“Connecting the world to Japan”

Message from the Representative Director, Henry Tan

I originally moved to Japan in 2002, not thinking I’d be here so many years later. My positive experience with the country and its people changed that. I was fortunate in being able to help start this company with fantastic colleagues and top-tier clients. Since that time, we’ve helped hundreds of companies work in this complex market with success, and I’ve enjoyed the journey to get to where we are today.

Tricor Japan is not about profit. We believe profit is a result rather than a goal and that the sole purpose of our company is to help foreign businesses enter and work compliantly in Japan. We believe that our work benefits Japanese society greatly by helping clients bring in their unique products and services, hire local talent, and pay taxes. We help foreign business navigate an inherently complex regulatory market so that they can focus on their primary reason for entering the market – to introduce their products and services with success.

The most important thing I’ve learned over the many years working with clients is that focus is necessary for success in this market. We took that experience to heart. In 2011, we made a conscious decision to focus solely on foreign businesses in Japan. People questioned my decision to work only with foreign clients. I recall someone saying to me, “That’s like operating Disneyland but only catering to adults.” However, that particular focus has given us an inherent advantage over our competitors in developing a business culture that is sufficiently Japanese but with a Western mindset. Believe it or not, adults visit Disneyland as well.

Since our acquisition by Tricor Group in 2011, our business has grown rapidly. By offering similar services throughout Asia – the center of growth in the world – we have been able to graduate from “start-up” to one of the leading providers in the Japanese market. After the acquisition, I was asked to stay on for a period of two years, but I happily extended my tenure as CEO. For me, Tricor Japan is more than just a company, it’s a family, and I look forward to welcoming you to our home.
