Company Profile


Comprehensive partner

Nobuo Irisawa

Yasuo Usui Accounting Firm, the forerunner of Yotsuya Tax Corporation, was established on January 1, 1984 and over the past two decades, we have contributed to help increase the value of our clients’ businesses. Our greatest strength is our ability to offer a wide range of services through cooperation with affiliated companies and professionals in other fields such as attorney at law.

Yotsuya Tax Corporation provides much more than the traditional services of licensed tax practitioners and certified public accountants. We have a great deal of experience in providing tax-consulting services to not only domestic corporations, but also nonresidents, foreign corporations and Japanese subsidiaries of foreign corporations. Our aim is to provide all our clients with the advice best suited to their individual circumstances.
