There's Nothing Like Feeling the Historic London Venue Tremble When Rikishi Meet
Not many athletic disciplines can keep viewers enthralled through 45 minutes of ceremony before the first point is even determined.
Yet the detailed ceremonies unfolding in a traditional dohyō - mostly preserved for centuries - succeeded in doing so.
Welcome to the Prestigious Rikishi Event
This week-long competition at the iconic London venue features four dozen top-tier sumo wrestlers showcasing a sport whose earliest records dates back to the first century BC.
London's historic performance space has been totally redesigned, complete with a six-tonne Japanese temple roof hanging above the competition area.
Ancient Traditions Meet Contemporary Displays
It is here the competitors, known as sumo professionals, perform their shiko exercises to expel negative energies, and where they clap to attract the gods.
Above all this historical practice, a enormous circular monitor - that would fit perfectly at an professional sports event - offers the crowd all the data and video they could want.
International Enthusiasts Embrace Sumo
For an enthusiastic follower, it was a "chance online clip" that first drew her interest a couple of years ago.
This was soon supplemented with the discovery of specialized online content for sumo stables, where wrestlers live and train, waking up early to practice, followed by a protein-rich meal and then an daytime sleep - all in the effort toward bulking up.
From Edinburgh, Different Experience
Julia and her partner Cezar discovered sumo through a more traditional route: a journey to Asia six years ago.
"We considered it a typical visitor experience, but we actually developed passion for the sport," says Julia.
"After that, we tried to locate groups, resources, just to learn more about it," the other fan explains.
Rare Opportunity
Going to Japan is generally the primary approach to see a major championship.
This London competition marks only the second time the tournament has come to London - the first time was in over three decades ago.
Even going to Japan doesn't ensure of securing tickets, with recent years seeing fully attended competitions.
Live Observation
For multiple fans, the current event represents the premier chance they have watched sumo in person - and it doesn't disappoint.
"Seeing it up close, you get a understanding of quickness and the strength which you won't feel on TV," notes one fan. "Their stature is remarkable."
The Bouts
To succeed, one rikishi needs to force his opponent out of the ring or to the floor using raw power.
The most use one of dual approaches to succeed in this, often in split seconds - pushing, or grappling.
Either way, the sound of the two athletes colliding in the opening second of the match reverberates around the hall.
Premium Seating
The seats right next to the ring are of course extremely sought-after - but also, somewhat dangerous.
During one particular match, a tall wrestler fell into the crowd - perhaps making those in more affordable locations feel relieved.
Organizational Issues
Of course, the stature of the athletes is one of the primary elements most people think of when they consider the sport.
The hall's organizers revealed they "had to source and acquire reinforced furniture which can support 200kg in weight."
But sumo - for all its popular tournaments - is not without its troubles behind the scenes.
Coming Obstacles
Perhaps the demanding existence of a professional athlete doesn't look as attractive as it once might have.
Its following among youth in Japan is also being challenged by other sports, while Japan's falling birthrate will present additional challenges.
International Network
Not that any of this has worried fans in London.
"Witnessing these custom and formality that accompanies sumo is particularly meaningful," an attendee explains. "Now, seeing it directly, you sense that you are more engaged."
For other dedicated followers, the excitement "created amazing experiences" - as did interacting with the like-minded individuals.
"Emerging from a very niche online community and being able to witness multiple sumo fans live and being able to speak to other people who are just as into this as we are - it was absolutely worthwhile."
