Few sports can hold spectators spellbound through three-quarters of an hour of tradition before the first point is even contested.
Yet the intricate traditions unfolding in a small clay ring - largely unaltered for centuries - managed to do just that.
This multi-day tournament at the Royal Albert Hall features four dozen top-tier sumo wrestlers showcasing a sport whose first mention dates back to the first century BC.
London's Victorian concert venue has been utterly transformed, complete with a massive traditional roof structure hanging above the dohyō.
It is here the wrestlers, known as rikishi, perform their foot stomping to expel negative energies, and where they applaud to get the attention of the deities.
Above all this ancient ceremony, a massive rotating display - that would fit perfectly at an NBA match - offers the crowd all the statistics and footage they could want.
For an enthusiastic follower, it was a "random video" that first caught her attention a couple of years ago.
This was soon supplemented with the discovery of focused video platforms for sumo stables, where athletes reside and practice, starting their day early to practice, followed by a protein-rich meal and then an daytime sleep - all in the effort toward bulking up.
Another couple discovered sumo through a established path: a journey to Asia six years ago.
"We saw it as a typical visitor experience, but we actually developed passion for the sport," says Julia.
"After that, we tried to locate groups, resources, just to deepen our understanding about it," adds Cezar.
Visiting the homeland is generally the primary approach to see a elite competition.
This London competition marks only the second instance the tournament has visited the city - the initial occasion was in over three decades ago.
Even visiting the country isn't a guarantee of obtaining admission, with the past period seeing fully attended competitions.
For numerous spectators, the London tournament represents the first time they have seen live sumo - and it exceeds expectations.
"Seeing it up close, you get a sense of the speed and the power which you can't experience on TV," explains an attendee. "Their size is impressive."
To succeed, one wrestler needs to push another out of the ring or to the surface using raw power.
The primary group use one of dual approaches to succeed in this, often in moments - thrusting, or wrestling.
Either way, the impact of the two wrestlers colliding in the initial contact of the match resounds around the venue.
The positions right next to the dohyō are of course greatly valued - but also, somewhat dangerous.
During one recent bout, a 191cm wrestler went plummeting into the crowd - perhaps making those in slightly cheaper seats experience comfort.
Of course, the dimensions of the wrestlers is one of the initial aspects most people think of when they think of sumo.
The venue's management revealed they "were required to locate and buy new chairs which can support 200kg in weight."
But sumo - for all its popular tournaments - is not without its troubles behind the scenes.
Perhaps the rigorous lifestyle of a sumo wrestler doesn't look as attractive as it once might have.
Its popularity among the younger generation is also being competed with by alternative competitions, while Japan's decreasing numbers will create further complications.
Not that any of this has concerned enthusiasts in London.
"Experiencing the tradition and practice that is part of sumo is particularly meaningful," fan Sian says. "Currently, observing it directly, you experience being you are more involved."
For other enthusiastic fans, the drama "created amazing experiences" - as did interacting with the fellow enthusiasts.
"Getting out of a particularly focused online community and being able to see all these sumo fans in person and being able to converse with other people who are just as into this as we are - it was absolutely worthwhile."
