Leadership in Japan

Koji Shiota
Chief Operating Officer,
ATD Solution, Japan  

ATD Solution Japan is led by Koji Shiota, who brings extensive experience in enterprise architecture, digital transformation, and business process optimisation. His deep understanding of Japan’s unique business landscape enables ATD Solution Japan to deliver solutions that blend global expertise with local relevance, helping organisations maximise the impact of their enterprise architecture initiatives.

“Our mission in Japan is to empower organisations to achieve strategic business outcomes by effectively aligning IT and business strategies,” said Koji Shiota. “We strive to equip professionals and organisations with the tools, knowledge, and frameworks they need to thrive in today’s rapidly evolving business environment.”  

Why Japan?

Japan is experiencing significant digital and organisational transformation. Companies are increasingly challenged to innovate, adopt new technologies, and improve operational efficiency. Enterprise Architecture is becoming a critical enabler for organisations seeking to:  

• Align IT with Business Goals: Implement industry best practices and recognised framework such as TOGAF® to ensure technology investments drive business value.


• Optimise Processes and Workflows: Streamline operations to improve efficiency, reduce redundancy, and enable faster decision-making.


• Develop Professional Talent: Build a workforce capable of sustaining enterprise architecture initiatives and leading transformation projects.


• Enhance Organisational Agility: Create flexible enterprise architectures that can quickly adapt to market shifts and technological disruption.

With its expansion into Japan, ATD Solution will offer tailored enterprise architecture consulting services, providing Japanese organisations with practical, actionable solutions while also upskilling local professionals through internationally recognised certification programmes.  

Supporting the Local Enterprise Architecture Community

As part of its expansion, ATD Solution is proud to support the IASA Japan Annual Enterprise Architecture Conference 2025, taking place on 29–30 October in Tokyo. The conference will bring together thought leaders, industry experts, and practitioners to explore the latest trends, frameworks, and best practices in enterprise and business architecture.

Participation in this conference reflects ATD Solution’s commitment to contributing to the professional EA community in Japan while strengthening ties with local organisations pursuing digital transformation initiatives.

“Our participation in IASA Japan 2025 reflects our commitment to the professional community in Japan,” said Koji Shiota. “We look forward to collaborating with organisations, transformation leaders, and peers to advance the adoption of enterprise architecture and promote continuous professional development.”
