Welcome to the first episode of this new series - Trading Legends. And in this first episode, we are talk about the Bedroom Trader, Takashi Kotegawa from Japan.
But before we move ahead, let me ask you a question.
What does it take to become one of the greatest stock market traders of all time?
Not a Bloomberg terminal. Not a fancy corporate job. Not even a team.
Honestly, Ssmetimes, all it really takes… is a small bedroom, a basic computer, and a mind that refuses to panic.
Welcome to the story of Takashi Kotegawa - famously known as BNF or Japan’s Bedroom Trader.
A man who started with the equivalent of ₹8- 9 lakhs and turned it into billions of yen, quietly, anonymously, without ever seeking fame.
This video takes you deep into one of the most legendary and unbelievable real stories in global stock market history.
Before he became a myth, Takashi was an ordinary young man from Ichikawa - a middle-class Japanese town far from Tokyo’s financial world. No finance degree, no investment bank pedigree, no inside network.
While his friends took up office jobs, Takashi stayed in his room with a second-hand computer, studying charts, human psychology, and panic behavior in the market.
This video explores how he turned his early savings of ¥1.6 million into a fortune - simply by understanding how fear works and what happens when an entire market loses its mind.
On 8 December 2005, Japan witnessed one of the biggest trading blunders ever seen.
A trader at Mizuho Securities mistakenly placed an order to sell 610,000 shares at ¥1 instead of 1 share at ¥610,000.
A catastrophic typo.
Billions of dollars evaporated. The Tokyo Stock Exchange froze. Japan’s market went into shock.
But in the middle of this chaos, one man stayed completely calm.
Takashi Kotegawa quietly observed the charts, noticed the mispricing, and executed a series of razor-sharp trades.
While brokers were panicking, he was calculating.
In a few minutes, Kotegawa made 2 billion yen (around $16 million at the time) — all from one legendary trade.
This video breaks down that moment step-by-step, showing how discipline, patience, and emotional control made him a legend.
Unlike modern traders flashing screenshots, showing off cars, or selling courses, Takashi built his wealth in silence: No publicity, No interviews, No social media.
His method was simple: Observe panic. Enter when the last scared seller is exhausted. Exit when confidence returns.
We explore his trading rules, mindset, routines, and the psychological frameworks that allowed him to survive dot-com crashes, Japan’s lost decade, and even the 2008 global meltdown - while most traders got wiped out.
Watch his masterclass of Psychology that Takashi Kotegawa displayed all across his trading journey.
