Sakura Genesis is an annual professional wrestling event promoted by New Japan Pro-Wrestling (NJPW) since 2013. Held annually at Tokyo's Ryōgoku Kokugikan, the event has been nicknamed "Spring Showdown at Ryōgoku" (春の両国決戦, Haru no Ryōgoku Kessen). Originally known as Invasion Attack, the event was renamed in 2017 after the sakura, in English "cherry blossom", which blooms in early April. The event is followed by the New Japan Cup, with the main event being the winner of the New Japan Cup against the champion of their choice, usually being the IWGP Heavyweight Champion. The event was not held in 2019, the NJPW-Ring of Honor co-produced G1 Supercard event was held instead. The event was originally scheduled to take place in 2020 on March 31, but was cancelled due to the COVID-19 pandemic.
