Satoshi Ichinokura, the defensive specialist of Sannoh High School in Slam Dunk, is one of the key contributors to the team’s reputation as Japan’s most disciplined and suffocating basketball powerhouse. Representing Akita Prefecture’s reigning national champions, Ichinokura personifies coach Goro Domoto’s philosophy of precision, effort, and control. Though not one of Sannoh’s headline stars, his defensive prowess and mental toughness make him indispensable to the team’s success.

Ichinokura’s role is clear: stop the opponent’s best perimeter scorer. His lateral quickness, anticipation, and stamina allow him to shadow players relentlessly, cutting off passing lanes and forcing turnovers. Whether through tight on-ball pressure or help defense, Ichinokura disrupts offensive flow and frustrates even the most talented rivals. His dedication to defense reflects the heart of Sannoh’s system — collective effort and self-sacrifice over personal glory.

In the National Tournament, during Sannoh’s dramatic clash with Shohoku, Ichinokura is assigned to contain Hishashi Mitsui, the three point sharp shooter.
