Greetings
Aiming to be accountants and tax accountants who are "easy to consult with"
Thank you very much for visiting our office's website.
I have worked in the finance and accounting departments of many companies at a major auditing firm, where I have come to realize the significant impact that financial strategies have on a company's growth. In particular, I have witnessed how small and medium-sized enterprises struggling with cash flow and management decisions can grow dramatically by establishing an appropriate financial foundation, and this has strengthened my desire to work closely with business managers to provide support. In 2020, I left the auditing firm to engage in consulting and IPO support for small and medium-sized enterprises. I have been involved in consulting and IPO support for many small and medium-sized enterprises, supporting the development of their businesses while working closely with their managers.
While large companies have a wealth of resources and experts, I feel that there are still few opportunities for small and medium-sized enterprises to receive the same level of support. Therefore, I decided to open this office with the hope of utilizing my experience to help small and medium-sized enterprises build a stronger financial foundation and achieve sustainable growth.
Tax and finance are not just about managing numbers, but are important elements in creating the future of your business. We want to be a trusted partner to those who run businesses in various forms, including those involved in corporate management, side jobs, freelancing, and micro-corporations.
I am a father of one child and I am also struggling with child-rearing every day. I would be happy to build a relationship with my clients where we can talk casually about not only tax and financial matters, but also about child-rearing and small everyday events.
I am committed to supporting your business and financial growth as both an expert and a person.
