TSS's Attention to Detail

One of the characteristics of the Japanese is that we pay particular “attention to detail” in our craftsmanship. This particular attention to detail is engrained into us from a young age and upbringing, which Japanese people can sometimes take for granted, but is a process that is not found amoung the rest of the world. In other countries, people might speculate that it is not necessary to be so particular on everything. Surprisingly, it is something that the Japanese do normally, and we at TSS pride and utilize this attention to detail that cannot be replicated through any procedures, manuals, or education.

However, in this world, there are always two sides of the coin. This meticulousness may help create better work, such as improving quality and performance, and increasing the added value of products, which will often provide new experiences that will help bring new success in the future. However, due to this diligent effort to find perfection, it is possible to simply continue to produce results that will not only just be expensive, but you will not be able to incorporate new techniques and thoughts as well.

The Japanese manufacturing industry has been dragged by the bad side of this paid “attention to detail”, and many companies, including TSS, must feel that they have driven themselves into a corner. Japan, which has been leading the world in manufacturing, is now in need of studying manufacturing in the world and follow in the footsteps of other innovators, especially in low-cost producing countries. Needless to say, the “craftsmanship” that is the identity of Japanese manufacturing should not be easily thrown out the window either. Rather, we believe that we have an obligation and responsibility to continue to provide products with a strong commitment to Japanese manufacturing throughout the world. We devote ourselves to ingenuity to provide our customers with products that have the perfect balance of quality, cost, and delivery time while executing our “attention to detail” in our products.

Together with the people of the world, we at TSS will continue to make and deliver products with Japanese manufacturing and its “attention to detail.” I believe that is the path for Japan and the Japanese manufacturing industry to keep on thriving.
