The 36 year old Sakamoto had stated the bout would be his final contest and he hand selected the 26 year old Koshikawa as his opponent. Sadly for Sakamoto Koshikawa got a read on the veteran early on and looked calm and relaxed as he landed clean shots, including a nasty left mid way through round 1.
Sakamoto managed to remain on his feet but as the bout went on he seemed to be putting more and more effort into his work and took more and more heavy leather from Koshikawa, who looked so calm and relaxed. Sadly by the end of round 2 Sakamoto looked exhausted though he continued to fight on, mustering all he had to fight through rounds 3 and 4, with the 4th being particularly one-sided as Koshikawa picked up his pace.
At the end of round 4 Sakamoto was retired by his corner, saving him from further punishment and giving Koshikawa his biggest career win.
After the bout Sakamoto spoke about wanting to open a restaurant whilst Koshikawa, who showed a lot of respect to Sakamoto, suggested that he was wanting to get into the domestic title mix.
