About Thrive Tokyo Co., Ltd.

At Thrive Tokyo Co., Ltd., I, Katheryn Gronauer, equip global professionals in Japan with the leadership mindset and cross-cultural capability they need to perform at their best—no matter the transition or challenge.

As CEO and Lead Facilitator, I bring nearly a decade of experience as a corporate trainer and ICF-certified Executive Coach (PCC), supporting thousands of managers and high-potential leaders across industries since 2016. I am also a TEDx speaker and author.

What Thrive Tokyo Co., Ltd. Stands For

Sustainable performance in Japan requires more than technical skills. It demands three things:

  • Clarity of purpose

  • Cross-cultural insight

  • The confidence to navigate change

When even one of these is missing, talented professionals struggle with alignment, communication, and impact. My programs are designed to close these gaps quickly and effectively.

Why Companies Partner With Thrive Tokyo Co., Ltd.

I founded Thrive Tokyo Co., Ltd. to provide organizations with boutique, high-impact leadership training and coaching delivered in a format that fits the realities of global teams in Japan.

My approach blends practical leadership skills, cultural awareness, and mindset work to help your people show up with confidence, communicate effectively, and lead with greater influence.

Whether through our structured programs or our targeted, plug-and-play training modules, I help your talent move from uncertainty to clarity, and from competent performers to empowered leaders.
