Message from the President

Hiroaki Matsunaga

Yokohama Rubber (Thailand) Co., Ltd. Was established in 1996 in the Eastern Seaboard Industrial Estate, located 100 km southeast of Suvarnabhumi International Airport, a metropolitan airport in Thailand that has been in operation for 26 years.
Around the Industrial Estate, pineapple, mango and durian fields are scattered, indigenous products of Thailand, and it is a place of a beautiful natural environment.
Now, Yokohama Rubber (Thailand) Co., Ltd. manufactures high-pressure hoses for construction machines, hydraulic hose pipes and Teflon hose pipes for automobiles and sells to mainly Thailand and ASEAN countries and India. In particular, in Thailand, we maintain a large share of high-pressure hoses for construction machines.
As the surroundings of the Industrial Estate comprise an agricultural area, the Industrial Estate is required to have stricter standards for air and water quality than national standards and the Plant meets these standards. For maintaining safety, environment and quality, Yokohama Rubber (Thailand) Co., Ltd. holds ISO 45001, ISO 14001, ISO 9001,and IATF 16949 certifications and continues to acquire them.
