Hiroya Aihara
Representative, Ringo Tax Accountant Corporation

Thank you for visiting our website.
My name is Hiroya Aihara, Representative of Ringo Tax Accountant Corporation.
After graduating from university, I began my career in the tax accounting industry.
Throughout my work as a tax accountant, I have met many business owners who faced unexpected tax payments at the time of financial closing and struggled with cash flow as a result. I have also worked with many business owners who felt uncertain about how to manage the financial side of their business.
Through these experiences, I came to believe that business owners need a professional they can consult more easily about money, taxes, and financial concerns. This belief became the foundation for establishing Ringo Tax Accountant Corporation.
Tax and accounting are essential parts of running a business. However, they often involve complex terminology, and many business owners may feel unsure about what to ask or where to begin.
That is why we place great importance not only on providing accurate professional advice, but also on being a trusted partner whom business owners can approach with confidence.
For those who have recently started a business, as well as those looking to grow their company, managing numbers and cash flow is directly connected to business growth.
We aim to be more than a firm that simply handles tax filings. Our goal is to stand alongside business owners, think from the same perspective, and support them as a reliable partner throughout their journey.
We also provide services in English and support international tax matters, assisting foreign business owners and companies engaged in overseas transactions.
In today’s rapidly changing business environment, we believe it is important to support not only tax and accounting needs, but also the challenges and ambitions of business owners themselves.
We hope to remain a tax accounting firm that makes business owners feel, “I can reach out and consult with them.”
We will continue to improve our knowledge and services each day so that we can support our clients with sincerity, professionalism, and care.
We look forward to supporting you and your business.
