Profile

Kotakiyama Kento (小滝山 健人 · furigana こたきやま けんと), real name Soma Kento (相馬 健人), occupies a unique and historically significant place at Futagoyama Stable: he is the longest-serving active wrestler, having joined when the stable was first established in 2018. Born January 9, 2003 in Otawara City, Tochigi Prefecture, Kotakiyama has been part of the stable's story from its very first days — making him a senior figure within the dojo regardless of his current ranking.

Per the JSA, he stands 184.7cm and weighs 136.0kg, Kotakiyama has the frame of a capable upper-division competitor. He holds the designation of uchi-deshi (内弟子), or inner disciple — a wrestler who lives in the stable master's household and receives direct personal instruction from the oyakata. This is a position of great trust and reflects the close relationship between Kotakiyama and stable master Futagoyama that has developed over nearly a decade.

His career high of Makushita 37 was reached in November 2023, demonstrating genuine ability at the mid-Makushita level. Since then, his trajectory has been more modest, but his seniority and experience make him an invaluable training partner and mentor within the stable.

Adding to his unique story, Kotakiyama is the older biological brother of Soma Shinya (相馬 伸哉), who also competes at Futagoyama Stable. Both brothers hail from the Otawara area of Tochigi, and the fact that they share not just a family background but also a professional home is a notable element of Futagoyama Stable's human story. Kotakiyama's path through the professional ranks has provided his younger brother with an experienced guide and training partner from within the same family.

🚧 Where Kotakiyama Sits — The Path Forward

Current rank: East Sandanme 66 for the November 2026 Kyushu Basho (November 8–22, Fukuoka Kokusai Center). Career high: Makushita 37 (November 2023).

Trajectory: A winning 4–3 at East Sandanme 64 in March 2026 earned promotion to East Sandanme 44, where he posted a losing 2–5 in the May Natsu Basho — dropping him to East Sandanme 68 on the July Nagoya banzuke. At Nagoya he answered with a 5–2, and that winning record lifted him 30 places to East Sandanme 38 for the September 2026 Aki Basho (September 13–27, Ryogoku Kokugikan), but a 2–5 there sent him back down 28 places to East Sandanme 66 for the November 2026 Kyushu Basho. The next-step target: a winning record at Kyushu to start climbing back toward upper-Sandanme and, eventually, his Makushita 37 career high.

Futagoyama's longest-serving active wrestler — he debuted in March 2018 when the stable was founded. As uchi-deshi (inner disciple) of stable master Futagoyama, he holds a position of seniority distinct from rank. He is also the eldest of the three Soma biological brothers all wrestling at Futagoyama.

FAQ

Who is Kotakiyama Kento? ▼
Kotakiyama Kento (小滝山 健人) is a 23-year-old professional sumo wrestler from Otawara, Tochigi, competing for Futagoyama Stable. He is the longest-serving active member of the stable, having debuted when it was founded in 2018. His career high is Makushita 37 (November 2023), and he is the elder brother of stablemate Soma Shinya. He serves as uchi-deshi (inner disciple) to stable master Futagoyama.
What does 'inner disciple' (uchi-deshi) mean in sumo? ▼
In professional sumo, an uchi-deshi (内弟子) is a wrestler who lives in the stable master's private household rather than the communal stable dormitory. This arrangement places the wrestler under the direct personal supervision and tutelage of the oyakata (stable master), and it implies a particularly close relationship between the two. Being designated an uchi-deshi is considered an honor and a sign of trust, reflecting the stable master's personal investment in that wrestler's development.
Is Kotakiyama the brother of Soma Shinya? ▼
Yes. Kotakiyama Kento is the elder biological brother of Soma Shinya (相馬 伸哉), who also competes at Futagoyama Stable. Both brothers are originally from the Otawara area of Tochigi Prefecture. Competing in the same professional sumo stable as a biological sibling is relatively uncommon, and the Kotakiyama-Soma brother duo is one of the more charming storylines at Futagoyama Stable.
What does it mean to be Futagoyama Stable's longest-serving member? ▼
Futagoyama Stable was re-established in 2018, and Kotakiyama Kento was among the very first wrestlers to join. This makes him the wrestler with the longest continuous service at the stable — he has been part of its history since before it had its first tournament, before it acquired any of its current roster, and well before younger members like Soma, Takahara, or Shunta were even thinking about professional sumo. This seniority carries real social weight within the strict hierarchy of sumo stable life.
