The event is scheduled to take place at the Saitama Super Arena with a heavyweight main event matchup between Josh 'The Warmaster' Barnett and Roy 'Big Country' Nelson.
There will also be an Ultimate Fighter-like reality show titled 'Road to the UFC: Japan' which will see Nelson and Barnett coaching competing teams that will feature 8 hotly tipped Japanese fighters.
The last time the 37-year-old Barnett fought in a UFC octagon was in December 2013's UFC168.
Since then Barnett has occupied his time competing in Metamoris and trying to launch his acting career outside of MMA.
Nelson has had two consecutive losses to Mark Hunt and more recently Alistair Overeem at UFC 185.
But Nelson is one of those fighters that has the ability to knock an opponent out with one punch making him very popular among fans.
Fox Sports 1 will be airing the card in September.
