subsidiary of Nippon Steel Corporation (Nippon Steel) and a manufacturer of cold-rolled steel, hot-dip
galvanized and galvannealed steel sheets, and tinplate steel in Thailand, received third place at the 6th
Edition of the Global KAIZEN Award. This award is presented by the Kaizen Institute, Ltd. (established in
1985, and headquartered in Switzerland) and honors organizations for their outstanding achievements in
implementing KAIZEN principles and practices. NS-SUS entered the award program with its company-wide
improvement activities (the “NS-SUS Way”) and results in the areas of manufacturing, sales,
and indirect departments. The company ranked first in the Thai national round held on September 6, 2024
and was consequently selected to represent Thailand. In the global round held on November 12 of the same
year, the company ranked third out of 15 countries (with about 500 participating companies in
total).
In the global round, NS-SUS’s improvement activities (the “NS-SUS Way”) were judged to
be 1) company-wide and sustainable as well as fully established within the organization; 2) making steady
achievements in various areas such as safety, the environment, equipment maintenance, and quality while
utilizing DX technology; and 3) contributing to improving corporate profits through measures such as
increasing customer and employee satisfaction as well as reducing costs. These results were judged to
align with the five KAIZEN principles*1 advocated by the KAIZEN Institute.
Behind these achievements are the improvement activities employing the TPM*2 method that NS-SUS has been
working on as company-wide activities since 2005, focusing on equipment maintenance, productivity
improvement, and skills transfer. NS-SUS will continue to work tirelessly on improvement activities with
the cooperation of all managers and employees, and will continue to strive to fulfill its mission of
“Contribute to society and pursue happiness of all stakeholders”.
