About us

Greetings from the Representative Director

“To provide the highest quality services in English to global customers.” 

Since our establishment in September 1989, we have consistently offered services such as taxation and accounting in English. This initiative stemmed from the stark realization, during my transition from working in auditing firms and foreign financial institutions to entrepreneurship, that the number of accountants providing tax and accounting services in English was alarmingly low compared to lawyers offering legal services in English. It was this firm belief in a substantial latent demand for these services in English that prompted me to embark on this journey. 

Over the past 30+years, we have proudly positioned ourselves as pioneers in this industry, continually providing services that delight our clients. Currently, over 90% of our clients are multinational corporations, with headquarters spanning more than 20 countries worldwide. 

The high quality of service we strive for involves delivering practical solutions, supported by knowledge and experience, to clients worldwide in a timely manner and in English, while working hard to understand their perspectives. 

In addition to services tailored for multinational corporations, we also offer tax and accounting consulting for Japanese companies expanding overseas, and tax advice for Japanese individuals regarding international inheritance. These services have become possible through the network we have cultivated over the years with reliable accountants worldwide. 

With direct investments from multinational corporations into our country, the global expansion of Japanese companies, and international inheritance for Japanese individuals across borders accelerating amid the globalization of the Japanese economy and society, we are committed to deepening our dedication to excellence, ensuring our services are appreciated by our clients and genuinely beneficial. We look forward to further honing our skills and knowledge in the service of our clients in the future.
