Process until cars are completed

The car manufacturing process can be divided into 3 main stages.(Click the button for each stage to display a detailed explanation.)
1 Development 矢印 2 Production Preparation 矢印 3 Production


Developing refined products through innovation, progress and teamwork focused on the future. development
While developing technologies for future generations,the development group is working hard to create new models,keeping a close watch on ever-changing enviroments and lifestyles.To create ideal vehicles,we have been pursuing improvement in concept,style and design. Our insariable thirst for vehicle development serves as a source of the birth of next-generation vehicles. The creation of ideal vehicles cannot be accomplished without the excellent teamwork of the development group that has attained the following achievements:skills in planning and design,capable of satisfying our customers;and the series of processes from body design to prototyping and evaluation,which serves as support for the competitiveness of our products.To create new means of mobility for future generations,we are engaged in research and development for our ideal vehicles in an uncompromising manner.

Production Preparation

Support technology which creates products within manufacturing processes. Seek quality and efficiency. Production Technology
To create quality vehicles,high-level production preparation is required. A worker-friendly production line of high quality and low cost for high-mix low-volume manufacturing can be achieved by applying the following to the production line:press dies to realize aesthetic designs created by the design division,and assembly jigs and welding/painting robots to precisely realize body frames.Technological skills are needed to develop production lines that are constantly evolving along with the evolution of vehicles.Comprehensively considering all the processes for the production of well finished vehicles,we are devoted to equipment planning and production-line organization to develop efficient production lines.

Our technological capability or [craftsmanship] is highly recognized by expert international institutions Production
At our four production bases,the Miyagi Ohira,Miyagi Taiwa,Iwate,and Higashi Fuji Plants,vehicles are being manufactured safely with effective,worker-friendly production lines organized in such a way that the burden of workers can be reduced by applying robots and automatic conveyors at each production process.
To establish advanced skills backed by individual worker's wisdom and experience as manufacturing technology,not only the production sites but also the development and production preparation groups work as an integral whole,implementing kaizen by utilizing workers'wisdom and ingenuity to find the best way to produce quality vehicles skillfully and quickly at reasonable cost.
