Since its founding in 1931, Yamashita has valued its customers and grown alongside their development, embodying the pioneering spirit of its founder. It is not too much to say that we owe our development to our customers’ support.
Our business has primarily focused on the engineering and manufacturing services for power plant equipment. In the future, however, we aim to leverage this experience to expand our business into equipment for various fields.
In terms of the engineering service, we introduced 3D CAD software and analysis software ahead of other companies in the industry. For the manufacturing service, we have made early investments in advanced machinery to facilitate the seamless collaboration between 3D CAD and the manufacturing process. Furthermore, we are also actively embracing Digital Transformation.
Equipped with these state-of-the-art machinery, software, and highly experienced and trained professionals, we remain committed to meeting our customers’ needs and providing customer-first services while achieving employee satisfaction.
