Sumo X: How Ancient Tradition Meets Modern Athletic Innovation

For centuries, professional sumo has stood as a bastion of unyielding tradition. Steeped in Shinto ritual, strict stable (heya) hierarchies, and centuries-old customs, the sport was long viewed as culturally insular—an experience best witnessed during tournament months in Japan or through specialized broadcasts.
