Metaplanet Climbs into Japan’s Elite Stock Index
Japan’s first Bitcoin treasury company has been upgraded from small-cap to mid-cap in FTSE Russell’s Global Equity Index Series.
The index vendor’s September 2025 Semi-Annual Review announced the upgrade of Metaplanet from an “ineligible IPO” status, which subsequently gives it access to the FTSE Japan Index, a gauge of mid-and large-cap Japanese exchange stocks.
The upgrade also puts Metaplanet on the FTSE All-World Index, which contains a large all-country benchmark of the leading public companies by region.
Why This Matters: Bitcoin Exposure for Passive Investors
Because of the upgrade, Metaplanet will automatically attract capital through index-tracking funds and exchange-traded products (ETPs).
For passive investors holding FTSE Japan or FTSE All-World portfolios, this means indirect exposure to Bitcoin — without ever actually buying BTC.
According to analysts, being included in an index grants access to both institutional and retail investors. “It places Bitcoin further inside the worldwide financial system.”

Metaplanet Outperforms Japan’s Blue Chips
Metaplanet’s rise was based on a stellar Q2 performance that left Japan’s top corporations in the dust:
- Metaplanet stock (2025 YTD): +187%
- TOPIX Core 30 (Toyota, Sony, Nintendo, etc.): +7.2% YTD
The company’s success reflects a surge of confidence in its Bitcoin-first strategy, which it adopted after rebranding from a hotel operator in 2024.
A Bitcoin Treasury Giant in the Making
Metaplanet currently holds 18,888 BTC, making it the seventh-largest publicly traded Bitcoin holder in the world – ahead of Coinbase, Tesla, and Hut 8 Mining. It is also Japan’s largest corporate Bitcoin holder.
CEO Simon Gerovich has expressed an ambitious goal of amassing 210,000 BTC by 2027 – equivalent to 1% of Bitcoin’s 21 million supply cap.
To achieve this, Metaplanet plans to:
- Use its Bitcoin reserves to buy income-generating businesses
- Expand into digital banking and digital asset infrastructure
⚡ Bottom Line
Metaplanet is now a mid-cap FTSE-listed firm, marking a milestone for Bitcoin adoption in traditional finance.
With its rapid growth, audacious treasury plans, and access to global investors, the company is quickly becoming Japan’s MicroStrategy — but with even bigger ambitions.
