WBO champion Paul Butler (34-2-0, 15KOs) steps in against one of the best pound-for-pound fighters in the sport in Naoya Inoue (23-0-0, 20KOs) in a bid to become the first undisputed bantamweight champion.
Tokyo’s Ariake Arena will host the event at around 12:30pm UK time as Butler looks to dethrone the Japanese star in his own backyard.
No UK broadcaster has been confirmed at the time of writing.
Butler was upgraded to full WBO champion following his April victory over Jonas Sultan after previous holder John Riel Casimero was stripped for failing to defend his title on two separate occasions.
Inoue blasted through Nonito Donaire in their rematch five months ago to add the WBC belt to his WBA and IBF titles.
The 29-year-old is dubbed ‘The Monster’ having won twelve of his last thirteen fights inside the distance and is ranked number two in the Ring Magazine’s pound-for-pound rankings.
Liverpool’s Butler enters the fight a sizeable underdog but victory in Japan would rank as one of the best victories on away soil by a British fighter in recent history.
Brother of Naoya, Takuma Inoue (16-1-0, 3KOs) returns for the second time in 2022 in a ten-round featherweight clash against the Philippines’ Jake Bornea (14-3-1, 7KOs).
Tokyo 2020 Olympian Peter McGrail (5-0-0, 4KOs) will also face Japan’s Hironori Miyake (9-12-2, 1KO) in an eight-round featherweight clash.
The Liverpudlian McGrail halted Alexander Espinoza after five rounds in October.
