The so-called “Japan’s strongest future person,” Rei Kokubun, who’s been trending online, is attracting attention again. This person, who has allegedly predicted things like the number of gold medals at the Tokyo Olympics, a major crash in the Nikkei stock average, and political turning points, is revered by his supporters.

According to Kokubun’s latest claims, he was born in 2034 and, in December 2019, came to today using a spacetime teleportation device. He says that, right at the time, he planned to make a large-scale purchase of about 1,400 Ethereum, bury it in his parents’ yard, and dig it up in 2058. As for why it isn’t Bitcoin, he says the growth potential of the ecosystem and the opportunities for applications are more appealing.

What’s especially interesting, though, is what he says about Bitcoin. In Kokubun’s story, in the future of 2058, Bitcoin will reach astonishingly high prices, but at that point, he claims it will only be possible to sell. In other words, many people interpret his words as a message that there’s still room to buy right now.

That said, there are doubts among researchers as to whether all of his past prophecies truly came true. Some argue that what can be inferred from economic trends and political rumors might be enough, and that he could be retroactively “making up” things with vague wording.

From an investment perspective, there’s no question that Kokubun’s words are reigniting interest in Bitcoin and Ethereum. However, experts point out that it’s more important to seriously assess your own risk tolerance than to rely on “messages from the future.” Markets can swing dramatically due to factors such as elections and the introduction of ETFs.

In the end, whether Kokubun is a real time traveler or just a cleverly crafted online hype creator remains a mystery. It may be an intriguing kind of speculation or promotion for the crypto market, but investment decisions should stay calm—put your own judgment and risk management first.
