A company called Bitcoin Japan just raised roughly $60 million. It plans to spend about $4 million of that on Bitcoin. The rest goes to private equity, rare-earth mining, and robotics.
That’s a 7% allocation to the asset in its own name, which is a bit like opening a pizzeria and dedicating one shelf to frozen pies while the rest of the building houses a car wash.
The deal and the dilution problem
Bitcoin Japan Corporation, listed on the Tokyo Stock Exchange under ticker 8105, announced on July 17 that it had secured approximately ¥9.7 billion, or nearly $60 million, through the issuance of unsecured convertible bonds and stock acquisition rights. The sole subscriber is EVO Fund, a Cayman Islands-based entity with a track record of backing Bitcoin accumulation strategies in public markets.
Of the total haul, roughly ¥662 million (about $4 million) is earmarked for the company’s inaugural Bitcoin purchase. The company currently holds zero Bitcoin. This would be its first.
The bulk of the capital is headed toward private equity investments, rare-earth mining operations, and robotics ventures.
The fundraising mechanism itself is what spooked investors. Convertible bonds and stock acquisition rights are instruments that can be converted into new shares. When a company issues a lot of them relative to its existing share count, it dilutes the ownership stake of current shareholders.
In this case, the estimated dilution rate sits between 95% and 110%. Existing shareholders could see their ownership stake cut roughly in half, or worse. The stock dropped after the disclosure.
From textile trading to Bitcoin treasury
Bitcoin Japan Corporation wasn’t always called Bitcoin Japan. The company formerly operated as Marusho Hotta Co., Ltd., with origins tracing back to 1861 as a textiles and apparel business. The rebrand happened in November 2025 as part of a broader strategic pivot, when the company began positioning itself toward a Bitcoin treasury model.
Bitcoin Japan’s execution of that playbook has been rocky. Prior fundraising attempts reportedly fell through before this deal with EVO Fund materialized. The company arrives at its first Bitcoin purchase with no existing holdings and a name that has been promising something it hadn’t yet delivered.
EVO Fund’s involvement is notable. The Cayman-based fund has participated in similar capital raises for companies pursuing Bitcoin accumulation strategies, making it something of a repeat player in this niche corner of the market.
What this means for investors
A company named Bitcoin Japan is directing 93% of its fresh capital toward things that have nothing to do with Bitcoin. The 7% allocation, roughly $4 million, is a rounding error compared to the treasuries being built by firms like Strategy, which holds tens of billions of dollars in Bitcoin.
The dilution risk is the more immediate concern. A 95% to 110% potential dilution rate is extreme by any standard. For context, dilution in the 20% to 30% range already raises eyebrows among institutional investors. Nearly doubling the share count means the company’s per-share value needs to roughly double just for existing shareholders to break even on paper.
