From our friends at Monster Energy: 

Kaishu and Ayumu Hirano didn’t follow snowboarding’s playbook—they rewrote it. Burazazu is a raw, no-polish look at two brothers who turned obsession into dominance and discipline into something almost unreal.

Raised in a household where progression wasn’t optional, the Hiranos sharpened each other early—pushing harder, faster, further than anyone thought made sense. This isn’t a feel-good origin story. It’s pressure, repetition, risk, and a brotherhood forged by expectation.

From concrete ramps in Japan to Olympic gold and record-breaking halfpipe runs, Burazazu shows how Kaishu and Ayumu bent snowboarding toward precision over chaos, fearlessness over comfort, style with real consequence.

This is what happens when talent meets obsession—and never hits the brakes.
