Inner -Sumo-

What does it actually take to become a sumo wrestler?

Not the six-second match you see on TV — the other 23 hours and 54 minutes. The 4 a.m. wake-ups. The brutal rank system where a loss can mean scrubbing floors for a senior wrestler. The single enormous communal meal, chanko nabe, eaten together every single day for the rest of your career. The years spent sleeping, training, and eating under one roof with the same 20 men, chasing a promotion that might never come.

Inner Sumo goes past the ring and into the stable — the training, the discipline, the diet, the hierarchy, and the sacrifice behind one of the world's oldest and most demanding sports. Built on real practices, real history, and real accounts from inside the sumo world.

This is sumo with the doors open.
