The event took place on April 10, 2016, in Tokyo at Ryōgoku Kokugikan, and featured nine matches, six of which were contested for championships. The main event saw the winner of the 2016 New Japan Cup, Tetsuya Naito defeat Kazuchika Okada for the IWGP Heavyweight Championship. The event aired worldwide on New Japan Pro Wrestling World and featured English commentary, provided by Kevin Kelly and Steve Corino. In addition, the event also aired in Japan as a PPV through SKY PerfecTV!. Invasion Attack 2016 was the fourth and last event under the Invasion Attack name, before the event was renamed Sakura Genesis in 2017.

Invasion Attack 2016 featured nine 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.

On February 22, 2016, NJPW announced the 2016 New Japan Cup, stating that the winner of the tournament would get to choose whether to challenge for the IWGP Heavyweight Championship (held by Kazuchika Okada), the IWGP Intercontinental Championship (held by Kenny Omega) or the NEVER Openweight Championship (held by Katsuyori Shibata) at Invasion Attack 2016. On March 12, Tetsuya Naito won the tournament, defeating Hirooki Goto in the finals, and afterwards announced he was challenging Okada for his title. Though he initially stated that he would not cash in his shot at Invasion Attack 2016, Naito changed his mind after a request from Okada. The match was officially confirmed by NJPW two days later. In an interview following his New Japan Cup win, Naito stated that his true opponent at Invasion Attack 2016 was not Okada, but NJPW owner Takaaki Kidani and booker Gedo. This would mark Naito's first shot at the IWGP Heavyweight Championship since Wrestle Kingdom 8 in Tokyo Dome in January 2014, where he unsuccessfully challenged Okada for the title. Prior to Invasion Attack 2016, Okada and Naito had faced off in six singles match with both having won three of them. The match marked Okada's fourth title defense and a chance for Naito to win the IWGP Heavyweight Championship for the first time.
