Why Yamanouchi? |
We have attained a remarkable position in the market by offering supreme quality products and services to our clients. Listed below are just a few of the factors behind our success: |
 |
Quality products and services: the YSEC Group are more than capable of operation, fixture designing and planning, and sample production as heavy industrial companies in Japan, whilst other Japanese sub-contractors (Tier 3) normally undertake piecework of pre-products by heavy industry.
Timely and quick execution capability: quick decision making is one of the big advantages of SME. The CEO Mr. Yamanouchi can make a decision by himself on every matter. In the case of his absence, the executives listed below can also handle such matters.
-Mr. K. Shiraki (CEO of YSEC, for manufacturing cases)
-Mr. K. Abe (CEO of JASPA, for purchase/cost cases)
Efficiently coping with changes: with the original operation system that has an exclusive property not seen even in heavy industrial companies, the YSEC Group are capable of adapting to mechanical change without causing delays or wasting time, whilst other manufacturers usually take a few days to change the procedure and operation system.
A team of qualified and experienced professionals: assembling a special team for a project enables all personnel to be made aware of any sudden change in schedule cases and to demonstrate their own efforts to the high-priority tasks.
-See the YSEC Organisation Chart
24-hour-operated and automated manufacturing system: the unattended system unit is equipped with an IC chip to common-attachable pallet for all the machines which has reduced human error and led to 30 percent-less defects so far. In addition, information of the tools are all compiled in a data-base and are completely traceable. Longer operation than manned-systems has led to an increase in productivity on a daily basis, and also raised the cost effectiveness.
Practical error detecting environment: When an error occurs the machines automatically stop and shift to the following process. Our integrated production control system ensures an accurate and quick response to the problem should one occur, prescribing appropriate and specific measures for remanufacturing and repair.
Traceability: this system of traceability not only avoids repeating the same mistakes of creating defects, but also enables the control of every area in the manufacturing process such as accepting orders, material conservation, process control, shipment documentation, and our own purchasing management and records, and introducing this system to sub-contractors enables us to have a consistent control operation. |

Yamanouchi’s Distinctive Advantage
- Strong Coalition with Local Government
Affective collaboration on projects with the Niigata City local government (Niigata Prefecture). The local government have efficient and experienced SMEs in the prefecture that are more than adequate for the high-tech needs under the support and understanding of the mayor of Niigata City which is why the YSEC Group obtain strong backup for policy and financial aspects. |
