Tokyo Stock Exchange-listed Bitcoin Japan, formerly Hotta Marusho, has approved a Bitcoin treasury business and its first-ever purchase of spot Bitcoin, with an initial investment capped at $1 million, or approximately ¥160 million. The board approved the plan on Sept. 17, and the company announced it on Sept. 18. The acquisition will be executed through BTC JPN Ltd., a wholly owned Cayman Islands subsidiary, with the remittance covering both the Bitcoin purchase price and fees. Part of the funding will come from the ¥1.5 billion raised through convertible bonds issued in July to EVO FUND, a Cayman Islands-based investment fund. Bitcoin Japan plans to hold Bitcoin as a long-term strategic asset and make selective purchases based on market conditions, rather than pursue short-term trading or set volume and revenue KPIs. Under a board-approved risk management framework, it is also considering BTC lending, derivatives, hedging and related product investments after the necessary infrastructure is established. The company changed its name from Hotta Marusho to Bitcoin Japan in 2025 and had held no BTC until this initial purchase. A December 2025 warrant issue did not generate the expected funds because the warrants were not exercised as planned. The move adds Bitcoin to the balance sheet of a Japanese listed company, although the initial size is too small to drive major capital inflows immediately. Bitcoin Japan Corporation is separate from Bitcoin Japan Inc., a Metaplanet subsidiary and the world’s third-largest corporate BTC holder.
