Bitcoin Treasury Firm Metaplanet Joins FTSE Japan Index — Can Its Stock Return to Yearly Highs?

TradingKey – On Monday, August 25, shares of Japanese Bitcoin treasury firm Metaplanet (TSE:3350) rebounded sharply, rising 3.35% to JP¥864, following news of its inclusion in the FTSE Japan Index. While the announcement helped halt the recent downtrend, the upside remains limited for now.

Metaplanet was added to the FTSE Japan Index as part of FTSE Russell’s September 2025 Semi-Annual Review, thanks to its robust second-quarter performance. The company’s stock surged from a Q2 low of JP¥400 to a peak of JP¥1,900, marking its highest price this year. However, by June 30, the stock had pulled back to JP¥1,600, still up 300% from its earlier lows.

As of this writing, Metaplanet holds 18,888 BTC, making it the largest Bitcoin-holding company in Japan and the seventh-largest globally. Its inclusion in the FTSE Japan Index also means automatic entry into the FTSE All-World Index, which could attract passive capital flows from global index-tracking funds.

This structural upgrade boosts visibility among institutional investors and may support further price recovery — provided Bitcoin itself resumes its upward trajectory.Bitcoin has been trading sideways between $110,000 and $125,000 over the past month. Without a clear signal from the Federal Reserve—such as a confirmed rate cut — BTC may struggle to break out, limiting Metaplanet’s upside potential in the near term.
