Mototsugu Shiraki is the founder of Whitetree Consulting, an independent advisory firm focused on decision architecture, AI governance, and organizational design.

He began his career in the financial industry, where he spent decades working across banking operations, financial control, risk management, and large-scale system transformation. Through this experience, he developed a deep understanding of how complex organizations make decisions—and where those decisions fail.

Throughout his career, he was consistently engaged in situations where traditional frameworks were insufficient:
undefined business rules, fragmented processes, misaligned accountability, and gaps between policy and execution. These experiences led him to a central question:

Why do organizations struggle to share meaning, even when they share data and systems?

To address this, he developed a structural approach to decision-making that captures not only outcomes, but also the underlying intent, boundaries, and rationale behind each decision. This approach forms the foundation of his current work in decision architecture and AI governance.

Shiraki’s work focuses on designing structures that enable:

・Traceable and accountable decision-making
・Integration of human judgment and AI systems
・Preservation and reuse of organizational knowledge
・Alignment across departments, domains, and jurisdictions

He is particularly interested in the governance challenges emerging in the age of generative AI, including semantic ambiguity, boundary definition, and accountability across complex systems.

He is also the author of Beyond The Goal, a conceptual and narrative work exploring organizational transformation, meaning-sharing, and governance in modern enterprises.

Based in Tokyo, Shiraki continues to develop and advocate for practical, implementation-oriented frameworks that address structural challenges in organizations and institutions.
