Profile

Tomoko Yoshimura

Tax Accountant / Entrepreneur / Cash-Good Life Advocate CEO, Cash Good Life Research Institute, Inc.

“To live freely, it’s essential not to be chased by money.”

With this belief, I support individuals and business owners in building both financial discipline and the courage to take on new challenges — through what I call a cash-good life.

With 17 years in the tax accounting industry, I’ve supported over 200 companies and advised more than 2,000 entrepreneurs and executives, from listed enterprises to sole proprietors.

I provide tax advisory, cash management, and cash-rich business planning, along with an AI-based school for improving profitability and efficiency.

As an entrepreneur, I also run MONEY AI, an AI-powered business school, and operate SOCIAL GOOD GALLERY, supporting creators in balancing creativity with financial independence.

In addition, I support international tax strategies through Nexus Tax Partners, working with experts in Japan and Spain.
