A Japanese company that used to run budget hotels now holds more Bitcoin than most countries' reserves. In two years, Metaplanet poured over ¥600 billion into BTC, taking it to world No. 3 among publicly traded corporate holders. Here is how a Tokyo-listed firm pulled it off, and why Japan's financial landscape made it possible.

Metaplanet Crosses the 40,000 BTC Milestone

On April 2, 2026, Tokyo-listed Metaplanet Inc. (TSE: 3350) announced it had acquired 5,075 BTC during the first quarter of 2026, bringing its total holdings to 40,177 BTC, worth approximately $2.6 billion at current prices.

According to Bitcoin Treasuries data, this purchase pushed the company past MARA Holdings to claim third place globally among publicly traded corporate Bitcoin holders.

Here are the key numbers from Q1 2026:

  • BTC acquired in Q1: 5,075 BTC
  • Q1 total spend: Approximately $400 million (¥63.6 billion)
  • Q1 average price: About $78,000 (¥12.54 million) per BTC
  • Net cost after options income: About $75,000 (¥11.95 million) per BTC
  • Total BTC held: 40,177 BTC
  • Cumulative investment: Approximately $3.9 billion (¥623.3 billion)
  • Overall average cost: About $97,000 (¥15.51 million) per BTC

The company kept going. On July 2, 2026, Metaplanet reported buying another 2,823 BTC in the second quarter for ¥35.886 billion, at an average of ¥12,712,055 per coin. That brought total holdings to 43,000 BTC, cumulative spend to ¥659.256 billion, and the overall average cost to ¥15,331,542. Bitcoin Income Business revenue was ¥1.747 billion in Q2, ¥4.717 billion for the first half of 2026, and roughly ¥11.4 billion over the trailing twelve months.

A standout detail is Metaplanet's "Bitcoin Income Business." By selling options contracts backed by its BTC holdings, the company generated $19.8 million (¥2.97 billion) in revenue during Q1 alone. This income effectively reduces the net purchase cost per Bitcoin, a strategy that sets Metaplanet apart from most corporate BTC accumulators.

The Global Corporate Bitcoin Leaderboard

As of April 2026, the top publicly traded companies by Bitcoin holdings look like this:

  1. Strategy (formerly MicroStrategy): ~762,099 BTC (~$58 billion)
  2. Twenty One Capital: ~43,514 BTC
  3. Metaplanet: 40,177 BTC (~$2.6 billion)
  4. Bitcoin Standard Treasury Corp: ~30,021 BTC
  5. Bullish: ~24,300 BTC

The gap between Strategy and everyone else remains enormous, Strategy holds roughly 19 times more BTC than Metaplanet. But Metaplanet's ascent from its first purchase in April 2024 to over 40,000 BTC in two years is remarkable by any measure. As of July 2026 it still sits third, though the gap to Twenty One Capital (43,514 BTC) has narrowed to 514 coins.

Metaplanet's rise also partly reflects MARA Holdings' retreat. The US-based mining company sold about 15,133 BTC in March 2026, using the proceeds to buy back approximately $1 billion in convertible notes. That sell-off allowed Metaplanet to leapfrog MARA in the rankings.

The "Japan's MicroStrategy" Strategy

Metaplanet wasn't always a Bitcoin company. Originally called Red Planet Japan, it operated budget hotels across Japan. In February 2023, the company rebranded and pivoted to making Bitcoin its core treasury asset.

CEO Simon Gerovich has laid out an ambitious vision: transforming "Japan's multi-trillion-yen bond capital market into a Bitcoin accumulation engine." The company's roadmap, dubbed the "555 Million Plan", targets 100,000 BTC by the end of 2026 and 210,000 BTC by the end of 2027.

To fund its purchases, Metaplanet has tapped diverse capital sources beyond ordinary share issuances. In November 2025, it launched a perpetual preferred stock called "MERCURY," raising approximately $142 million (¥21.2 billion), with about $100 million earmarked for BTC purchases.

The core thesis behind this strategy centers on hedging against structural weakness in the Japanese yen. Japan faces persistent currency depreciation pressure, one of the world's highest government debt-to-GDP ratios, and prolonged low interest rates. Metaplanet positions Bitcoin as "digital gold", a store of value outside the Japanese monetary system.

How Metaplanet Compares to Strategy

While often called "Japan's MicroStrategy," the two companies differ in several important ways.

