From championship dance and entrepreneurship to coaching, leadership, wellness and international business, our work is built on decades of real-world experience. We turn that experience into practical systems that help people and businesses grow, perform and thrive. Built to develop people. Built to create opportunity.
From performance to impact
Championship titles. Businesses built across markets.
Decades of coaching, teaching and leadership. What began in performance evolved into a broader understanding of how people grow, lead, adapt and achieve results, and became the foundation for Adder Industries.
The story
It started on the floor, not in a boardroom. Long before Adder Industries, Susan and Michael Mitsui built careers in championship dance, performance, and coaching, then co-owned and operated five Arthur Murray studios across Japan.
That work taught them something simple: the discipline that wins on stage is the same discipline that grows a business, a brand, and a life. Presence is trained. Growth is practical. Health has to hold in daily life.
Adder Industries exists to help individuals, creators, entrepreneurs, executives, and businesses command their presence, scale their impact, and build a life that lasts. Build capability. Expand possibility.
“Where Motion Meets Mastery is not just a tagline. It is the philosophy that guides everything we create.”

Susan Mitsui is a 5-Time Canadian Dance Champion, World Mambo Finalist, Arthur Murray International Latin Champion, and IAAPA Award-winning creative contributor. A former professional performer and film cast member (Shall We Dance?, Miramax 2004), she spent over a decade on the competitive circuit before co-owning and operating five Arthur Murray studios across Japan.
Her work has spanned Japan, Canada, the United States, Taiwan, and Australia, as Master Examiner, international event organizer, executive operator, coach, and International School Council Member, at the intersection of elite physical discipline, health and wellness, and serious business leadership.
She is also a founder of Fitness Reimagined, a holistic movement and wellness collaboration.

Our Philosophy
One concept. Added everywhere.
Presence is developed
Real presence is not something you perform. It is something you develop, in the body, in decisions, in relationships, and in how you move through a room.
Performance and wellbeing are interconnected
Energy, health, mindset, relationships, recovery and leadership influence one another. They are not separate problems.
Mastery is a practice
Mastery is not perfection. It is the daily commitment to develop the internal qualities that show up externally as results.
The Through-Line
From performance to possibility
Experience became systems. Systems create impact. Adder Industries turns decades of real performance into practical systems people and organizations can use.
