Great-O-Khan

Tomoyuki Oka, known worldwide as Great-O-Khan, is a Japanese professional wrestler signed to New Japan Pro-Wrestling. He is a dominant force in the heavyweight division, recognized for his Mongolian warrior gimmick and powerhouse style. As a member of the United Empire stable, he holds multiple championship titles, including the NEVER Openweight 6-Man Tag Team Championship and the IWGP Tag Team Championship. Great-O-Khan is a five-time IWGP Tag Team Champion, a former NJPW World Television Champion, and the final KOPW champion. His imposing presence and technical skill have made him a standout in NJPW's tag team scene. Fans admire his intensity in the ring and his heroic off-screen act of saving a young girl from an attacker in 2022, which earned a letter of appreciation from Kawasaki City Police.[edit]

Tomoyuki Oka was born on June 12, 1991, in Maebashi, Gunma Prefecture, Japan. He developed a passion for professional wrestling early on and enrolled at the New Japan Pro-Wrestling Dojo, where veteran wrestler Yuji Nagata trained him. During his amateur wrestling training, Oka taught sessions in Portsmouth, England, as part of his excursion. On the first day, over 20 students showed up, but after a grueling second session, only two returned. He made his professional debut on February 25, 2016, under his real name as a Young Lion, competing in undercard matches to build his foundation. He spent several years in the Young Lion ranks, departing for a learning excursion to England in 2018, where he wrestled for Revolution Pro Wrestling and developed the Great-O-Khan persona.[edit]

Great-O-Khan's breakthrough came on October 16, 2020, when he returned from his English excursion as the Mongolian warrior Great-O-Khan and joined the United Empire. In 2021, he won his first championship, the IWGP Tag Team Championship, with Jeff Cobb, a title he would go on to win five times: twice with Cobb, twice with Henare (current), and once with Callum Newman. He expanded his reach in 2022 by appearing on AEW television at the Forbidden Door pay-per-view. Over the next few years, he captured the KOPW Championship (as the final official holder) and the NJPW World Television Championship. He also won the RevPro British Heavyweight Championship, RevPro British Tag Team Championship, ROH World Tag Team Championship, and SWE Tag Team Championship. As of 2026, he holds the NEVER Openweight 6-Man Tag Team Championship with Henare and Will Ospreay, and the IWGP Tag Team Championship with Henare, cementing his status as a top tag team competitor. He has wrestled 834 matches as of early 2026, including 15 pay-per-view events.[edit]

Great-O-Khan presents a Mongolian warrior persona with fur-trimmed attire, war paint-style face markings, and a commanding presence. His in-ring style blends power moves with technical wrestling, fitting his heavyweight frame. Media outlets portray him as a dominant enforcer within the United Empire. Fans appreciate his intensity and his heroic off-screen act of saving a young girl, which earned widespread praise. He maintains a professional tone on social media, posting primarily in Japanese with occasional English updates. His international fanbase grew after his AEW appearances and English excursion.[edit]

Great-O-Khan currently holds no placement in the iFANN Global Top 1,000 or any scope-specific ranking list. The iFANN Global Fame Engine has evaluated his profile but determined he does not yet occupy a published position among the world's most famous figures. While his name resonates deeply within the wrestling community, he lacks a specific numeric rank on the global scale. His audience identifies primarily as New Japan Pro-Wrestling supporters rather than members of a distinct, named faction like 'The Khan-ites'. Fans rally around the United Empire stable, driven by the group's cohesive aesthetic and the intense loyalty shown to its leader, Will Ospreay. This collective identity manifests in online debates regarding cross-promotional storylines and shared anticipation for the faction's synchronized entrances. There are no documented fan-funded campaigns, birthday billboards, or unique rituals exclusive to Great-O-Khan himself. Instead, his connection with the audience is built on high-stakes athletic performances and the compelling narrative of the British Invasion. Supporters celebrate his role as the enforcer who helped elevate the entire group to championship status, viewing his stoic presence as a cornerstone of modern NJPW storytelling.[edit]

His ring name and gimmick draw direct inspiration from Genghis Khan, the founder of the Mongol Empire. During an English excursion, he visited the Tower of London and Glastonbury Abbey, associating them with King Arthur. He once taught amateur wrestling in Portsmouth, where an intense session reduced a class of twenty students down to just two. In a 2022 interview, he reflected on this anecdote and expressed gratitude to Lord Gideon Grey for his hospitality. The Kawasaki City Police awarded him a letter of appreciation for rescuing a young girl from a drunken predator in 2022; he subdued the attacker and offered the girl pancakes. As of early 2026, he has wrestled 834 matches. His billed weight of 120 kg makes him one of the heavier competitors in NJPW. His Instagram handle is @o_kharn and his X (Twitter) handle is @OkaTomoyuki. A legendary moment occurred when he returned to NJPW to interfere in a match between Will Ospreay and Kazuchika Okada, helping Ospreay win and immediately forming the United Empire stable. Another enduring story involves the complex narrative of Ospreay signing with AEW while remaining loyal to the faction, a plot point that sparked intense discussion among fans about cross-promotional alliances.[edit]

Great-O-Khan keeps his family life extremely private. No public information exists about his parents, siblings, or extended family. He has never discussed his upbringing or household in interviews. As of 2026, he is not known to have a spouse or children. He resides in Japan, but details about his home life remain undisclosed.[edit]

Great-O-Khan has kept his romantic life entirely private. No public relationships, marriages, engagements, or children have been confirmed by credible sources. He has not addressed his relationship status in interviews. As of 2026, his relationship status is unknown.[edit]

Updated for 2026, Great-O-Khan's net worth is estimated at $1 Million per iFANN's editorial analysis. His income primarily comes from his NJPW contract, which includes a base salary and bonuses for pay-per-view events and title matches. He also earns from independent bookings with Revolution Pro Wrestling in the UK, from merchandise sales, and from his appearance at AEW's Forbidden Door in 2022. Unlike many Western wrestlers, NJPW talent rarely disclose financial details, so this figure stands as a researched estimate based on industry benchmarks for mid-to-upper card talent.[edit]
