Hayato Waterfall posts his statement: In March, he made 25.73 million yen from currency trading. Stock god? The money lost in stock trading probably hasn't been recovered yet.

On March 5, Beijing time, Jun Mizutani, the 36-year-old Tokyo Olympics table tennis mixed doubles gold medal winner, updated his status on Twitter that day. He reported that his FX (foreign exchange margin trading) performance in March was outstanding, netting a profit of 25.73 million yen (about 1.0666 million RMB).

Jun Mizutani is a relatively high-profile person. After retiring, he often proactively shares on social media the gains and losses from his stock trading and FX trading. He is quite a gambler and often ends up losing big. But today, Jun Mizutani made a high-profile announcement—he’s made money.

His total realized profit and loss for the month of March was 24,731,200 yen. He wrote, “FX also performed well in March. It’s been a full year since I started doing FX. Although there have been ups and downs, I feel like I’m constantly absorbing experience and growing.” Then he added, “Most importantly, it seems I’ve found a clue to a way to do it…” In January, he had reported a “profit of about 21 million yen (from FX trading).”

The post sparked heated discussion among netizens. Comments included: “Someone who’s been through countless Shura battlefields and has extremely strong mental resilience is most likely to become the strongest trader!” “Please take me as your disciple!” “The day the FX god is born is getting closer and closer!” “Teach me how to make money,” and so on.

Has Jun Mizutani transformed into a stock guru because of this? Has he transformed into the strongest trader? He previously lost a lot of money trading stocks, so it’s likely he still hasn’t broken even.

From 2023 to 2024, he mainly played the stock market, with a huge cumulative loss over 7 years. He once revealed on a show: “In 7 years of stock trading, I’ve never been profitable even once. The money I lost would be enough to buy a house in Tokyo.” The amount he lost in 2024 was equivalent to “buying a high-end imported sedan.”

In 2025, he continued to show off his results in a high-profile way, reporting losses of large amounts multiple times—such as once losing more than 16 million yen (about 690,000 RMB), and once suffering a loss described as a “high-end Lexus LS-class” loss. He publicly stated that his overall performance in 2025 was still a losing year: “I lost both the house and the Lexus LS.”

Daily News, Sankei News, Sponichi, and other major Japanese mainstream media reported that in early March, Jun Mizutani’s main positions were FX in Turkish lira. Around March 23, Jun Mizutani reported executing multiple GBP/JPY trades and profiting. At the same time on the stock side, he held Nikkei double inverse ETFs, which at one point were down close to 20 million yen (about 860,000 RMB). Later, when the Nikkei dropped sharply, he turned from loss to profit again, with earnings of about 4.4 million yen (about 190,000 RMB).

After retiring, Jun Mizutani’s investment performance has swung wildly. He has had several instances of million-yen-plus profit in a single month, and even within a single week, but also multiple instances of losses in the tens of millions. As of April 2026, he still hasn’t stopped his high-profile posting of results; overall, he remains in a state of “learning while losing and earning while making profits.” Media and netizens generally believe that he has brought athletes’ “win-or-lose” mindset into his investments, but the risk is relatively high due to both high leverage and emotional trading.
