Takeru Segawa
Takeru Segawa (born July 29, 1991) is a Japanese professional kickboxer renowned for his explosive punching power, aggressive forward pressure, and historic dominance in the sport. Competing primarily in lighter weight classes, he is the only fighter in K-1 history to capture world championships in three divisions: super bantamweight (55 kg), featherweight (60 kg), and super featherweight (65 kg), achieving an unbeaten seven-year run from 2014 to 2021 that included 24 knockouts among his victories.[1][2][3] Segawa, nicknamed the "Natural Born Crusher," hails from Yonago City in Tottori Prefecture, where he grew up with two sisters and discovered martial arts through karate in elementary school, inspired by K-1 events on television. After being expelled from high school, he fully committed to kickboxing, training extensively in Thailand to master Muay Thai techniques alongside his boxing base. His professional career took off in K-1, where he defended his titles against elite opponents and became a fan favorite for his relentless style, amassing a pre-ONE record of 41 wins and 3 losses.[4][2] In April 2023, Segawa signed an exclusive multi-fight deal with ONE Championship, transitioning to their flyweight (61.2 kg) kickboxing division at age 31. His ONE debut resulted in a unanimous decision loss to Superlek Kiatmoo9 in January 2024, followed by a second-round knockout victory over Thant Zin in September 2024 and a first-round knockout loss to Rodtang Jitmuangnon in March 2025. Beyond the ring, Segawa has emerged as a philanthropist, donating to disaster relief in Myanmar, supporting childcare facilities in Japan, and funding school improvements in Vietnam and Laos, earning him the 2025 Victoria Lee Award from ONE Championship for his community efforts across Asia.[1][5][4]Early Life and Background
Childhood and Family
Takeru Segawa was born on July 29, 1991, in Yonago City, Tottori Prefecture, Japan. He grew up in a close-knit family consisting of his parents and two sisters—one older and one younger—in a serene environment surrounded by mountains, lakes, and the Sea of Japan. His father, an avid amateur historian, named him after the legendary warrior Yamato Takeru, reflecting a cultural appreciation passed down in the household. The family shared simple joys, such as watching professional wrestling on television together, which first ignited Takeru's fascination with combat sports.[4][6][7] During his early years, Segawa enjoyed outdoor hobbies like playing in rivers and exploring the nearby mountains, balancing an active lifestyle with family-oriented routines. His mother played a pivotal role in shaping his character through strict guidance, emphasizing self-reliance by teaching him that personal goals required independent effort, such as handling chores or pursuing interests without external aid. This parental influence, combined with the modest family setting, instilled a sense of discipline amid everyday challenges, though resources were limited for extracurricular pursuits beyond local activities. Despite these constraints, family bonds provided emotional support, with his sisters contributing to a supportive home dynamic.[7] In terms of early education, Segawa attended local schools where he displayed a gentle side, initially aspiring to become a childcare worker due to his affinity for children. He enrolled in high school specifically to gain qualifications in that field, but his academic path took a difficult turn. Influenced by a troublesome group of friends, he engaged in disruptive behavior, leading to his expulsion after only three months—a significant challenge that tested family resilience. His parents, particularly his mother, encouraged him to find direction independently, highlighting the hurdles of his youth while underscoring the motivational role of familial expectations. This period of upheaval ultimately steered him toward martial arts training as a teenager.[7][4]Introduction to Martial Arts
Takeru Segawa's fascination with combat sports began in his childhood in Yonago City, Tottori Prefecture, where he discovered kickboxing through watching K-1 events on television.[7] Enthralled by the dynamic striking exchanges and the prominence of karate-influenced fighters in the promotion, he developed an early dream of becoming a professional kickboxer.[8] This exposure ignited his passion, particularly after seeing icons like Andy Hug compete, whose performances highlighted the blend of power and precision that would later define Segawa's own style.[9] With no kickboxing gyms available in his local area, Segawa initiated his martial arts training with karate during the second grade of elementary school, at approximately age eight.