Seo Hee Ham
Ham Seo-hee (born March 8, 1987), professionally known as Seo Hee Ham, is a South Korean mixed martial artist and kickboxer competing primarily in the atomweight and strawweight divisions.[1][2] Hailing from Gangwon Province and training out of Busan with Team MAD, she stands at 5 feet 2 inches (158 cm) tall with a 62-inch reach and fights in a southpaw stance.[1][3] Her professional MMA record stands at 26 wins and 9 losses, with a majority of victories coming by decision (19), alongside 4 knockouts and 3 submissions.[4] Ham began her martial arts journey at age 17, initially training in taekwondo and kickboxing after interests in piano and performing arts, including acting roles in South Korean television shows.[2] She made her professional MMA debut in 2007, defeating an opponent with significantly more experience via first-round TKO, and quickly rose through regional promotions.[2][4] Among her most notable achievements are multiple championship wins: the Jewels Atomweight Championship, Road FC Women's Atomweight Championship, and RIZIN Women's Super Atomweight Championship, which she captured via split decision over Ayaka Hamasaki on December 31, 2019.[2][5] In major international leagues, she competed in the UFC from 2014 to 2016, posting a 1-3 record with her lone win being a unanimous decision over Cortney Casey.[3] Transitioning to ONE Championship in 2021, Ham secured victories over Denice Zamboanga (twice, including a split decision) and Itsuki Hirata before challenging for the ONE Women's Atomweight Interim World Championship in a third-round TKO loss to Stamp Fairtex on September 29, 2023.[2] Following over two years of inactivity, Ham announced in October 2025 that she had become a free agent, expressing enthusiasm for returning to competition in a prominent promotion.[6] Known for her versatile striking and grappling skills, she has earned nicknames like "Hamzzang" and "Hamderlei Silva" for her aggressive, powerful style reminiscent of heavyweight Wanderlei Silva.[2][1] Her career highlights her as one of South Korea's pioneering female MMA fighters, blending technical proficiency with knockout power in a sport dominated by endurance-based decisions.[2]Early life and background
Childhood and family
Seo Hee Ham was born on March 8, 1987, in Gangwon Province, South Korea.[1][7] From a young age, Ham displayed a passion for the performing arts, dreaming of becoming a stage performer and singer while nurturing an interest in the piano.[8][9] Her parents initially supported these aspirations, allowing her to attend a performing arts academy. In fifth grade, around 2000, she passed an audition for a talent agency and began working as a child TV actor, appearing in a children's drama as well as several other TV dramas and a stage play.[9][8] Ham's family life was marked by close sibling bonds and parental guidance amid challenges. She has a sister who provided crucial support during her formative years. However, her acting pursuits were disrupted by frequent school conflicts, where Ham often defended friends, leading to multiple school changes and her mother's decision to tear up her acting certificates in disapproval. This parental intervention, stemming from concerns over her involvement in scuffles, ultimately forced Ham to pivot away from the entertainment industry.[9][8]Entry into combat sports
After pursuing a career in acting during her childhood, Seo Hee Ham began her martial arts training at the age of 17 in 2004, motivated by a desire to join the military voluntarily in South Korea.[2] She initially focused on taekwondo at a local gym in Busan, drawn to the discipline for its emphasis on self-defense and physical conditioning.[10] Ham soon discovered that the same gym offered kickboxing classes, which she incorporated into her routine to complement her taekwondo practice. Over time, she developed a preference for full-contact striking styles such as kickboxing and Muay Thai, finding them more engaging than the point-based scoring of taekwondo due to their intensity and direct physical challenges.[10] In 2010, Ham joined Busan Team MAD, a prominent gym specializing in kickboxing and MMA, where she began MMA training alongside male athletes as female-specific programs were scarce at the time.[9] This environment accelerated her development, exposing her to rigorous sparring and competitive drills that honed her foundational striking skills. Through early amateur competitions in regional kickboxing events, she gained practical experience, securing several titles that built her confidence in full-contact scenarios.[7][2]Mixed martial arts career
Career beginnings in Japan
