A first-round finish at RIZIN DECADE
The submission gave Satoshi a decisive result on a card featuring three championship bouts at Saitama Super Arena. His contest ended before the opening round expired, while the other two title fights went to decisions. Kyoji Horiguchi retained the flyweight championship against Nkazimulo Zulu, and Kleber Koike regained the featherweight belt against Chihiro Suzuki.
For Satoshi, the result extended an impressive record within RIZIN. The event report counted 11 victories in his first 12 appearances for the promotion, with 10 of those wins coming inside the distance. That record provides context for the Karamov finish: this was another stoppage in a run already defined by completed fights rather than judges’ decisions.
The triangle choke also makes the full-fight footage a useful companion to the result. The finishing sequence demonstrates why a fighter’s position underneath an opponent does not necessarily mean he has lost the initiative. Satoshi used his guard to create a submission opportunity, bringing the lightweight title contest to an end without needing another round.
