When Arthur Murray International featured Susan Mitsui and her husband Michael in a segment for its Lifestyle Series, it identified them as franchisees across five studio locations in Japan: Osaka, Tokyo, Kobe, Yokohama, and Nagoya. That description captures only part of what the work involved.
Running multiple studio locations across Japanese cities since 2008 has meant managing instructor teams, designing and selling programs, building client retention, overseeing profitability, and sustaining organizations across cultural and geographic boundaries. What that tenure produced, beyond a functioning multi-city operation, was a specific conviction about where physical discipline and business leadership intersect. That conviction is the foundation of Adder Industries, the company Mitsui co-founded with Michael to share that discovery with a wider audience.
Three Decades, Several Disciplines
The career behind Adder Industries extends well beyond the studio work. Mitsui’s professional account places more than 25 years of experience across dance, business ownership, leadership development, international event management, and coaching across Japan, Canada, the United States, Taiwan, and Australia. Before the Japan operation, her professional record describes a competitive career in ballroom dance spanning approximately a decade, which she characterizes as building the structural discipline and execution habits that have carried through everything since.
She has also worked internationally as an event director and traveling coach, supporting dance organizations across Asia and Australia, and has taken on senior evaluation roles within the competitive dance world. Her professional record credits her with contributing to the production, casting, and choreography of Flash Band Beat, a 2015 live entertainment show at Universal Studios Japan. That production received a Brass Ring Award from the International Association of Amusement Parks and Attractions, the industry body that recognizes excellence across theme park and attraction entertainment globally. The award went to Universal Studios Japan for the production overall; Mitsui’s contribution was one part of a larger creative collaboration. She and Michael currently continue to operate their Arthur Murray locations in Japan while building out Adder Industries from their base in Kobe.
Two Pillars, Two Tools
Adder Industries is organized around two core pillars. The first is Leadership and Growth: one-on-one and small-group coaching for entrepreneurs, executives, and teams, built on what the company describes as the integration of embodied intelligence with strategic thinking. The premise is that how a leader physically occupies a space communicates independently of words, and that physical and professional presence develop from the same source.
The second pillar is Health and Wellness. Drawing directly on Mitsui’s background in movement and performance, this side of the business addresses what the company describes as the tendency to treat wellbeing, leadership, and purpose as disconnected concerns. The work includes movement-based practices, mindset frameworks, and community-oriented programming. Adder Industries approaches these not as standalone wellness offerings but as a foundation that connects to and reinforces the leadership work.
Powering both pillars are two supporting capabilities. The first is AI Systems and Media: custom brand imagery, cinematic content, and visual identities built using AI-driven production tools. A leader’s brand presence, in Mitsui’s framework, is an extension of personal presence, and both draw on the same underlying qualities the core programs develop. The second is Digital Programs and Frameworks: downloadable playbooks and guides covering content strategy, brand development, leadership, and personal mastery, including the company’s proprietary LIFE Method (Lead, Inspire, Flourish, Empower). These are designed, by the company’s own account, for direct practical application rather than theoretical instruction.
A Company Still Taking Shape
Adder Industries is early in its development, and the company says so plainly. Its work portfolio acknowledges that detailed case studies are being assembled as the client base grows, and the current emphasis is on building the framework clearly before the projects fully demonstrate it. That transparency is consistent with how Mitsui frames the work across the company’s materials: as a practice and a discovery, not a product with a guaranteed return.
The core argument behind Adder Industries, that physical discipline and business discipline share the same foundation, is one that depends on a particular kind of career to carry with credibility. That argument reads differently when it comes from someone who built and ran a multi-city franchise operation in Japan, who contributed to live entertainment at one of Japan’s largest theme parks, and who spent a decade competing at a professional level before any of it. Mitsui’s career is that kind of career. Adder Industries is what she is doing with it.