Seo Hee Ham launched her professional MMA career in Japan with a stunning debut on February 16, 2007, at Deep 28th Impact, defeating seasoned champion Hisae Watanabe by unanimous decision over two rounds in front of 2,427 spectators. This victory immediately drew attention to the 23-year-old South Korean fighter, who had transitioned from kickboxing and showcased sharp striking early on. Her follow-up bout on May 12, 2007, at Deep's ClubDeep Toyama event ended in a second-round submission loss to Miku Matsumoto via triangle choke, highlighting the grappling challenges she would need to address in the Japanese scene.[5][8] Ham soon transitioned to the prominent Smackgirl promotion, securing a unanimous decision win over Ayumi Saito on September 5, 2007, at Smackgirl: Queens' Hottest Summer. She followed with a unanimous decision loss to undefeated Yuka Tsuji on December 25, 2007, at Smackgirl: Starting Over, but rebounded with another decision victory against Saori Ishioka on February 13, 2008, at Smackgirl: World ReMix 2008 Opening Round. Her Smackgirl run concluded with a first-round armbar submission defeat to the elite Megumi Fujii on April 24, 2008, at Smackgirl: World ReMix 2008 Second Round, an experience that tested her limits against Japan's top grapplers. These bouts, against highly experienced opponents, helped forge her reputation as a resilient striker while exposing vulnerabilities in submissions.[5][4] After a year-long hiatus amid limited opportunities following Smackgirl's closure, Ham debuted in the Jewels promotion on September 12, 2009, earning a unanimous decision over Misaki Takimoto at Jewels: Fifth Ring. She built momentum with additional decision wins, including against Mai Ichii on July 30, 2010, at Jewels: Ninth Ring, and a split decision over Mika Nagano on December 16, 2010, at Jewels: 11th Ring during a tournament semifinal. However, she fell short in the tournament final that same night, losing a unanimous decision to Ayaka Hamasaki. Ham continued in Jewels with a unanimous decision victory over Mei Yamaguchi on July 8, 2011, at Jewels: 15th Ring, but suffered a first-round TKO loss to Hamasaki via corner stoppage on December 16, 2011, at Jewels: 17th Ring. She also notched a second-round unanimous decision win over Saori Ishioka on February 24, 2011, at Deep: 52 Impact, bridging her time between promotions. These fights refined her stand-up game, leveraging her kickboxing foundation for precise combinations and distance management.[5][4] Returning after another break in 2013, Ham submitted Ryo Mizunami with an armbar in the first round on April 21, 2013, at Gladiator: Dream, Power and Hope, demonstrating improved grappling. This set up her title opportunity, where she defeated Naho Sugiyama by unanimous decision over three rounds on May 24, 2013, at Jewels: 24th Ring to claim the Jewels Atomweight Championship—her first major MMA title. She defended the belt successfully against Sadae Numata by unanimous decision on November 4, 2013, at Deep: Jewels 2, following Jewels' merger with Deep. Over this foundational period in Japanese promotions from 2007 to 2013, Ham amassed a record of 12 wins and 5 losses, evolving into a well-rounded fighter with a striking emphasis derived from her kickboxing roots, where she had competed as a professional since 2005.[5][11] As a South Korean fighter navigating Japan's male-dominated MMA landscape, Ham encountered significant challenges, including language barriers that complicated communication and contract negotiations. She adapted culturally by basing herself in Japan for extended periods, training rigorously and relying on a Korean-Japanese couple for logistical support, though this relationship later soured due to financial exploitation involving forged documents and stolen earnings estimated at around $30,000. Despite these hurdles, her frequent fights—18 of her first 19 MMA bouts occurred in Japan—fostered resilience and helped her integrate into the local scene, earning respect through consistent performances against elite competition.[8]UFC tenure
Ham signed with the Ultimate Fighting Championship in November 2014, becoming the first South Korean woman to join the promotion, shortly after defending her Deep Jewels atomweight title.[12] She made her UFC debut on December 12, 2014, at The Ultimate Fighter: A Champion Will Be Crowned Finale against Joanne Calderwood in a strawweight bout. Ham lost the fight by unanimous decision (30-27 x3) after three rounds, where she landed 58 significant strikes but absorbed 112 while defending 66% of takedown attempts.[3][4] Ham rebounded with a victory on November 28, 2015, at UFC Fight Night 79 against Cortney Casey, winning by unanimous decision (29-28 x3). In the bout, she outstruck her opponent 71 to 64 in significant strikes, maintaining a grappling-heavy approach with no successful takedowns attempted or landed.[3][4] Her UFC tenure continued with two more losses: a unanimous decision defeat to Bec Rawlings on March 19, 2016, at UFC Fight Night 85, where she landed a fight-high 92 significant strikes but was outpointed on the scorecards (29-28 x3); and a split decision loss to Danielle Taylor on November 26, 2016, at UFC Fight Night 101, landing only 31 significant strikes in a low-output affair.[3][4] Ham was released from the UFC following her 1-3 record in the promotion.[13]| Date | Event | Opponent | Result | Method | Significant Strikes Landed by Ham |

Road FC and Rizin periods
