They finally did it! A video with two of the absolute BIGGEST stars in snowboarding that just happen to be brothers. Japan legends Ayumu and Kaishu Hirano are the focus in the latest video from Monster, documenting their historic careers full of records, medals, family and respect from every single pro in the game.

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.
