Junzaburo, also known as JB, has almost two decades of experience as a bengoshi (Japanese-qualified attorney), mainly on M&A, joint ventures, private equity and venture capital investments, general corporate and commercial transactions and IPOs.

Before joining EY, he was a partner at a major global law firm for 10 years. Dual-qualified in Japan and the US, he understands and bridges the gaps that arise from different jurisdictions and cultures.

JB was named a leading individual in the corporate M&A field in Japan by The Legal 500, an international ranking agency for lawyers.

He earned an LLM from New York University, a diploma in Law from The Legal Training and Research Institute of Japan and a LLB from Keio University.

How Junzaburo is building a better working world

“Almost all of my work is cross-border in nature, while every legal system is inherently domestic. My mission is to bridge the gaps across various legal systems and cultures, wherever clients have transactions, projects or problems. I believe that lays the foundation for a better working world for all concerned.”
