NTV G+ Cup Junior Heavyweight Tag League
On May 2, 2013, Pro Wrestling Noah held a press conference, officially announcing that Harada had signed with the promotion. Harada wrestled his first match under a Noah contract on May 12, when he was defeated by former tag team partner Atsushi Kotoge in a singles match. Harada picked up his first win under a Noah contract on May 18, when he defeated rookie Hitoshi Kumano. Harada then hand-picked Kumano as his partner for the 2013 NTV G+ Cup Junior Heavyweight Tag League, which was contested for the vacant GHC Junior Heavyweight Tag Team Championship and took place between July 11 and 28. Despite eyeing a match with Atsushi Kotoge and Taiji Ishimori in the finals, Harada and Kumano ended up losing all four of their matches, failing to advance from their block. On August 24, Harada gained a measure of revenge on Kotoge by pinning him in a tag team match, where he and Kumano faced Kotoge and Ishimori. Later in the event, Harada and Kumano nominated themselves as the next challengers for the GHC Junior Heavyweight Tag Team Championship. On September 7, Harada picked up a major singles win over one half of the reigning champions, NJPW representative Jyushin Thunder Liger. However, on September 16, Harada and Kumano failed to capture the GHC Junior Heavyweight Tag Team Championship from Liger and Tiger Mask. On October 19, Harada pinned GHC Junior Heavyweight Champion Taiji Ishimori in a six-man tag team match, after which he was named the next challenger for his title. Harada received his title shot on November 2, but was defeated by Ishimori. On December 31, Harada made a one-night return to Osaka Pro, teaming with Takoyakida and Ultimate Spider Jr. in a six-man tag team main event, where they defeated Bad Stream (Kazuaki Mihara, Quiet Storm and Tadasuke). On January 3, 2014, Harada returned to NJPW, teaming with Hitoshi Kumano in a tag team match, where they were defeated by Jyushin Thunder Liger and Super Strong Machine.
