We will be exhibiting at the "Mechanical Components Technology Exhibition (M-Tech)" held at Tokyo Big Sight from July 1 (Wednesday) to July 3 (Friday), 2026. This year, under the theme "NEXT STAGE - The Challenge of 100-Year Companies," we will showcase various components that are active in multiple fields, including conveying robots, semiconductor manufacturing equipment, retail, kitchen-related, construction machinery, and the delivery industry. The highlight of our exhibition is the "Motor Lock." The "Motor Lock" possesses overwhelming power not found in electric locks, while being an energy-saving product with low electricity consumption. Through energy conservation, it not only contributes to CO2 reduction from an eco-friendly perspective but also optimizes the power-on time, which can help suppress heat generation. Additionally, our comprehensive catalog has been renewed for the first time in six years and is now available for shipping. It covers all catalog products, including new items, and consists of a substantial 1,390 pages. We invite you to visit our booth (East Exhibition Hall, Hall 3, 28-32) to experience the actual operation and feel of our products. *For more details, please feel free to contact us.
