Mr. Masaki Uchida

President

Isuzu Engine Manufacturing (Thailand) Co., Ltd. was established in 1987 and has been in business for 39 years.

We would like to express our sincere gratitude to all our customers, partner companies, members of the local community, and all employees for your continued support of our company.

Currently, the business environment surrounding Thailand and the ASEAN region is undergoing a major transformation. Changes in population structure, labor shortages, the shift toward electric vehicles (EV) and carbon neutrality, as well as intensifying global competition, are increasing the uncertainty facing the automotive industry more than ever before. On the other hand, we believe that the LCV and CV businesses, which support logistics, infrastructure, and commercial demand, play an essential role in sustaining society and offer new growth opportunities.

Until now, IEMT has prioritized safety and quality above all, leveraging its advanced technical capabilities and strong on-site expertise to pursue manufacturing that earns the trust of our customers. Going forward, through initiatives such as adapting to next-generation LCVs, advancing carbon neutrality, and strengthening human resource development, we aim to evolve Thailand from merely a production base into a value-creation hub that supports ASEAN and the global market.

Personally, I value the belief that “success is determined not by whether something can or cannot be done, but by whether we choose to do it or not.” We aim to be an organization that sees change not as a threat, but as an opportunity for growth, and that continues to take on challenges. To achieve this, we will focus on creating an environment where diverse talent can thrive and where local management can grow proactively and independently.

Moving forward, we will continue to strive for sustainable growth together with the local community and aim to be a company that consistently delivers new value to our customers.
