Metaplanet, listed on the Tokyo Stock Exchange under ticker 3350, has risen from relative obscurity to rank 33rd among roughly 4,000 Japanese equities by daily value traded. The company’s shift toward accumulating Bitcoin, which accelerated through 2024, has effectively turned it into a Bitcoin holding vehicle for public-market investors. It has ranked as high as 29th on particularly active days and recorded about ¥21.9 billion, or approximately $142 million, in trading during one November 2024 session. Metaplanet has also frequently led the TSE Standard Market in trading volume and value, at times exceeding the daily turnover of Toyota and Sony. In June 2026, monthly trading volume reached ¥1.87 trillion. Shares recently traded between ¥300 and ¥350, implying a market capitalization of roughly ¥380 billion to ¥450 billion, while multi-year returns at one point exceeded 1,000%. The company holds an estimated 35,000 to 43,000 BTC, making it Japan’s largest corporate Bitcoin treasury holder. CEO Simon Gerovich has regularly highlighted the strategy and trading milestones in public communications. The stock offers Japanese investors Bitcoin exposure through standard brokerage accounts and tax-advantaged NISA accounts, Japan’s equivalent of a Roth IRA, unlike direct Bitcoin purchases, which involve separate exchanges, tax treatment and regulatory arrangements.
