Isao Machii isn’t your average martial artist. He’s a living legend — a samurai in the modern world who holds multiple Guinness World Records for sword speed and precision.
From slicing through moving baseballs to cutting a bullet fired at him from point-blank range, his skills have stunned scientists, martial arts experts, and millions of viewers around the globe.
Machii’s speed isn’t just about reflexes — it’s about intense training, focus, and razor-sharp technique passed down from centuries of samurai tradition.
In one of his most jaw-dropping demonstrations, he uses a katana to slice through a pellet traveling at over 200 mph. High-speed cameras slow it down for proof — but to the human eye, it looks impossible.
This isn’t just martial arts.
This is mastery at its peak.
Check the video below and see why Isao Machii is called the fastest swordsman alive — and how he continues to push the limits of what the human body can do.
