Shares of Japan’s Metaplanet soared 18.38% on Monday, closing at 966 JPY on the Tokyo Stock Exchange, as investors sought safe-haven assets amid Japan’s worsening debt crisis. The company, often seen as a Bitcoin proxy, has benefitted from heightened demand as Japan’s 30-year government bond yields have surged 100 basis points to a record 3.20% in just 45 days, reflecting intensifying fiscal concerns.
This dramatic bond market shift has resulted in over $500 billion in value losses for 40-year Japanese Government Bonds, exposing deep cracks in the financial system’s stability. Amid this backdrop, investors are increasingly turning to Metaplanet’s Bitcoin-backed stock for refuge.
Rapid Growth and Investor Confidence
Metaplanet has witnessed a staggering 180% surge over the past month, fueled by aggressive Bitcoin acquisitions that echo the strategy employed by MicroStrategy (MSTR) in the U.S. The stock now trades across major global markets including Japan, Germany, and the United States, with trading hours often exceeding 20 hours a day.
- CEO Simon Gerovich confirmed that Metaplanet was the most purchased stock last week through NISA accounts at SBI Securities, Japan’s largest online brokerage.
- Investors are using NISA tax-free investment accounts to gain indirect Bitcoin exposure through Metaplanet.
While some analysts have voiced concerns about the firm’s soaring valuation, Metaplanet’s Bitcoin strategist Dylan LeClair dismissed these fears. He highlighted the company’s BTC rating of 69.24x and its robust Bitcoin Net Asset Value (BTC NAV), which remains significantly over-collateralized even if Bitcoin’s price drops to $2,000.
This financial strength positions Metaplanet as a lower-risk avenue for Bitcoin exposure, offering a buffer against cryptocurrency market volatility while riding the broader Bitcoin price trajectory.

Japan’s Fiscal Crisis Sparks Investor Shift
Japan’s debt-to-GDP ratio has surged past 260%, nearly double that of the U.S. and among the highest globally. Last week, Prime Minister Fumio Kishida referred to the debt situation as “worse than Greece”, underscoring the urgency of Japan’s fiscal challenges.
- Bond auctions have failed to attract sufficient demand, adding to market anxiety.
- A ¥900 billion ($6.5 billion) emergency relief package has been announced to counteract the impact of proposed U.S. tariffs, injecting additional liquidity.
As fiscal instability grips Japan, investors are increasingly seeking refuge in Bitcoin-backed equities like Metaplanet, which combine exposure to digital assets with reduced direct crypto risks. This dynamic suggests Metaplanet’s share price may continue its upward momentum if the crisis deepens.
