Our Strong Points

Knowledgeable Professionals

We are not a large accounting firm, but we have knowledgeable staff members who are experienced in Big 4 accounting firms such as Ernst & Young. We have Japanese certified professionals to make sure our services are of the highest quality.

Affordable and Transparent Fees

We offer fair, transparent pricing policies that do not include any hidden costs. As previously stated, our services quality levels exceed that of the most expensive firms in Japan, and we believe that our fees are modest. We recognize that the most important thing is balance between “Quality” and “Price”.

I have used Shimada and Associates services for help with my taxes for the last couple of years. 
The service is very good. I always received a reply within minutes whenever I had questions and queries. They always provided me with clear explanations and every matter is handled smoothly. Dealing with Shimada & Associates is very reassuring as I know I can hand everything over to them and there are no problems. I highly recommend this company. 

Dr. Dirk Heinrich Neumann / JADEA K.K. CEO

With company headquarters in Berlin, San Diego and Tokyo, I can highly recommend the services by Shimada-san. He and his company work on solutions that were always suited to my company needs in Japan. Having a one-stop solution platform in Japan is very valuable and the friendly staff handles company matter bilingually. From a business standpoint, Japan has gotten more attractive over the past few years and requires companies to adapt fast in order to benefit from these changes. Transparent fee structures as well as knowledgeable staff make him a good and recommendable partner in Japan.

I highly recommend Shimada and Associates as a highly qualified accountant for both individuals and businesses. This past year, I was looking for a highly qualified english speaking accountant who would be able to handle my complex real estate related tax matters in Japan. Thankfully I was referred to Shimada and Associates as they not only had an office in Japan, but also was conveniently located in downtown Singapore where I currently reside.
Shimada was extremely professional and answered quickly and coherently every question I had regarding tax matters for myself and my entire real estate investor group. Shimada and his team expeditiously handled every inquiry presented, while recommending the most optimal solution regarding my tax filing. As a result we were all extremely pleased at how smooth the tax filing process ended up, and found Shimada to be extremely transparent. We are excited to continue using Shimada and Associates as our tax accountant given their depth and understanding of Japanese accounting rules and doing so at a very reasonable cost.
