“Metaplanet ranked 29th out of 4,000 listed companies in Japan by transaction value, beating much larger market rivals such as Itochu and NTT,” Metaplanet CEO Simon Gerovich wrote in a post on X (formerly Twitter).

The company reported a $BTC return of 186.9% between October 1 and November 19, highlighting the profitability of its aggressive Bitcoin accumulation strategy.

On Monday, Metaplanet announced that it had issued a one-year bond worth ¥1.75 billion ($11.3 million), with the funds earmarked for further Bitcoin purchases.

The bond is dated November 17, 2025, underscoring Metaplanet’s commitment to long-term Bitcoin investments.

Metaplanet’s bold moves are in line with the growing institutional interest in Bitcoin, while US-based MicroStrategy remains the largest public institutional holder of Bitcoin with 331,200 $BTC.
