Four Fights in Three Countries, and One Tokyo Sunday That Carries the Week
The fight week opens in Osaka on Wednesday, when Sebastian Reyes meets Kyonosuke Kameda, and it closes in Nonthaburi on Friday with Srisaket Sor Rungvisai still waiting on an opponent. In between, Sunday in Tokyo carries both the week's world title and its best fight. Takuma Inoue defends the WBC bantamweight title against Tenshin Nasukawa at the Toyota Arena, and underneath them, Sam Goodman and Ryosuke Nishida box for a vacant interim title, with a fight against Takuma's own brother waiting for the winner. Both corners are in the fight pool in each of Sunday's bouts, which happens twice in one afternoon only rarely.
Takuma Inoue vs Tenshin Nasukawa: A Rematch for the WBC Bantamweight Title
Inoue won the first fight on all three scorecards last November, ending a run that had covered fifty-three professional fights across two sports. Nasukawa took the early rounds before Inoue's length and jab closed the second half down. Each has fought once since. Inoue dropped Kazuto Ioka twice at the Tokyo Dome in May, winning 120-106, 119-107 and 118-108, and Nasukawa wore Juan Francisco Estrada down and stopped him after nine rounds in April, a result that stood as a WBC final eliminator.
Nasukawa's first title challenge came in his eighth professional fight, and nine rounds against a fifty-fight former titleholder is the deepest water he has been in. Inoue has twenty-four fights behind him and has been the longer, straighter puncher in every round the two have shared. Inoue has five knockouts in twenty-four fights and Nasukawa three in nine, and Inoue has said he intends to stop him this time. The belt is the prize, in front of a Tokyo crowd, on Prime Video in Japan and DAZN elsewhere, with Goodman and Nishida in support.
Sam Goodman vs Ryosuke Nishida: The Winner Fights Naoya Inoue
Goodman was twice booked to fight Naoya Inoue and twice withdrew with eyelid cuts from sparring, in December 2024 and again in January 2025. He moved up to challenge Nick Ball for the WBA featherweight title in Riyadh in August 2025 and lost a decision, the only defeat in his twenty-three fights. Two wins followed, the second a twelve-round decision over Rodrigo Fabian Ruiz in Wollongong in April that restored his IBF mandatory position. Nishida held the IBF bantamweight title from May 2024 until Junto Nakatani forced him to retire on his stool after six rounds with a damaged eye, and he has boxed once since, a technical decision over Bryan Mercado in Osaka in February.
Goodman is an orthodox volume boxer with eight stoppages in twenty-three fights. Nishida is a southpaw with two in twelve who has taken Emmanuel Rodriguez, Christian Medina and Daigo Higa the full distance. Both build a lead out of small accumulated advantages rather than one big moment. Nishida is stepping up from bantamweight for the first time, and Muto Promotions won the purse bid at $610,000, which is why the fight sits in Tokyo rather than Sydney or Manila.
The vacant interim IBF junior featherweight title makes the winner next in line for Naoya Inoue, Takuma's younger brother, undisputed at 122 pounds and fresh off a decision over the same Nakatani in front of 55,000 people at the Tokyo Dome in May. Goodman has been waiting on that fight since 2024. Nishida has not fought for a title since Nakatani closed his eye. Two twelve-round technicians are fighting for the right to challenge the best fighter in the sport, on a night whose main event is the bigger draw and, on paper, the more even fight.
Sebastian Reyes vs Kyonosuke Kameda: Osaka Ahead of Either of Them
Reyes, who fights under his paternal name Hernandez, has one loss in twenty-two fights, a twelve-round decision to Junto Nakatani in Riyadh last December that two of the three judges scored 115-113. He returned in August with a second-round stoppage of Jose Lopez in Metepec, his nineteenth knockout. Kameda outpointed John Riel Casimero over ten rounds in Bishkek last October, a result that followed a seventh-round stoppage loss to Luis Nery in Tijuana and a majority-decision loss to Alan David Picasso in Las Vegas.
Kameda stands five foot nine with a seventy-inch reach and still fights going forward, working body hooks and overhand rights on the inside. Hernandez throws in volume and concedes no ground. Kameda has faded in his longer fights before, and Nery found his chin inside seven rounds. The contract is eight rounds at 126 pounds with no title attached. Hernandez is twenty-five and using the trip to rebuild toward another run at 122. Kameda's last three fights were in Mexico, Nevada and Kyrgyzstan, and this one is in the city he was born in.
Srisaket Sor Rungvisai: A Fight Still Missing an Opponent
Rungvisai twice held the WBC junior bantamweight title, both times by beating Roman Gonzalez, and his last confirmed appearance was a six-round points win over Wuttichai Yurachai in Bangkok. He is scheduled for eight rounds in Nonthaburi on Friday, moving up to bantamweight, and as of this week the fight still carries no announced opponent. A result this small would not move a stable either way, and an unconfirmed one cannot yet be written about at all beyond that it is on the calendar.
The Bigger Picture
Junto Nakatani sits behind three of this week's four storylines without boxing once in the window. He beat Hernandez by decision in December, forced Nishida to retire on his stool in the fight that cost him the IBF bantamweight title, and then moved up and lost the undisputed decision to Naoya Inoue in May that put a stop to both of those results. Everyone Nakatani has touched this year is either fighting to rebuild from it or fighting for a shot at the man who beat him. Nasukawa is the one name in the group who has not shared a ring with Nakatani, and Sunday is his chance to put a second Inoue on the list before either.
Bantamweight and the weight above it have not been this busy in one week all season. A world title changes hands or stays put in Tokyo, a vacant interim belt sets up a fight with the sport's best fighter, and two more results in Osaka and Nonthaburi round out a week that started thin and ended with four separate storylines running at once.
Promoter League: Four Signings on One Sunday in Tokyo
Every fighter in both Tokyo bouts is on the Promoter League price list, so a promoter can have four signings in the ring on the same Sunday. Nasukawa is the most expensive of the four at $6M, and Inoue, Goodman and Nishida cost $4.5M each, putting all four inside $19.5M of a $100M purse. Three of a promoter's fighters on one night earns +3 and four earns +5, on top of whatever the results earn, and holding both corners of a bout guarantees one win. The winner of the rematch also takes +3 for a world-title win.
Goodman against Nishida is currently flagged as a Split Decision, with the Split sitting at 46 to 54, inside the 40 to 60 band, and every promoter holding the winner takes an extra +5 if it is still there when the bout locks. Inoue and Nasukawa sit at 36 to 64, outside the band. Fighters lock at midnight UTC on fight day, which is 9am Sunday in Tokyo and 10am in Sydney, so the window to sign closes hours before the first bell. Reyes is on the list at $2.5M and locked already, since his fight in Osaka falls earlier in the week, and Rungvisai carries a price but no next fight date, so he is not signable off this week's action either way.
Verdict
Inoue against Nasukawa is the main event and Inoue's fight to lose if the second half goes the way the first fight did. Goodman against Nishida is the harder fight to read, two technicians who both win on volume rather than one moment, fighting for a shot at the best fighter either has ever shared a division with. Hernandez should have too much for Kameda if Osaka goes to form, and Rungvisai's fight is not yet a fight anybody can weigh up.
A week that opened with one thin storyline in Osaka closes with a world title, a title-shot eliminator and Naoya Inoue's name hanging over both. Whoever is still standing on Sunday night in Tokyo carries the week, and it is the only building where that was ever going to be decided.
