A “future person” named Rei Kokubun—who claims to have come from the year 2058—is once again making headlines. Online, he’s being called “Japan’s strongest future person,” and it seems his past prophecies have apparently come true in many ways, which is apparently why his followers are growing. There are parts where his predictions actually match reality, such as the number of gold medals at the Tokyo Olympics, the Nikkei average crash in 2020, and the timing of former Prime Minister Abe’s resignation.

Rei Kokubun says he was born in 2034 and that he was at the Faculty of Engineering, Department of Architecture, at Tokyo National University. He claims that in December 2019, he came to this era via a time-and-space transfer device. There’s no scientific evidence, but he became a well-known figure on social media after a series of predictions posted on X.

For cryptocurrency investment advice, Rei Kokubun seems to be focused on Ethereum. Between December 2019 and early 2020, he supposedly bought a large amount of about 1,400 ETH using his father’s account, put it into a hardware wallet, and buried it in his parents’ backyard. He plans to dig it up in 2058. The reason he chose Ethereum instead of Bitcoin is reportedly that he believed the Ethereum ecosystem has higher application potential and greater upside.

However, Rei Kokubun also makes comments about the situation in 2058. He says Bitcoin will reach astonishingly high prices, but that it’s “something you can only sell, not buy.” The idea is that if Bitcoin eventually reaches 780 million yen (about $4.94 million), it could mean that new acquisition methods become restricted—or that the inherent characteristics of Bitcoin itself could become unsuitable for trading. Since BTC is currently $77.14K and ETH is $2.28K, the future value of Bitcoin is indeed beyond imagination.

That said, when you look closely at Rei Kokubun’s past “success stories,” it raises questions about whether everything is truly “divinely accurate.” Predictions about an economic downturn or political changes might have been inferred from the economic conditions and political rumors of the time, and people have also pointed out the possibility of luck playing a role or later adjustments being made.

Online, many voices are skeptical about time travel. There are also claims that Rei Kokubun’s statements contain a lot of ambiguity—that perhaps he’s trying to capture users’ attention with vague hints.

No matter what the truth is, Rei Kokubun has once again drawn attention to the long-term potential of digital assets such as Bitcoin and Ethereum. Investment experts say that even if you follow predictions about future value, it’s important first to assess your own risk tolerance.

There are concerns that his remark, “Bitcoin is only for selling,” could lead to further speculation or trigger panic selling. Since 2024, the prices of Bitcoin and Ethereum have fluctuated significantly due to positive catalysts such as U.S. elections and ETF introductions, so it’s important for investors to stay calm even amid the hype.

In the end, Rei Kokubun’s identity as a “future person” and his prophecies remain shrouded in mystery. It may be an entertaining media topic for the crypto market, but for his followers, he’s probably seen as a “prophet” guiding them. Still, regardless of whether you believe in information from the future, when it comes to investing, the most important things are independent judgment and risk management.