Following her release from the UFC after consecutive decision losses in 2016, Seo Hee Ham returned to the South Korean promotion Road FC in 2017, where she experienced a notable resurgence by establishing herself as the premier atomweight competitor. On June 10, 2017, at Road FC 39 in Seoul, Ham won the inaugural Road FC Women's Atomweight Championship in a main event bout against Mina Kurobe, the reigning DEEP Jewels Atomweight Champion.[5][14] Ham dominated the fight with superior striking and pressure, securing a technical knockout via punches at 4:11 of the third round.[5] This victory improved her record to 18-8 and highlighted her adaptability at the lower weight class after competing at strawweight in the UFC.[4] Ham's title reign emphasized her striking prowess and finishing ability, as she transitioned seamlessly between promotions to target regional dominance. Later that year, on December 23, 2017, at Road FC 45 in Seoul, she made her first successful defense against Jinh Yu Frey, a highly ranked Invicta FC contender known for her wrestling background.[15] Ham overwhelmed Frey with aggressive forward pressure and heavy punches, ending the fight with a knockout at 4:40 of the first round.[16] The finish was lauded for its brutality, drawing comparisons to the explosive style of former PRIDE star Wanderlei Silva and earning Ham the moniker "Hamderlei Silva."[15][17] Ham defended her Road FC title once more on December 15, 2018, at Road FC 51 against Jeong Eun Park, securing a unanimous decision victory after three rounds of controlled striking and grappling exchanges.[4][18] In 2019, Ham transitioned to Rizin Fighting Federation, where she went undefeated in three bouts. She debuted on July 28 at Rizin 17, defeating Tomo Maesawa by TKO (knees) in the first round at 3:14.[4] On October 12 at Rizin 19, she followed with a second-round TKO (punches) over Miyuu Yamamoto at 4:42.[4] Ham capped the year by capturing the Rizin Women's Super Atomweight Championship on December 31 at Rizin 20, edging out rival Ayaka Hamasaki via split decision after a competitive three-round battle.[4][5] These accomplishments in Road FC and Rizin underscored Ham's strategic choice to compete in familiar regional circuits, where she built rivalries with international talent and affirmed her status as a top Asian women's MMA fighter from 2017 to 2019.[19] Her performances featured a blend of technical striking and opportunistic finishes, contributing to her reputation for high-impact bouts in the atomweight division.[20]ONE Championship and title challenge
Ham made her ONE Championship debut on September 3, 2021, at ONE: Empower, where she edged out Denice Zamboanga via split decision in a closely contested atomweight bout that showcased her technical striking and grappling defense.[21] This victory marked the beginning of a four-fight winning streak in the promotion, solidifying her status as a top contender in the division. She rematched Zamboanga on March 25, 2022, securing a unanimous decision win at ONE x by outworking her opponent with precise combinations and effective pressure over three rounds.[5] Continuing her momentum, Ham defeated Itsuki Hirata on March 24, 2023, at ONE Fight Night 8 via unanimous decision, dominating the Japanese prospect with superior wrestling and ground control while landing cleaner strikes throughout the fight.[22] These performances, combined with her extensive resume from promotions like Road FC and Rizin, positioned her as the number one ranked atomweight contender and earned her a shot at the vacant ONE Interim Women's Atomweight World Championship.[23] On September 29, 2023, at ONE Fight Night 14, Ham challenged Stamp Fairtex for the interim title in the main event at Singapore Indoor Stadium. The fight was a high-stakes striking war, with Ham opening strong by dropping Stamp with a sharp left hand in the first round and attempting multiple takedowns to leverage her grappling expertise.[24] However, Stamp defended the ground attempts effectively and turned the tide in the third round, unleashing devastating body shots and knees that forced a TKO stoppage at 1:04, handing Ham her first loss in ONE.[25] In the aftermath of the defeat, Ham reflected on her more than 15-year professional career, expressing pride in her longevity and resilience while acknowledging the near-miss at securing ONE gold as a poignant highlight of her journey across multiple promotions.[13] The loss extended her overall record to 26-9 but underscored her status as one of Asia's premier female MMA talents, having competed at the highest levels without ever capturing a world title in the promotion.[1]Hiatus and free agency