[7] At a nearby dojo, his first coaches emphasized foundational techniques, including proper stances, basic punches like jabs and straights, and linear kicks rooted in karate traditions. His initial regimen involved repetitive drills for technique refinement, agility exercises, and light sparring to instill discipline and body control, laying the groundwork for his future specialization in kickboxing.[2] Segawa's motivations deepened amid personal challenges during adolescence, including expulsion from high school due to associations with troublesome peers and involvement in altercations, which left him seeking a constructive outlet.[2] After high school, he relocated to Tokyo and entered a kickboxing gym for the first time, where the environment reinforced his childhood aspirations and provided a path to professional pursuit.[10] This shift was driven by a desire to escape hardship, regain confidence through achievement, and turn martial arts into a viable career, as he later reflected that he "had no option but to succeed" in the sport.[7]Amateur Career
Key Tournaments
Segawa's amateur kickboxing career gained momentum during his high school years, where he transitioned from karate and began competing in various Japanese amateur tournaments starting in 2007. He participated in regional-level events across 2007-2010, securing multiple victories that highlighted his aggressive striking style and rapid progression in the featherweight division.[11] A key aspect of his development involved intensive training camps, including a self-funded solo trip to Thailand after his expulsion from high school to immerse himself in Muay Thai environments, where he engaged in amateur bouts to build resilience and technical proficiency. This period also emphasized strict weight management, as Segawa maintained discipline to compete effectively in lower weight classes despite his compact frame.[2] By 2010, Segawa had dominated the amateur scene with an overall record of 8 wins, 1 loss, and 1 draw since his debut in 2007, culminating in standout performances that positioned him for a professional transition. Notable bouts included unanimous decision wins against regional opponents, showcasing his ability to control fights through volume punching and leg kicks.[12]Notable Achievements
This strong performance showcased his potential as a rising star in Japan's martial arts community, highlighting his technical proficiency and competitive edge from an early age.[4] Among his key accomplishments, Segawa captured multiple amateur titles in the Shin Karate series, including the 114th and 115th K-2 Tournaments in the lightweight division in 2010, the 116th K-2 Tournament in lightweight in 2011, and a runner-up finish in the 22nd All Japan Shin Karate Tournament lightweight division in 2011. He also participated in the 2009 K-1 Koshien, advancing to the second round before losing. These victories demonstrated his ability to excel in high-stakes environments, blending speed, power, and strategic footwork.[2] The culmination of these amateur successes directly facilitated Segawa's transition to professionalism, culminating in a contract signing with the Krush promotion and professional debut in 2011. This opportunity allowed him to compete against seasoned fighters, building on the foundation established through his undefeated streaks and title wins in the amateur ranks.[2]Professional Career in Japan

Following his success in the super bantamweight division, Segawa moved up to the featherweight class (57.5 kg) in K-1, where he captured the 2016 K-1 World GP Featherweight Championship Tournament title.[27] In the tournament held on November 3, 2016, at Yoyogi National Gymnasium in Tokyo, Segawa advanced by defeating Jamie Whelan via unanimous decision in the quarterfinals, knocking out Qi Yun in the second round of the semifinals, and securing a unanimous decision victory over Kaito Ozawa in the final to claim the vacant championship.[28] He made one successful title defense on September 18, 2017, against Wang Junguang at K-1 World GP 2017 in Saitama, winning by unanimous decision after three rounds of pressure fighting and effective combinations.[16] Segawa vacated the featherweight title in early 2018 to pursue opportunities in the higher super featherweight division (60 kg).[1] Segawa transitioned to super featherweight in 2018 and immediately won the K-1 World GP Super Featherweight Championship Tournament at K'FESTA.1 on March 21, 2018, in Saitama.[29] He progressed through the bracket with a knockout victory over Masanobu Goshu in the semifinals and a third-round technical knockout over Kosuke Komiyama in the final, earning him the inaugural title in the class and marking his second K-1 Grand Prix victory.