The first time I visited the United States, I was 27. In fact, it was only several years ago when I recognized where Columbus, Ohio, actually was.
Kentaro Isa
Partner, CPA


As the partner in charge of the Japanese business services (JBS) practice in Ohio, I advise Japanese-owned manufacturing and distribution companies with U.S. locations. With my experience and knowledge of both the United States and the Japanese business and accounting environments, I help my clients eliminate the cultural gap between the two countries.

I was attracted to this career because I saw an opening for someone with my unique skills. I didn’t see many professional Japanese accountants in the United States who also had Japanese public accounting experience. Since there are so many Japanese manufacturing and distribution companies with operations in North America, I knew there was an opportunity to help both Japanese and U.S. management of those companies.

I’m proud that in my time at Plante Moran, I’ve been able to help expand our JBS practice and solidify our reputation in Ohio. I feel fortunate to work with so many talented professionals who also have a passion to help our clients, our staff, and our community.

I often speak to my clients and regional community organizations about the constant changes in the U.S. business environment, including new accounting standards in the United States and Japan, tax reforms, internal controls, and cybersecurity. I received my B.B.A. in economics from the University of Tokyo. I belong to the AICPA and the Japanese Institute of Certified Public Accountants.

Spending time with my family and friends is important to me. My wife always does a great job hosting Japanese-style parties. In Japan, I used to be a bookworm, commuting by train provided me plenty of time for reading. Now, I spend more time in my car, listening to the radio, music, and Rakugo (traditional Japanese storytelling).