Following her unanimous decision loss to Stamp Fairtex in the ONE atomweight title fight at ONE Fight Night 14 on September 29, 2023, Seo Hee Ham entered a period of inactivity that extended over two years without any professional bouts.[6] During this hiatus, Ham was unable to compete due to various challenges, marking a significant pause in her otherwise prolific career.[6] On October 20, 2025, Ham announced her departure from ONE Championship and entry into free agency, describing the split as amicable after the end of her contract.[6] At 38 years old, she expressed strong enthusiasm for resuming her fighting career, stating in a social media post, "I’ll come back in a great promotion to show me again!!!!"[6] Ham's perseverance at this stage of her career underscores her dedication to mixed martial arts, as she remains open to opportunities in prominent promotions to continue competing at a high level.[6]Kickboxing career
Professional debut
Seo Hee Ham made her professional kickboxing debut on July 23, 2007, at the CMA Festival 2: Ikuhisa Minowa Debut 10 Anniversary Tournament held in Bunkyo, Tokyo, Japan. The event celebrated the tenth anniversary of Japanese mixed martial artist's Ikuhisa Minowa's professional debut and featured a mix of MMA and kickboxing bouts, providing Ham with an international stage for her first pro fight.[26] Having begun her kickboxing training in 2004 at the Busan Team MAD gym in South Korea—where she trained alongside male athletes due to limited female participation—Ham entered the professional ranks after three years of development focused on striking techniques. Her preparation emphasized a dynamic, kickboxing-centric style that leveraged her taekwondo roots and rigorous sparring sessions to build power and precision in stand-up exchanges.[7] In the debut bout, Ham faced veteran Japanese fighter Megumi Yabushita under three two-minute rounds of kickboxing rules. Despite the challenges of adapting to professional standards, including shorter rounds and heightened pressure compared to amateur competitions, Ham secured a unanimous decision victory (0-3 on the judges' scorecards in her favor), showcasing effective striking to outpoint her opponent and launch her pro kickboxing career.[27]Key bouts and outcomes
Following her professional kickboxing debut, Ham competed in a limited number of bouts, primarily in Japanese promotions during the late 2000s and early 2010s. These matches, often decided by unanimous decision, allowed her to refine her stand-up game, including sharp combinations and leg kicks, against technically sound opponents in three-round formats. One notable bout was her kickboxing rematch against Erika Kamimura at Rise 88 on June 2, 2012, where she lost by unanimous decision after three high-paced rounds.[28] As her MMA career accelerated with entries into promotions like Jewels and Road FC, Ham effectively paused kickboxing around 2012 to prioritize the hybrid format, aligning with her growth as a top atomweight contender. Ham's kickboxing foundation significantly influenced her MMA striking, providing a base for high-volume output and distance management. In her UFC debut against Cortney Casey at UFC Fight Night 79 in 2015, Ham utilized crisp boxing and low kicks, landing 71 significant strikes to her opponent's 78, securing a unanimous decision victory and showcasing the precision honed in kickboxing rulesets.[29] Similarly, during her Road FC tenure, her kickboxing-derived footwork enabled effective counterstriking in stand-up exchanges, as seen in her 2017 knockout of Jinh Yu Frey with a series of punches that echoed pure striking bouts. This integration allowed Ham to evolve stylistically, blending kickboxing aggression with MMA grappling threats, though she never returned to full-time kickboxing amid her MMA success.Championships and accomplishments
MMA titles and awards
Seo Hee Ham has secured multiple championships in prominent Asian MMA promotions, establishing her as a dominant force in the atomweight division during the 2010s. Her title wins and defenses highlight her versatility in striking and grappling, contributing significantly to her reputation as a leading female fighter from South Korea. These accomplishments span promotions like Jewels, Road FC, and Rizin, where she captured and defended belts against top contenders.[4] Ham first claimed major championship gold in Jewels, winning the Featherweight Championship (48 kg) on May 25, 2013, by defeating Naho Sugiyama via unanimous decision in the main event of Jewels 24th Ring.[11] She successfully defended the Deep Jewels Atomweight Championship twice, first against Sadae Numata by unanimous decision on November 4, 2013, at Deep Jewels 2, and then against Saori Ishioka by technical submission (armbar) on November 3, 2014, at Deep Jewels 6. These victories solidified her status in Japan's premier women's MMA scene before vacating the title upon signing with the UFC in late 2014. Returning to Asia after her UFC stint, Ham captured the inaugural Road FC Women's Atomweight Championship on June 10, 2017, stopping Mina Kurobe via TKO (punches) in the third round at Road FC 39.[30] She made two successful defenses, including a first-round knockout of Jinh Yu Frey on December 23, 2017, at Road FC 45, and a unanimous decision over Jeong Eun Park on December 15, 2018, at Road FC 51 XX.[31][18] These defenses showcased her striking power and endurance, maintaining her reign until the promotion's hiatus.