Sumo, the iconic Japanese sport of strength and agility, has deep roots that stretch back centuries. While often thought of as a uniquely Japanese tradition, similar forms of wrestling have been practiced across the globe for millennia. From ssireum in South Korea to boke in Mongolia, physical contests involving strength and skill have been a part of human culture for years.

In Japan, evidence of sumo can be traced back to the Kofun (between the third and seventh centuries) period, with figurines of sumo wrestlers unearthed from this era. The sport even holds a place in the country's mythological history, mentioned in both the Kojiki and Nihonshoki. Initially, sumo was performed as a ritual to pray for bountiful harvests. Over time, it evolved into a spectacle for the imperial court during the Nara (710–794) and Heian periods (794–1185).

The age of the samurai brought a new dimension to sumo. Physical prowess was paramount for warriors, and samurai families often employed sumo wrestlers. Oda Nobunaga, one of Japan's most famous warlords, was a passionate sumo fan, hosting annual tournaments.

It was during the Edo period (1603–1867) that sumo truly took shape as we know it today. As the sport gained popularity among the masses, it became a source of entertainment and fundraising. To regulate the often chaotic matches, a standardised set of rules was established, including the iconic circular ring. Sumo stables were created, and the sport became a microcosm of traditional Japanese culture, complete with elaborate rituals and attire.

Today, sumo remains a beloved national treasure in Japan. Sumo wrestlers are more than just athletes; they are cultural ambassadors, carrying the traditions of their country to the world.
