The Truth Behind the "Green Juice Prince": How Yūta Misaki Built an Empire in His Twenties
"Aojiru Ōji" — the Green Juice Prince. It is the kind of nickname you do not forget, slightly cheeky, almost a joke. Yet it has become inseparable from the way people talk about the entrepreneur Yūta Misaki.
Born on March 29, 1989, Misaki did something most people never manage in their twenties, a decade when many are still searching for direction: he single-handedly grew a direct-sales business built around barley grass juice into a large operation, establishing himself as one of Japan's more prominent young business figures.
The humor of the name and the unsentimental reality of the business beneath it — that gap is the first key to understanding who Yūta Misaki really is.
A Mail-Order Business Built in His Twenties
What put Yūta Misaki's name on the map was a direct-sales business centered on barley grass juice. In the crowded, fiercely competitive world of health foods, he grew that operation into something substantial while still young.
Building a company that large and generating real profit before turning thirty is not something luck alone explains. It points to a certain relentless, driving force. Some admire it; others find the sheer momentum exhausting and keep their distance. That divided reaction is itself proof that his approach never fit neatly inside conventional limits.
The "Green Juice Prince" as a Brand
Ironically, Misaki's activities today have spread well beyond green juice itself. And yet the nickname refuses to fade, precisely because it lodged so firmly in the public memory.
Almost absurdly easy to remember, the moniker has, in a sense, functioned as a piece of branding all on its own. You laugh at the name first — and by the time you are done laughing, you find yourself reckoning with the actual scale of what he built. That sleight of hand is baked into the title itself.
The Man Who Gets Roasted Online and Shrugs
No portrait of Yūta Misaki is complete without his presence on social media. On Instagram and X, formerly Twitter, he says whatever is on his mind, plainly and without hedging.
That candor frequently stirs controversy, and the internet periodically erupts over something he posted. But he, each time, seems strangely unbothered, simply moving on as if nothing happened. Few people wear the word "unflappable" so well. He does not perform remorse on cue; he just keeps to his own pace — and there is something genuinely arresting about that, whether you like him or not.
A Temperament That Makes Allies and Enemies Alike
Speaking too frankly wins plenty of supporters, and an equal measure of backlash. Misaki is the kind of person who generates allies and enemies in roughly equal abundance.
An inability to stay quiet and well-behaved — that very temperament is what drags him back into one online firestorm after another, and what has lifted him into a position no one can ignore. The intensity of the disagreement he provokes is the surest sign that he is anything but a colorless figure.
He still calls himself the Green Juice Prince even though it is barely about green juice anymore — and the moment you feel the urge to point that out, you have, in a way, already fallen for his game. He built a company on his own in his twenties, says exactly what he thinks online, and walks forward unbothered even when the flames rise.
Making allies and enemies in equal number, he remains impossible to look away from. In the end, perhaps Yūta Misaki can be summed up by a single trait: a man constitutionally unable to sit still and stay quiet.