Scale: Strategy has committed approximately $58 billion to accumulate over 762,000 BTC, about 3.4% of Bitcoin's total fixed supply of 21 million coins. Under its "42/42 Plan," it aims to deploy another $84 billion by 2027. Metaplanet's $3.9 billion and 40,000 BTC represent roughly one-twentieth of Strategy's position.

Business transformation: Both companies have effectively abandoned their original businesses. Strategy was once an enterprise software firm; Metaplanet was a hotel operator. Today, Bitcoin-related revenue accounts for about 91% of Metaplanet's total income.

Revenue model: Here's where Metaplanet diverges. Its Bitcoin Income Business, generating steady cash flow from options premiums on its BTC holdings, gives it a revenue stream that Strategy doesn't have. Strategy relies primarily on stock and debt issuance to fund purchases, while Metaplanet supplements capital raising with operational income from its BTC stack.

Tax environment: This is the most significant difference. In the US, corporate capital gains are taxed at a federal rate of 21%, and the accounting treatment for Bitcoin has become clearer following FASB's fair value accounting rule change. In Japan, corporations holding crypto assets have faced mark-to-market taxation at fiscal year-end, potentially triggering tax liability on unrealized gains, a major headwind for any company trying to accumulate Bitcoin.

Japan's Crypto Tax Revolution, A Game Changer?

The biggest external factor shaping Metaplanet's future may be Japan's ongoing crypto tax reform.

In December 2025, Japan's ruling coalition published its 2026 tax reform outline, which included a landmark shift: crypto gains would move from comprehensive taxation (where rates can reach up to 55%) to a flat 20.315% separate filing tax, the same rate applied to stocks and mutual funds.

Key features of the reform:

  • Applies to spot trading, derivatives, and crypto ETFs involving "designated crypto assets"
  • Tax rate: 15% income tax + 5% resident tax (approximately 20%)
  • Losses can be carried forward for up to 3 years
  • Contingent on passage of amendments to the Financial Instruments and Exchange Act (FIEA)

There's an important caveat: this reform targets individual investors, not corporations directly. Corporate taxation of crypto holdings remains a separate policy discussion. While a 2023 reform exempted companies from mark-to-market taxation on tokens they themselves issued, third-party tokens like Bitcoin purchased on the open market may still face year-end valuation challenges.

The FIEA amendment bill went to the ordinary Diet session in 2026, reclassifying crypto assets from a "means of payment" under the Payment Services Act into a "financial instrument." The new tax treatment takes effect on January 1 of the year following the amended law's entry into force, which points to January 2028 at the earliest.

Risks That Can't Be Ignored

Metaplanet's strategy carries substantial risks that investors should weigh carefully.

Price volatility: As of February 2026, Metaplanet was sitting on approximately 39% in unrealized losses due to Bitcoin's decline from its highs. Bitcoin's 52-week range spans roughly $60,000 to $126,000. The coin was near $67,000 in April 2026 and, after dipping below $60,000, recovered to around $64,000 in early July. Those losses show up in the accounts: for Q1 of the fiscal year ending December 2026, operating profit rose 282.5% year on year while a Bitcoin writedown produced a net loss of ¥114.4 billion.

Stock price correlation: Metaplanet's stock price has a reported correlation coefficient of about 0.9 with Bitcoin's price, making it function essentially as a leveraged Bitcoin proxy. The stock has tumbled from its February 2025 high to around ¥308 as of early April 2026. It hit a year-to-date low of ¥192 on July 1, 2026, and traded around ¥248 on July 13.

Dilution: Aggressive equity issuance to fund BTC purchases dilutes existing shareholders. While the shareholder base has grown from 10,900 in December 2023 to 128,100 by June 2025, the company has also sought approval to expand its authorized share count significantly.

Regulatory uncertainty: Bloomberg reported in November 2025 that the Japan Exchange Group (JPX) was weighing tighter rules for crypto treasury companies. Any change to listing standards would hit the business model directly.

The Ranking Went Up. The Losses Stayed.

A place on the holdings leaderboard is not a measure of whether the strategy works. In the same quarter Metaplanet climbed to third, it booked a ¥114.4 billion net loss. Buying more always moves you up the table, but with an average cost of ¥15,331,542 per coin, every day the yen price of Bitcoin sits below that number adds to the unrealized loss. The company announced its latest purchase the day after its stock hit a year-to-date low, and the stock bounced. That sequence says a lot about what is actually being sold here.
