From foundation to disciplined deployment.
Bitcoin Japan Corporation (formerly Marusho Hotta, founded 1861) is a Tokyo Stock Exchange listed company building a platform for strategic exposure to AI, Bitcoin, and the infrastructure behind the next-generation technology cycle.
We have put an institutional foundation in place — strengthened governance, an international corporate structure, and a global leadership team built to operate at world-class standards.
We are focused on disciplined capital deployment — every decision measured by long-term intrinsic value per share.
Investing across the AI value chain.
Artificial intelligence is not a single market — it is a value chain that runs from resource to agent. We concentrate where capital efficiency, growth, and Japan's edge align.
Critical Minerals & Energy
Rare earths and power — the scarce upstream inputs everything depends on. This is where we are pursuing a direct, upstream position.
Frontier AI
The model layer: the highest-value, fastest-moving and most capital-intensive part of the chain. We invest pre-IPO in foundation-model platforms and the infrastructure around them.
Physical AI & Robotics
Humanoids and embodied AI — early, and where Japan has a manufacturing edge. We own and operate here through our Robotics-as-a-Service business.
Applied & Agentic AI
Consumer and vertical apps, autonomous agents, and the programmable payment rails they transact on — where we both invest and build rails.
Where we deploy capital.
Rare Earths
The Materials Behind AI
China refines roughly 92% of NdPr and 98–99% of heavy rare earths, while Japan imports nearly all of its supply. With prices climbing and a G7 critical-minerals alliance forming, rare earths are a strategic priority — and we are pursuing an upstream position in this part of the chain.
Robotics & Physical AI
Preparing for the Age of Humanoids
Humanoid and embodied AI is early, and Japan — facing a structural labor shortage — is a natural deployment market. Our operating business is Robotics-as-a-Service (RaaS), and our investment in Figure AI extends that strategy into physical-world automation.
Frontier AI
Access to the Next Generation of AI Companies
Frontier capability is created by a small set of companies. Our global relationships provide proprietary private-market and pre-IPO access — demonstrated by completed positions in SpaceX and Figure AI through our cross-border investment platform.
Bitcoin & Digital Assets
Digital Assets and Future Financial Infrastructure
Bitcoin is the only globally liquid monetary asset with a permanently fixed supply of 21 million. We hold it as long-term strategic treasury capital and are positioned for the convergence of AI and blockchain as autonomous agents adopt programmable money.
Why Bitcoin Japan.
TSE-Listed Access
A Tokyo Stock Exchange listing gives investors regulated, transparent access to AI and the broader digital-asset economy.
International Structure
Operational Delaware, Cayman, and Dubai vehicles and a cross-border board let us originate and access global opportunities.
AI & Robotics Platform
AI investments paired with a Robotics-as-a-Service operating anchor place us directly inside the AI value chain.
