Storylines
Wrestling Hinokuni 2015 featured professional wrestling matches that involved different wrestlers from pre-existing scripted feuds and storylines. Wrestlers portrayed villains, heroes, or less distinguishable characters in the scripted events that built tension and culminated in a wrestling match or series of matches.

In the first title match, NWA representative Steve Anthony successfully defended the NWA World Junior Heavyweight Championship against NJPW's Jushin Thunder Liger. This was a rematch from a match in Las Vegas earlier in the month, where Anthony also defeated Liger to capture the title. The second title match saw NJPW's Hiroyoshi Tenzan make his second successful defense of the NWA World Heavyweight Championship against NWA's Big Daddy Yum-Yum.

Several matches at the event also built to matches taking place at Wrestling Dontaku 2015 the following week. One of these matches saw Bullet Club's Doc Gallows, Karl Anderson and Kenny Omega defeat Alex Shelley, Tetsuya Naito and Tomoaki Honma in a six-man tag team match in the buildup to an IWGP Junior Heavyweight Championship match between champion Omega and challenger Shelley.

Another match built to the main event of Wrestling Dontaku 2015, which would see Hirooki Goto challenge Shinsuke Nakamura for the IWGP Intercontinental Championship. At Wrestling Hinokuni 2015, Nakamura, Kazushi Sakuraba and Toru Yano defeated Goto, Hiroshi Tanahashi and Katsuyori Shibata. In the main event of the show, Tomohiro Ishii defended the NEVER Openweight Championship against Togi Makabe. This was a rematch from January's Wrestle Kingdom 9 in Tokyo Dome, where Makabe defeated Ishii to become the new NEVER Openweight Champion. However, on February 14, Makabe was stripped of the title after he was forced to pull out of a scheduled rematch with Ishii due to influenza, which led to Ishii defeating Tomoaki Honma to recapture the now vacant title.
