Corporate Philosophy: Committed to Quality

KTC tools are widely used in Japan’s automotive industry and by motorsports teams. Our reputation for high quality has made KTC the leader in Japan’s tool market for many years. At KTC quality encompasses not only high precision and safety; our tools are specially designed and manufactured to ensure ease of use and high user satisfaction. KTC’s quality control and environmental management systems meet stringent international standards, while contributing to a recycling-oriented society and enhancing customer satisfaction.

Design & Development Philosophy

For both professional automotive technicians and skilled amateur mechanics, tools are much more than mere devices for tightening and loosening nuts and bolts. Well-designed tools communicate a variety of subtle information to the user. For this reason KTC tools are designed not only to feature the ideal balance between lightness and strength, but also to be very user friendly. Because KTC tools facilitate tactile communication between the work and the worker, jobs go more smoothly and the technician works with greater comfort. This tool/technician relationship is at the essence of what makes KTC tools so special.

KTC tools are not only a pleasure to use; they are specially designed with safety in mind. For example, although increasing the hardness of a tool increases its strength, excessive hardness can cause brittleness. If a tool breaks its user could be injured. KTC tools are designed to have the ideal balance between strength and flex. If a tool is overstressed to the point where it may fail, it communicates this to the user. To protect the user in the unlikely event that a tool should fail, KTC carries out extensive failure testing and stress analyses to strategically predetermine the weakest point and thereby ensure maximum safety.

Integrated Production System

Many Japanese tool manufacturers design their products in Japan, but rely on foreign manufacturing plants to produce them. At KTC, for more than 60 years all of our products, with a few exceptions, sold directly to professional automotive technicians and amateur mechanics have been designed and manufactured in Japan using our integrated production system. This system offers three important advantages.

Because our development, production and sales teams work together, they produce innovative tools that are industry leaders. All staff attend all development meetings and work closely with the developers at all stages of the process. If the production side notices a potential problem during development, that issue is efficiently resolved prior to production.

While other companies entrust a part of their production work, like forging or surface treatments such as chrome plating, to outside vendors, at KTC all production steps are conducted in-house. This enables comprehensive problem solving of any issue that arises during production and ensures both high production efficiency and excellent control. It is here that KTC’s many years of know-how and unique technologies come together.

Because this system allows direct checking of every process from forging and machining to heat treating and plating, the result is a very efficient and high level of quality control. This is followed by final inspections, including inspections to ensure the tools can withstand the loads imposed on them by automotive technicians with a high margin of safety.


Because Japan’s global automotive industry requires compliance with environmental impact and quality management, KTC’s business meets international standards.
