Yanagisawa International Tax Accounting Firm
Representative: Kenji Yanagisawa (Tax Accountant)
Thank you very much for visiting our website.
Since our founding in 2004, our firm has met all of our clients' tax-related needs, both individuals and corporations, ranging from retainer tax accountant services to tax audit support, National Tax Tribunal appeal support, and tax litigation advisory services.
Additionally, we provide comprehensive support tailored to every stage of a company's lifecycle—both domestically and internationally. Based on tax and accounting, our services range from finance to management, including startup support for entrepreneurs, assistance with overseas expansion for small and medium-sized enterprises, support for overseas relocation by owner-executives, and achieving an exit through M&A.
When I think back on how we came to be able to handle such a wide range of requests, I realize that it all comes down to the encounters we've had with our customers.
With a sincere desire to meet our customers' needs, we have grown together with them at every step. This accumulated experience has led to the wide range of support we offer today.
Currently, the Japanese economy faces challenges such as a declining birthrate, an aging population, and a fiscal deficit, and the environment surrounding corporations and individuals is also changing.
However, even amidst such economic conditions, entrepreneurs and startup founders are always full of energy and shining brightly, and there are certainly excellent small and medium-sized enterprises that continue to grow steadily. Furthermore, there are owner-executives and affluent individuals who are achieving their ideal lives by changing their bases for living and economic activities, or through business succession via M&A.
We are committed to our daily work with the goal of becoming a company that brings together words of gratitude and smiles by providing concrete "strategies" backed by advanced expertise and ideas to corporate and individual clients whose drive for growth is relentless, and by delivering results.
We will continue to do our absolute best to ensure that all of our clients are satisfied and reward us with their smiles and words of gratitude.
Please feel free to consult with us.
