Supervisor・Tsuyoshi Mizuguchi

He began practicing sumo in sixth grade, later advancing to Hotoku Gakuen High School and Ritsumeikan University before joining the Kasugayama stable to enter professional sumo. After retiring in 2016, he appeared in a popular subscription-based drama series titled Sanctuary. Currently, he runs his own YouTube channel, “Osumo Gucchan-neru,” where he shares videos on sumo training, techniques, and his experiences from his time as a professional wrestler.

Sumo is not only a sport in Japan but also a deeply rooted cultural ritual. Among the many forms of sumo, Ōzumō stands out as a structured, professional spectacle filled with centuries-old traditions. For those visiting Japan, understanding the difference between regular sumo and Ōzumō offers a unique insight into Japanese values and heritage.

What Is Sumo? A Sacred Martial Art Rooted in Japanese Tradition

Sumo is a traditional Japanese martial art that emphasizes not only combat but also spirituality and etiquette. Its origin lies in Japan’s ancient Shintō rituals, where it was performed to pray for a bountiful harvest. Historical records from the Nara period include the “Sumai no Sechie,” a court ceremony involving sumo, demonstrating its long-standing connection to religion and state.

Sumo’s basic rule is simple: two wrestlers face off in a circular ring and attempt to push each other out or make the opponent touch the ground. However, before and after the bout, rituals like shiko (stomping), salt throwing, and bows are performed to purify the space, reflecting the sport’s spiritual nature. Even today, sumo is practiced at local shrines, schools, and community events, showing how deeply embedded it is in daily Japanese life.


What Is Ōzumō? A Structured Professional Sport

Ōzumō is a professional sport governed by the Japan Sumo Association. It evolved from temple offerings and street entertainment in the Edo period into a fully organized and commercialized system. Today, six official tournaments (honbasho) are held annually in Tokyo, Osaka, Nagoya, and Fukuoka, drawing spectators nationwide.

Wrestlers (rikishi) belong to sumo stables (heya) where they live and train under strict discipline. Their daily lives, attire, and even hairstyles reflect traditional Japanese culture. Rankings such as Yokozuna, Ōzeki, Sekiwake, Komusubi, and Maegashira are based on performance, and a rikishi’s status determines their income and privileges. In this way, Ōzumō is not only a sport but a living representation of cultural heritage.

Foreign rikishi must adapt to Japanese language, customs, and lifestyle, often living communally with strict rules. Yet those who succeed earn deep respect and play a vital role in increasing sumo’s diversity and global appeal.