[30] Segawa defended the belt multiple times, starting with a unanimous decision over Kouzi on December 8, 2018, at K-1 World GP 2018 in Osaka, where he outlanded his opponent in a high-volume striking exchange over three rounds.[31] Subsequent defenses included a second-round knockout of Yodkitsada Yuthachonburi on March 10, 2019, at K'FESTA.2 via a devastating combination that dropped the Thai fighter.[32] In 2019, Segawa continued his reign with a majority decision victory over Yuta Murakoshi on November 24, 2019, at K-1 World GP 2019 in Yokohama, edging out a competitive war through superior clinch work and counters despite Murakoshi's aggressive pressure.[33] The following year, Segawa defended against Petchdam Petchyindee Academy on March 22, 2020, at K'FESTA.3, securing a second-round knockout with a right hook after weathering early leg kicks.[16] He then stopped Leona Pettas in the third round on November 3, 2020, at K-1 World GP 2020 in Fukuoka, dropping him with a left hook and finishing with ground strikes in a grueling title fight praised for its intensity.[34] Segawa's super featherweight run ended with a unanimous decision loss to Tenshin Nasukawa on June 19, 2022, at The Match 2022 in Tokyo Dome, where Nasukawa's speed and volume striking proved decisive in a highly anticipated rivalry bout.[35] Over his time in the featherweight and super featherweight divisions, Segawa amassed an impressive record, capturing titles in both classes and contributing to his status as a three-division K-1 champion.[1] His K-1 contract expired on October 31, 2022, leading to free agency and opening new opportunities beyond the promotion.[36]ONE Championship Career
Debut and Initial Matches
Takeru Segawa signed an exclusive multi-fight deal with ONE Championship on April 28, 2023, following the expiration of his contract with K-1, where he had become a free agent after vacating his super featherweight title in 2022. The move marked a significant transition for the Japanese kickboxing star, who sought to test himself against the world's top strikers in a global promotion known for its blend of kickboxing and Muay Thai influences. ONE CEO Chatri Sityodtong highlighted Segawa's 41-3 record and three-division K-1 championships as reasons for the signing, positioning him as a key addition to the flyweight division.[1] Segawa made his ONE debut on January 28, 2024, at ONE 165 in Tokyo, challenging Superlek Kiatmoo9 for the ONE Flyweight Kickboxing World Championship at 61 kg. In a high-stakes five-round bout, Segawa applied relentless pressure with combinations and body shots, nearly dropping Superlek in the third round, but the Thai champion's superior leg kicks and defensive resilience secured a unanimous decision victory (49-46, 49-46, 49-46). The fight showcased Segawa's adjustment to ONE's international stage, where he faced a shift from K-1's structured rules to a more diverse opponent pool emphasizing Muay Thai clinch work and endurance, though his aggressive style earned widespread praise for its intensity.[37][38] Following the debut loss, Segawa returned on September 27, 2024, at ONE Friday Fights 81 in Bangkok against Myanmar's Thant Zin in a non-title flyweight kickboxing bout. Trailing early after absorbing heavy strikes, Segawa mounted a dramatic comeback, landing a devastating knee to the body for a second-round knockout at 2:47, securing his first ONE victory and demonstrating resilience in the promotion's smaller-ring format. These initial outings left Segawa with a 1-1 record in his debut year, as he adapted to competing at flyweight while drawing on his K-1 super featherweight experience for tactical preparation.[4][39]Major Bouts 2023-2025
The year 2025 brought a high-stakes clash for Segawa at ONE 172 on March 23 in Saitama, Japan, where he met longtime target Rodtang Jitmuangnon in a flyweight kickboxing super-fight. Rodtang ended the bout abruptly with a devastating right punch knockout at 1:20 of the first round, dropping Segawa and marking a shocking early finish to what was anticipated as an epic rivalry encounter.[40][41] These back-to-back losses prompted Segawa to openly discuss his ongoing battles with depression and panic disorder in late October 2025, attributing some of his challenges to the pressures of elite competition while emphasizing his determination to continue fighting as a source of inspiration.[42] As of November 2025, Segawa's ONE Championship record stands at 1-2, with the defeats to top-tier strikers highlighting the steep competition level and raising questions about his trajectory at age 34. He is scheduled to return against Denis Puric in a flyweight kickboxing bout at ONE 173 on November 16, 2025, in Tokyo, a matchup that carries high stakes for redemption and potential momentum amid his recent setbacks.[43][44]Fighting Style
