Soma Shinya 相馬 伸哉 · そうま しんや

Soma Shinya (相馬 伸哉) is a 21-year-old professional sumo wrestler from Tochigi Prefecture competing under Futagoyama Stable. His story carries a unique dimension that sets him apart from many of his peers: he is the younger biological brother of stablemate Kotakiyama Kento (小滝山 健人), making them one of relatively few brother duos to compete in the same sumo stable.

At 179.0cm and 148.8kg, Soma has a solid, well-proportioned build that is well-suited to the demands of professional sumo. He made his professional debut in 2023 and has been building his experience and technical foundation through the lower divisions. He reached the Makushita division — the last non-salaried rank in professional sumo — but a 3–4 at East Makushita 60 in March 2026 returned him to the top of Sandanme; a winning 4–3 at West Sandanme 6 in the May 2026 Natsu Basho then earned him a return to the Makushita division, ranked West Makushita 55 on the July 2026 Nagoya Basho banzuke.

Training alongside his older brother Kotakiyama gives Soma a significant advantage: a training partner who knows him intimately, who has already navigated the challenges of professional sumo's lower divisions, and who can provide guidance rooted in direct experience. This sibling dynamic is a noteworthy feature of Futagoyama Stable's roster and a story that sumo fans have followed with interest.

As one of the younger and less-experienced wrestlers in the stable, Soma's immediate goal is to solidify his place in Makushita and build the kind of consistent results that will carry him toward the upper half of the division in the coming tournaments.

Current rank: West Makushita 55 for the July 2026 Nagoya Basho. Career high: Makushita 47.

Trajectory: A 3–4 at East Makushita 60 in March demoted him to the top of Sandanme, but he rebounded with a winning 4–3 at West Sandanme 6 in the May Natsu Basho — earning a return to the Makushita division at West Makushita 55 for the July Nagoya Basho. The next-step target: a winning record here to begin climbing toward his career-high Makushita 47.

His older brother Kotakiyama also competes for Futagoyama — the Soma brothers are part of a stable that already houses three biological brothers, making the family dynamic a basho-by-basho story sumo fans follow with interest.

From Otawara City, Tochigi Prefecture. The middle of three biological brothers all wrestling in the same stable — eldest brother Kotakiyama Kento and youngest brother Shunta are also at Futagoyama (see the Futagoyama Stable page for the full Soma-brothers story). Big fan of the Japanese detective drama "Aibou" — especially the Kameyama Kaoru ("Kame-chan") era. The Soma brothers are known in the stable for being particular about scents and fragrances.