[32] In 2019, Ham expanded her resume by winning the Rizin FF Women's Super Atomweight Championship on December 31, 2019, defeating Ayaka Hamasaki via split decision at Rizin 20.[5] This victory avenged a prior loss and marked her as a two-weight class champion across promotions, though she vacated the title in October 2020 without a defense due to scheduling conflicts and a move to ONE Championship.[33] Beyond titles, Ham received the Asia MMA Female Fighter of the Year award in 2018, recognizing her dominant performances and contributions to women's MMA in the region during a year that included her Road FC title win and defenses.[34] Her championships have cemented her legacy as a trailblazer for Asian female fighters, inspiring a new generation with her technical prowess and resilience in high-stakes bouts.[2]| Title | Promotion | Date Won | Opponent | Method | Defenses |

| Featherweight Championship (48 kg) | Jewels | May 25, 2013 | Naho Sugiyama | Unanimous Decision | 2 (Numata, Ishioka) |

Kickboxing achievements
Seo Hee Ham captured the CMA/KPW Women's Lightweight Championship early in her professional striking career, establishing herself as a prominent figure in regional kickboxing promotions in Japan.[35] She successfully defended the title on multiple occasions, including a dominant first-round TKO (punches) against Yumi at Gladiator 59 on August 25, 2013, showcasing her powerful striking arsenal in a pure kickboxing ruleset.[36] Ham also retained the championship via submission (armbar) against Ryo Mizunami in an MMA bout at Gladiator on April 21, 2013, highlighting the versatility of her stand-up game.[35] These accomplishments underscored Ham's technical proficiency in kickboxing, with her precise combinations and knockout power earning praise as foundational elements that enhanced her competitive edge across combat disciplines.[35]Other activities
Media appearances and acting
Prior to her professional fighting career, Ham Seo Hee pursued acting as a child in South Korea, attending a performing arts academy where she developed an interest in stage performance and aspired to become a singer.[9] In fifth grade, she joined a casting agency and secured roles in multiple television shows, including a children's drama in 2000.[9] She also appeared in several TV dramas and participated in a play during this period.[8] Her early acting endeavors ended abruptly before age 17 when her mother destroyed her acting certificates due to Ham's involvement in school fights while defending friends, forcing her to shift focus away from entertainment.[9] Following her rise in mixed martial arts, Ham leveraged her fame for media visibility, appearing in features and profiles on ONE Championship platforms that highlighted her athletic journey and personal background, such as a 2023 pre-fight profile ahead of her interim title challenge.[9] She participated in Korean television programs showcasing her dual identity as an athlete and former performer, including a 2016 appearance on the KBS reality show Rookie, where she discussed her career transition alongside fellow fighter Im So-hee.[37] These opportunities marked an evolution from her coerced departure from acting to using her MMA success for broader public engagement in entertainment media.Public persona
Seo Hee Ham is widely recognized in the mixed martial arts community by her nickname "Hamzzang," a playful Korean term combining her surname "Ham" with "zzang," slang for "the best" or "awesome," symbolizing her elite status among atomweight fighters. This moniker underscores her reputation for exceptional striking ability and unyielding perseverance, traits that have defined her career across multiple promotions. As a South Korean veteran, Ham has cultivated an image as a resilient competitor who thrives in high-pressure stand-up exchanges, often marching forward fearlessly against opponents.[2][4][38] Throughout her career, Ham has openly discussed her thoughts on longevity in the sport, reflecting a thoughtful approach to her professional journey. In a 2021 interview, she revealed plans to retire around age 35 but ultimately chose to extend her tenure, expressing optimism about competing until 40 if her performances remained strong. This decision highlighted her commitment to the sport despite setbacks, including a challenging stint in the UFC. More recently, in October 2025, Ham announced her entry into free agency following a two-year hiatus from ONE Championship, conveying excitement about new opportunities and a desire to reclaim her position at the top of the atomweight division.[39][6] Ham's public persona also emphasizes pride in her perseverance, which she has described as her most significant accomplishment amid numerous titles and victories. In a June 2025 statement, she stressed that enduring the rigors of a long career in women's MMA defines her legacy more than any single achievement. While she has occasionally referenced her experiences in media appearances, her focus remains on advocacy for fair matchmaking and opportunities for seasoned fighters like herself.[40]Professional records
