Concrete technological capabilities demanded by the world.

New High-Quality, High-Efficiency "Total Assembly" Production System.

TOA's "total assembly" production system helps us more efficiently produce our wide range of products while maintaining the highest quality. In this system, several workers form a work station, and each station completes the entire assembly of their assigned product, taking responsibility for all production processes, from parts purchasing to the supply of the finished product. This has resulted in a significant increase in product precision, greatly minimized waste and heightened production efficiency, while increasing the speed with which our products can be shipped to market.

TOA has received certification under ISO9001 international standards for quality assurance, in recognition of TOA's establishment of a total quality control system for manufacturing activities ranging from product planning to development, production, installation and after-sales service.

As a result of these efforts, TOA has also received ISO14001 certification, the international standards for environmental management systems. Further, TOA has achieved Level 2 of the CMMI (Capability Maturity Model Integration) international index for businesses involved with railway vehicles, which evaluates software development processes to ascertain the degree of capability attained.
