Message from Managing Director

Nowadays, many countries around the world have a major concern of environmental issues caused by over-emission of carbonyloxies which came from vehicles or electric produced from Lignite. As a result, these situations will lead to serious problems and long-term damages on people’s health and well-being.

Therefore, many countries in Asia may seriously choose green energy such as electricity instead of fuel in their mass transit systems.

Currently, Kantou Maintenance Asia Co., Ltd. (KMA) is a specialist in electric mass transit installation and maintenance services since we have been completed successfully extensively in Japan.  Moreover, we have good relationships with Japanese manufactures and electric railway companies for a long period.

KMA’s goal is to provide high technologies of mass transit system to Thailand as well as the other countries to be able to improve the countries together simultaneously. Therefore, in our first step, we aim to start in Thailand by pioneering electric mass transit system with our specialized technical training center. Then, spread out the technology to Asia.

KMA does not only aim to raise the standard of electric train system in Thailand, but also aim to improve the potential of human to meet international standard.
