Background
On November 25, 2009, a press conference was held to announce co-promotion between DREAM and Sengoku for Dynamite!! 2009.[4] Currently, there are plans for seven different "DREAM vs. Sengoku" fights on the card.[5] The planned bout between Hidehiko Yoshida and Satoshi Ishii was officially moved from Sengoku's New Year's Eve show to Dynamite!! 2009.[6] On December 22, 2009, it was announced that DREAM Lightweight champion Shinya Aoki would not be taking on fellow DREAM fighter Tatsuya Kawajiri in a challenge for the title belt, but instead would be fighting Lightweight Champion, Mizuto Hirota to fit the DREAM vs Sengoku card, but was not a unification bout.
Masato was originally intended to face Giorgio Petrosyan, the 2009 MAX Champion, but Petrosyan fractured a bone in his right hand during his semi-final bout versus Yuya Yamamoto.[7] The fight was billed as Masato's retirement fight.
Hideo Tokoro was scheduled to face Marlon Sandro, but Sandro pulled out on short notice due to an injury. Jong Man Kim filled in for Sandro against Tokoro.[8]
Note: Bob Sapp was brought back into the tournament replacing Gegard Mousasi due to injury.
