Marcus Skin followed the Hirano brothers to find out what was the secret behind their incredible talent.

Kaishu and Ayumu Hirano didn’t follow the trajectory of snowboarding—they bent it to their will. Burazazu is a raw, unfiltered look at two brothers who turned obsession into dominance, and discipline into something bordering on myth.

Raised in a household where progression was non-negotiable, the Hiranos forged their edge early—pushing each other harder, faster, and further than anyone around them thought reasonable. This isn’t a feel-good origin story. It’s about pressure, repetition, risk, and a brotherhood sharpened by expectation.

From concrete ramps in Japan to Olympic gold and world-record halfpipe runs, Burazazu captures how Kaishu and Ayumu rewired snowboarding. Precision over chaos. Fearlessness over comfort. Style with consequence.

This is what happens when talent meets obsession—and refuses to slow down.
