Into The Fight (sometimes stylized as Into the Fight) was a recurring professional wrestling event held annually by DDT Pro-Wrestling (DDT) around February. Originally held by DDT as an independent promotion from 2005 to 2020 (except for 2006), it was then held by CyberFight for three editions held as DDT-branded events in 2021, 2023 and 2024. The name "Into The Fight" was a reference to the 1998 Misia song "Into the Light," which was used as DDT's theme until 2014.
From 2005 to 2019, Into The Fight was produced by DDT Pro-Wrestling, an independent promotion founded in 1997 by Shintaro Muto and Pro Wrestling Crusaders alumni Kyohei Mikami, Kazushige Nosawa and Sanshiro Takagi. In 2020, DDT and its subsidiaries merged with Pro Wrestling Noah into a new company called CyberFight owned by the digital advertising company CyberAgent, with DDT and Noah persisting as separate brands under the CyberFight umbrella. Into The Fight was then held in 2021, 2023 and 2024 as a DDT-branded event.
