Rei Kokubu, a self-proclaimed “future person” who says she has come from the year 2058, is once again making headlines. On the internet, she’s being called “Japan’s strongest future person.” She has drawn attention because some of her predictions have come true in the past. The number of gold medals at the Tokyo Olympics, the stock market crash in 2020, and the timing of former Prime Minister Abe’s resignation… since these events actually happened, her followers have started to believe her words wholeheartedly.

According to Rei Kokubu, she was born in 2034 and was enrolled in the Department of Architecture in the Faculty of Engineering at the Tokyo University of National—an institution called 東京国立大学. She says that in December 2019, she used a spacetime transfer device to come to the present. Well, whether there is scientific evidence for time travel is another matter, but her sequence of prediction posts on X went viral, and she has now become a well-known figure on social media.

What’s especially interesting is Rei Kokubu’s investment strategy for crypto assets. She claims that between December 2019 and early 2020, she used an account registered in her father’s name to purchase about 1,400 Ether (ETH) tokens in large quantities. Why not Bitcoin, but Ethereum? She says that’s because she believed the Ethereum ecosystem offers more application opportunities and has higher upside potential. She also says she stores these tokens in hardware wallets that are buried in her parents’ yard, and that she plans to dig them up in 2058.

However, Rei Kokubu has also made some intriguing comments about Bitcoin. By the year 2058, Bitcoin will have reached a remarkably high price, but at that point, she says it will be a situation where “you can only sell, and you can’t buy.” Based on her calculations, if Bitcoin reaches roughly 780 million yen, the means to make new purchases may become extremely limited, or Bitcoin’s liquidity could decline. Her supporters are excited by this information and interpret it as “there’s still room to buy Bitcoin while you can,” but some warn that caution is necessary for a long-term strategy.

That said, if you think about it calmly, there are also claims that not all of Rei Kokubu’s past “hits” are completely divinely accurate. Predictions about an economic downturn or a political change were likely inferred from the economic trends and political gossip of the time, and there may also be elements of luck and post-hoc interpretations. Moreover, the future events she mentions cover a very wide range—stock markets, pandemics, politics, earthquakes, infectious diseases, and crypto trends—so it becomes easier for a “some of them will come true” pattern to work.

Most of the scientific community and the media are skeptical about time travel. Even within Japan, there are voices pointing out that Rei Kokubu’s statements contain a lot of ambiguity. There’s even speculation that she may be trying to draw users’ attention by using vague hints.

In any case, Rei Kokubu’s existence has sparked debate among crypto asset investors and has once again brought attention to the long-term potential of Bitcoin and Ethereum. Investment experts say that if you want to follow her “future value in the 2030s,” you first need to calmly assess your own risk tolerance.

On the other hand, some people worry that her statement—“Bitcoin can only be sold”—could lead to excessive speculation and desperate selling at discounted prices. Since 2024, Bitcoin and Ethereum have been seeing major fluctuations driven by factors such as U.S. elections and ETF introductions, so it’s important to stay level-headed amid the hype.

In the end, whether Rei Kokubu is truly a future person or whether it’s a cleverly staged gimmick remains a mystery. For crypto markets, it might be an interesting media topic, but investment decisions are always based on personal responsibility and risk management. No matter whether you believe in future information or not, you have to keep an eye on market developments and real-world changes, and move forward carefully step by step.
