Connecting Continents: Megumi Ryoya Played ‘Indispensable Role’ in Exxon-Mitsubishi Hydrogen Deal
Megumi Ryoya saw her future as a corporate lawyer during her senior year of college at Waseda University.
“I met an in‑house counsel at a well‑known Japanese manufacturer who told me that formal legal training and a bar license would significantly broaden what I could do professionally,” Ryoya told The Texas Lawbook. Fifteen years later, Ryoya is senior counsel at global powerhouse Mitsubishi Corporation, where she played a critical role during the past year in developing a joint venture agreement between Mitsubishi and ExxonMobil to develop the world’s largest low-carbon hydrogen project.
Citing her achievements, the Association of Corporate Counsel’s Houston Chapter and The Lawbook are honoring Ryoya with the 2026 Houston Corporate Counsel Award for Senior Counsel of the Year for a Midsized Legal Department. The awards recognize lawyers who have been in-house for two years or less.
