Two Korean fighters will face Japanese opposition at Lumpinee Stadium on August 28, with Son competing at ONE Friday Fights 168 and Jung making his promotional debut at The Inner Circle 28.
South Korea will have two representatives competing under the ONE Championship banner when Geun Ho Son and Jung Hyun Woo enter Bangkok’s iconic Lumpinee Stadium on Friday, August 28.
The Korean fighters will appear in separate events during ONE Championship’s doubleheader. Jung meets Keisuke Monguchi in a strawweight kickboxing contest at The Inner Circle 28, while Son faces Ryoto Nishiyama in a three-round flyweight MMA bout at ONE Friday Fights 168.
Both contests also carry a Korea-versus-Japan dimension, giving Korean combat-sports fans two compelling reasons to follow the action from Bangkok.
Geun Ho Son Brings a Three-Fight Winning Streak to ONE
Representing Korea Top Team, Geun Ho Son arrives at ONE Friday Fights 168 with three consecutive victories and growing momentum on the Korean MMA scene.
Son most recently competed at TFC 22 on July 11, stopping Nadir Dosimbetov with ground-and-pound just 1:14 into the opening round. The dominant performance demonstrated his ability to close the distance, establish control and generate fight-ending offense once the action reached the canvas. RANK5 and MK Sports reported the first-round stoppage.
That victory followed Son’s championship success at Brawl International, where he defeated Japan’s Tsubasa Kamino by first-round ground-and-pound to capture the promotion’s vacant bantamweight belt. The title win strengthened Son’s credentials as a versatile competitor capable of operating across multiple weight classes.
His appearance at ONE Friday Fights 168 represents another significant step forward. Fighting at Lumpinee Stadium gives Son an opportunity to introduce himself to ONE’s international audience while extending a winning streak that has carried him from the Korean regional circuit to one of combat sports’ most recognizable stages.
Ryoto Nishiyama Presents a Dangerous Japanese Test
Son will not receive an easy introduction.
Ryoto Nishiyama enters the matchup on a four-fight winning streak after building experience in Japan’s DEEP promotion. He most recently stopped Yoshizumi Kobayashi by KO/TKO at 4:19 of the first round at DEEP Tokyo Impact 2026: 1st Round.
The Japanese fighter has rebounded from the two defeats at the beginning of his professional career by winning four straight, bringing his listed record to 4-2. Tapology lists all four victories as finishes, making Nishiyama a particularly dangerous opponent during the early exchanges.
That creates an intriguing stylistic battle. Son has displayed strong positional control and damaging ground-and-pound, while Nishiyama’s recent results suggest that he will be prepared to pursue a finish from the opening bell.
Their fight is scheduled as a three-round flyweight MMA contest. For Son, it is both a promotional opportunity and another chapter in his recent run against Japanese opposition.
Jung Hyun Woo Makes His ONE Championship Debut
Earlier in the doubleheader, Jung Hyun Woo will make his ONE Championship debut against Japan’s Keisuke Monguchi.
Their contest has been confirmed as a strawweight kickboxing match and will take place during The Inner Circle 28, ONE’s member-exclusive event preceding the main Friday Fights card.
Jung’s debut adds a second Korean storyline to the evening. Unlike Son, who will compete under MMA rules, Jung enters ONE’s deep striking environment—a roster and ruleset built around elite kickboxing and Muay Thai talent.
Monguchi offers an immediate international test. The Japanese striker will share the Lumpinee ring with Jung as both men attempt to establish themselves in ONE’s strawweight kickboxing division.
For Jung, the fight is an opportunity to make an immediate impression following his recent signing. A successful debut at Lumpinee could position him for further appearances against ONE’s international striking roster.
Two Korea-Japan Matchups at Lumpinee Stadium
The presence of Son and Jung gives the August 28 doubleheader a distinct Korean angle.
Son will attempt to halt Nishiyama’s four-fight finishing streak in MMA. Jung, meanwhile, will test his striking against Monguchi in kickboxing. Although the contests take place under different rules, both feature Korean fighters seeking to advance their careers against Japanese opposition.
The bouts also reflect the different pathways available through ONE Championship’s Bangkok events. ONE Friday Fights has developed into an international platform for emerging fighters across MMA, Muay Thai and kickboxing, while The Inner Circle provides additional opportunities for developing talent in an exclusive event format.
For Korean combat sports, August 28 offers a chance to evaluate two fighters at different stages of their ONE journeys: Son arrives with regional championship experience and a three-fight winning streak, while Jung begins a new chapter with his promotional debut.
