Our Strengths

Our strengths set us apart from other accounting firms. We have...

... an established track record of servicing Japanese companies

Notwithstanding our local origins, we have, through our quality service, won the trust and support of our Japanese clients. This can be seen from the fact that the vast majority of our clients are Japanese companies, with more than a quarter of whom consists of headquarters of international corporations and subsidiaries or branches of listed companies on Japan's stock exchange. We, therefore, have a wealth of experience to service the Japanese business community.

... a dedicated team of Japanese professionals
We have a team of Japanese professionals dedicated to servicing our Japanese clients. They are proficient in both Singapore and Japanese regulatory and technical requirements on accounting and taxation, and bilingual in English and their native Japanese language. Hence, we are able to communicate effectively with our clients, better understand their needs and provide quality services to them.

... affiliates to provide seamless integrated service solutions
From our core assurance services, right down to tax, compliance and business advisory, our firm and its affiliates are well-positioned to address your business needs.
