Just got reminded of this absolute legend in Japan's trading world—Takashi Kotegawa, aka BNF. The guy's story is wild and honestly kind of inspiring if you're into markets.

So here's the thing: he wasn't born rich, didn't go to some fancy trading school, just self-taught himself by studying price action and company fundamentals. Started trading after university during Japan's boom period, but the real moment he blew up was during the 2005 Livedoor scandal. While everyone else was panicking, this guy saw chaos as opportunity and made bank—we're talking over 2 billion yen in just a few years.

But the trade that really cemented his legend? The J-Com disaster in 2005. A Mizuho Securities trader fat-fingered an order—meant to sell 1 share at 610,000 yen but instead placed it as 610,000 shares at 1 yen. Kotegawa spotted it instantly, loaded up on the mispriced shares, and cleaned up when the error got corrected. That's the kind of split-second decision-making that separates the retail traders who make money from the ones who don't.

What's crazy is despite being worth millions, dude lives super modestly. Still takes public transport, eats at cheap restaurants, barely does any media appearances. The mystique around him is real—barely anyone even knows what he looks like.

His whole story is basically proof that in a market dominated by hedge funds and institutions, an individual Japan trader with discipline, timing, and the ability to stay calm under pressure can still absolutely dominate. Not saying it's easy to replicate, but it definitely shows what's possible when you combine skill with opportunity.
