                KM Kikaku is a domestic manufacturer with over 40 years of history in the airsoft custom parts industry.

                We develop, manufacture, and sell a wide range of airsoft gun parts and accessories, including the popular "TN Barrel" and "Silencer," which are highly acclaimed not only in Japan but around the world. As a symbol of trust and quality, all our products are manufactured in Japan.

                Utilizing expertise based on many years of research and experience, our custom parts combine functionality and durability to meet the needs of airsoft enthusiasts, earning them strong support and trust.

                In order to strengthen our own brand, KM Kikaku has consistently developed its own in-house production line that makes full use of CNC machine tools, and produces precision custom parts under strict quality standards.

                Our own factory is equipped with an advanced manufacturing line and precision measurement booth, and we handle all processes in-house, from design to prototype manufacturing and effectiveness verification, making it possible to develop products with the true performance required by the market.
