It’s Ling Kokubun, who supposedly came from the year 2058, and he’s back in the spotlight again. Online, he’s apparently called “Japan’s strongest future person,” and quite a few people believe him because some of his past predictions have come true—like the number of gold medals at the Tokyo Olympics, the stock market crash in March 2020, and the timing of Prime Minister Abe’s resignation. Since they seem to match so well, I understand why people might want to believe what Ling Kokubun says.

But when you listen to Ling Kokubun’s story in detail, something seems off. He claims he was born in 2034 and studied architecture in the Department of Engineering at Tokyo National University, and that he came via a spacetime transfer device in December 2019. There’s nowhere any scientific basis for it. And yet, when this person talks about crypto investment, his statements suddenly become very specific.

According to Ling Kokubun, in early 2020 he bought about 1,400 Ethereum tokens in bulk, put them into a hardware wallet, and buried them in the yard of his parents’ house. As for why he chose Ethereum instead of Bitcoin, he says it’s because the ecosystem has more room for applications. On the other hand, regarding Bitcoin, he talks about the situation in 2058 and says that “you can only sell, and you can’t buy.” In other words, it seems that in the era when Bitcoin reaches 780 million yen (about $4.94 million), there will be no new way to purchase it.

Honestly, it’s hard to judge whether Ling Kokubun’s past predictions are truly “spot-on,” or whether they’re just interpretations added afterward. Predictions about an economic slowdown or forecasts of political change might hit the mark to some extent if you infer them from the information and rumors at the time. There’s also the possibility that he’s using vague insinuations to attract users’ interest.

Still, it’s true that thanks to Ling Kokubun’s story spreading, there’s been renewed discussion about the long-term potential of Bitcoin and Ethereum. But in the world of investing, don’t you think it matters far more to calmly evaluate your own risk tolerance than to rely on “future person” prophecies? Since 2024 and beyond, the prices of crypto assets have been greatly affected by things like U.S. elections and the introduction of ETFs, so it’s important not to get swept away by hype and to hold your own judgment.

In the end, no one knows whether Ling Kokubun is a genuine time traveler or a clever media strategy. It’s fine to enjoy it as an interesting story, but investment decisions are your own responsibility. The only thing you can do is watch market movements and real-world developments to see how the future turns out.
