Metaplanet reports soaring Bitcoin adoption in Japan, 1 in 600 are shareholders
The Tokyo-listed Bitcoin treasury firm has grown its domestic shareholder base by 66%, now claiming roughly 0.2% of Japan's population as investors.
Think of a mid-sized Japanese hotel company pivoting to become one of the world’s largest corporate Bitcoin holders. That’s Metaplanet in a nutshell.
Metaplanet (TSE: 3350) now counts approximately 212,571 domestic shareholders, a figure that works out to roughly 0.2% of Japan’s population. That shareholder base grew 66% in recent months.
From 10,000 to 212,000 shareholders in two years
When Metaplanet launched its Bitcoin treasury strategy in April 2024, the company had around 10,000 shareholders. It blew past 64,000 on the way to today’s 212,571 figure. The company’s long-term target is exceeding one million shareholders.
Metaplanet is essentially trying to redirect capital toward Bitcoin through the comfort of a traditional stock listing. Strategy, formerly MicroStrategy, pioneered this model in the US.
The company now holds 40,177 BTC, making it Asia’s largest corporate Bitcoin holder and the third-largest among public companies globally, behind Strategy and Twenty One Capital. It purchased 5,075 BTC in Q1 2026 alone as part of its ongoing accumulation push.
Building the infrastructure for Bitcoin yield products
In June 2026, the company acquired Siiibo Securities for approximately $13 million. The deal gives Metaplanet a Type I financial instruments business license, which is the regulatory key needed to sell Bitcoin-linked yield products directly to Japanese investors.
The company is also pursuing a $5.4 billion equity facility, denominated at roughly 770.9 billion yen. That capital is earmarked for buying more Bitcoin. Metaplanet’s stated ambition is to accumulate up to 210,000 BTC in total, which represents 1% of Bitcoin’s total 21 million supply cap.
What this means for investors
The dilution risk is a key consideration. A $5.4 billion equity facility means Metaplanet will be issuing a lot of new shares. If Bitcoin’s price rises fast enough, the BTC-per-share metric improves. If Bitcoin stalls or drops, shareholders absorb dilution without the offsetting gain.
If Metaplanet successfully launches Bitcoin yield products for Japanese retail investors via the Siiibo Securities acquisition, it creates a revenue stream beyond simple price appreciation, potentially differentiating it from pure treasury plays.
