Making Japanese legal complexity actionable for global business.
日本の法務・規制の複雑さを、海外の企業でも実務で使える形に整理してお伝えします。
I am a Japan-based in-house legal professional with more than 15 years of experience across three corporate legal departments, including a foreign-affiliated energy and infrastructure business.
My work covers commercial contracts, cross-border transactions, regulatory compliance, M&A, dispute management, corporate governance and legal operations.
Through Legal GPT and LegalOS, I translate Japanese legal developments and practical legal experience into structured workflows, decision frameworks and digital tools for legal and business teams.
Legal judgment from inside the business.
事業の内側からの法務判断
My practice sits inside the business, not outside it. Across three corporate legal departments — including a foreign-affiliated energy and infrastructure operator — I have worked at the intersection of Japanese law, commercial decision-making and day-to-day operations.
That experience spans commercial contracts, cross-border transactions, regulatory compliance, M&A, dispute management and corporate governance. Through Legal GPT and LegalOS, I turn it into structured workflows, decision frameworks and digital tools that legal and business teams can actually use.
外資系を含む３社の法務部門で、契約・M&A・紛争・規制対応までを担当してきました。その経験を、Legal GPT と LegalOS を通じて実務で使える形に整理しています。
