Kawajiri is aware that home advantage favours Siver but believes his experience will be the key to him winning the bout.
"I know I am fighting on enemy territory," he told UFC.com's Ralph Welch.
"But MMA is a battle with many alternatives. Strategy is important. My experience will be a big advantage. I can choose my tactics in a level-headed manner.
“During the fight, even when I am in danger I can rely on my experience too," he added.
Kawajiri is very experienced having over 40 fights as a professional and admits to thinking about retiring.
"I think about retirement every fight," he said.
"I am 37 years old and I have been injured, I have been sidelined. As I get older it takes longer for my body to recover from the fatigue of training. But I just can't give up yet."
The 36-year-old Siver is also a veteran, having fought 33 times with 22 wins in his career so far.
