Tag League tournament, before being defeated by their Chaos team mates Jado and Gedo. On December 11, 2010, Richards received a shot at the IWGP Junior Heavyweight Championship, but was defeated by the defending champion, Prince Devitt.
