What is the cryptocurrency investment scenario predicted by Rei Kokubu, the 'Future Person' from 2058?

Online, the figure known as “Japan’s strongest future person” Rie Kokubun is making waves. Claiming to have arrived in modern society via a spacetime transfer device from 2058, her series of statements and behaviors have sparked heated debates among investors and internet users. While her story is inherently fantastical, the fact that multiple of her past predictions appear to align with reality has contributed to her following.

Her rise to prominence began with bold statements made between 2019 and early 2020. At that time, she reportedly predicted Japan would win 27 gold medals at the Tokyo Olympics, forecasted a major crash of the Nikkei 225 in March 2020, and even predicted Prime Minister Shinzo Abe’s resignation in September 2020. The realization of these predictions in line with actual events led some supporters to regard her as “someone with a secret source of information beyond time.”

The Mysterious “Future Person” Background: From the World of 2058

Rie Kokubun claims her background includes enrollment in the Department of Architecture at Tokyo National University in 2034. While her claims of time travel lack scientific basis, her series of posts on X (formerly Twitter) quickly made her a social media sensation.

Her setting as someone who came from the future of 2058 is not just a gimmick; it remains consistent even in her subsequent investment advice. The cryptocurrency strategies she presents are not mere whims but are constructed from the perspective of “someone who knows the world 30 years from now.”

The Massive Purchase of 1,400 Ethereum and Its Strategic Context

The most notable aspect is her investment strategy. She states that between December 2019 and early 2020, she used her father’s account to purchase approximately 1,400 Ethereum. These tokens are stored in a hardware wallet and buried in her parents’ yard, with plans to excavate them in 2058.

What’s intriguing is why she chose Ethereum over Bitcoin. According to her explanation, it’s not because she has given up on Bitcoin, but because she believes the Ethereum ecosystem offers more application opportunities and greater potential for growth. This choice appears to have some foresight, especially considering Ethereum’s planned network upgrades and DeFi expansion after 2024.

Is “Selling Only” the Future for Bitcoin? Enigmatic Predictions

Conversely, her predictions regarding Bitcoin are more complex. She claims that by 2058, Bitcoin will have reached an astonishingly high price, but “you will only be able to sell, and cannot buy.”

What does this imply? According to her, if Bitcoin hits 7.8 billion yen (approximately $4.94 million), new means of acquiring Bitcoin will be severely limited, or the liquidity and trading characteristics of Bitcoin will fundamentally change. Given that the current BTC price (as of January 2026) is around $83,070, this prediction entails about a 60-fold increase, suggesting a scenario where the entire market structure could drastically change.

Supporters find this exciting, interpreting it as “there’s still room to buy Bitcoin now” and “a perfect opportunity for long-term holding strategies.”

Were Past Predictions Truly “Divinely Accurate”? Verification and Doubts

Let’s critically examine some of Kokubun Rie’s successful predictions. Her forecasts about the Tokyo Olympics medals, early warnings about COVID-19, and the timing of Abe Shinzo’s resignation all show a certain degree of accuracy. However, many researchers and critics question whether these “hits” are truly mystical or just coincidental.

Some point out that her economic and political predictions are likely based on current trends and rumors rather than clairvoyance. There are also criticisms that her vague language, post-hoc adjustments, and ambiguous expressions may be designed to give an impression of accuracy.

Furthermore, mainstream science and media remain highly skeptical of the concept of time travel. In Japan, her statements are often seen as vague and possibly using ambiguous hints to attract user interest.

As of 2026: The Reality of Bitcoin and Ethereum

To evaluate her predictions, let’s look at the actual cryptocurrency market as of January 2026:

• Bitcoin (BTC): $83,070
• Ethereum (ETH): $2,750

These figures highlight how far the market still is from her predicted “impossible-to-sell high” in 2058. To reach $4.94 million per Bitcoin, a roughly 60-fold increase from current levels, is a significant leap—possible in theory, but perhaps more in the realm of science fiction.

What Investors Should Know: Differentiating Future Predictions from Market Reality

Regardless of the truth, Kokubun Rie’s statements are fueling active discussions among crypto investors. Some are tempted to follow her “2030s future scenarios,” but experts advise caution.

When making investment decisions, keep in mind:

• Assess your risk tolerance objectively: Investments based on future predictions should align with your financial situation.
• Avoid panic selling: Phrases like “you can only sell” may trigger speculative behavior and panic selling.
• Focus on market fundamentals: Post-2024, Bitcoin and Ethereum prices are influenced by real-world factors such as U.S. political developments and ETF approvals.

Investors should remain calm amid hype and avoid blind following or excessive panic.

The Mystery of 2058 Will Only Be Solved in the Future: Final Evaluation

Ultimately, the true nature of Kokubun Rie as a “future person” and the authenticity of her predictions remain shrouded in mystery. Her presence may be more of an intriguing media phenomenon for the crypto market. For some believers, she functions as a “prophet receiving divine revelation.”

However, whether or not one believes in future information, prudent investing requires careful judgment and risk management. Whether time travelers truly exist or it’s just a clever act, the answer will only be known in 2058. Until then, investors should monitor market developments and trust their own judgment.
