Venue: Korakuen Hall, Tokyo, Japan
10-round non-title bout – Super Bantamweight (126 lbs / 57 kg limit)
Fighter Records and Background
Marlon “The Nightmare” Tapales (Philippines, 41-4, 22 KOs, southpaw, age 34) is a former unified super bantamweight world champion (WBA/IBF) and two-division titleholder. He remains world-ranked and is on a mission to reclaim a belt after a 10th-round KO loss to Naoya Inoue in 2023. Tapales is the clear favorite and brings elite power, southpaw awkwardness, and proven experience against top international opposition.
Yukinori Oguni (Japan, 23-4-3, 9 KOs, age 37) is a former IBF super bantamweight champion (won the title in 2016). The local hero is a durable warrior with solid boxing fundamentals but has been inconsistent in recent years and is coming off several stoppage losses to power punchers. He fights at home in Tokyo, which may provide crowd support and familiarity with the ring.
Recent Form
Tapales (last 5 fights: 4-1, 2 KOs):
Oct. 29, 2025 – KO 6 Fernando Toro (rebuilt momentum with body work)
Apr. 27, 2025 – RTD 3 Jon Jon Jet (won WBC International Silver super bantamweight title)
Sep. 7, 2024 – UD 10 Saurabh Kumar
May 10, 2024 – KO 1 Nattapong Jankaew
Tapales has looked sharp and motivated in his comeback fights, showing improved conditioning and finishing ability. He arrived in Tokyo early (March 29) and has been reported in near-peak form.
Oguni (last 5 fights: 2-2-1):
Oct. 1, 2025 – UD 8 Chainoi Worawut (bounced back with a solid win)
May 20, 2025 – TKO 6 Subaru Murata (lost WBO Asia Pacific title bid)
Apr. 10, 2025 – TKO 1 Jon Jon Estrada
Oct. 13, 2024 – TKO 1 Filipus Nghitumbwa
Oguni has shown flashes but has been vulnerable to early stoppages against aggressive punchers. His recent activity is decent for a 37-year-old, but durability questions persist.
Injury Report
No reported injuries for either fighter. Tapales has trained without setbacks and is described as fully healthy and in peak condition for this tune-up bout. Oguni has no disclosed issues and is expected to be at full strength for his home appearance. Both are cleared and ready to go.
Fighter Matchups / Styles
Southpaw vs. Orthodox: Tapales’ left-handed stance will be a major factor. Oguni has faced southpaws before but has been hit cleanly by power punchers in recent losses.
Power & Finishing: Tapales (47% KO rate) possesses legitimate one-punch power and body-attack prowess. Oguni (39% KO rate) relies more on volume and durability but has been stopped in three of his last four defeats.
Experience & Age: Tapales is younger (34 vs. 37), more active, and has faced a higher level of competition (including a win over Murodjon Akhmadaliev). Oguni’s best days were nearly a decade ago.
Home Advantage: Oguni will have the Korakuen Hall crowd behind him, which could influence close rounds, but the Filipino southpaw’s pressure and power should neutralize the atmosphere.
Tapales holds clear edges in speed, power, and recent form. Expect him to control the distance early and look to break Oguni down in the mid-to-late rounds.