Technical Breakdown
Takeru Segawa is a premier stand-up striker in kickboxing, renowned for his explosive speed, precise low kicks, and fluid combinations that blend punching flurries with targeted leg strikes.[45] Standing at 168 cm with a reach of 173 cm, Segawa leverages his compact frame and proportional arm length to maintain distance control and exploit openings in closer ranges, contributing to his versatility across multiple weight classes from super bantamweight to super featherweight.[4][17] This physical profile allows him to generate rapid torque for kicks while closing distance for hand combinations without overextending, a key factor in his multi-division dominance.[46] Among his signature techniques, Segawa frequently employs devastating liver shots, often set up by feints or lead leg low kicks to draw defensive reactions before delivering a rear-leg body kick with the ball of the foot for maximum impact.[47] He also integrates high knees to the midsection during clinch entries or as counters to advancing opponents, using his explosive hip drive to target the body and sap stamina.[45] His counter-punching prowess shines in exchanges, where he absorbs pressure with a light lead foot before unleashing sharp hooks or uppercuts off the back hand, turning defensive scenarios into offensive opportunities.[46] These elements form a high-pressure system that overwhelms foes, as evidenced by brief adaptations in K-1 bouts where he adjusted low kick angles to counter taller strikers.[46] Segawa's physical conditioning emphasizes exceptional cardiovascular endurance, enabling him to sustain high-volume output—often 50-60 strikes per round—without fatigue, through rigorous daily training regimens focused on interval sparring and plyometrics.[45] His ability to cut weight effectively across divisions, from 55 kg to 65 kg classes, relies on disciplined nutrition and dehydration protocols that preserve power and speed, allowing seamless transitions between featherweight and super featherweight without compromising explosiveness.[4] Statistically, Segawa boasts a knockout rate of approximately 59% across his professional career, with 26 stoppages in 44 victories (as of November 2025), underscoring his finishing prowess in high-stakes matches.[48][49] This efficiency highlights how his technical arsenal translates to impactful results, prioritizing clean finishes over prolonged engagements.[50]Strategic Evolution
In the early stages of his career with the Krush promotion, Takeru Segawa employed an aggressive pressure-fighting approach, relentlessly advancing on opponents with high-volume combinations and lead-leg kicks to disrupt their rhythm and force exchanges.[45] This style, rooted in his karate background, emphasized forward momentum and body shots to wear down foes, as seen in his rapid ascent through Krush's lightweight divisions from 2011 onward.[7] As Segawa transitioned to K-1's super bantamweight and later super featherweight divisions, his strategy evolved toward greater incorporation of counter-striking, adapting to taller, more rangy opponents by using parries, feints, and reactive hooks to punish advances.[46] In the super featherweight class, this shift allowed him to maintain his pressure while exploiting openings, such as delivering liver-targeted roundhouses off defensive setups during title defenses against fighters like Kouzi in 2018.[45] Upon joining ONE Championship in 2023, Segawa adjusted his tactics to counter the promotion's faster pace and Muay Thai-influenced roster, incorporating clinch work and teeps to neutralize aggressive clinch specialists like Rodtang Jitmuangnon.[51] Following his debut loss to Superlek Kiatmoo9, he refined this evolution by enhancing his conditioning for sustained output, aiming for knockouts through improved footwork and distance management in flyweight bouts.[51] Key losses, particularly his 2022 unanimous decision defeat to Tenshin Nasukawa, prompted Segawa to bolster his defensive framework, focusing on better head movement and selective engagements to avoid overcommitting in high-stakes exchanges.[52] This post-loss refinement emphasized a more measured aggression, integrating evasive counters to complement his pressure base. Segawa's strategic growth has been shaped by coaching at Team Vasileus in Tokyo since 2011, where head trainer influences emphasized technical precision, evolving into international camps by 2020—including Muay Thai sessions in Thailand and sparring at Boxing Works in California—to adapt to diverse styles through 2025.[53][7]Championships and Accomplishments
