Technoa Co., Ltd. (Headquarters: Gifu City, Gifu Prefecture, Representative Director: Koji Yamazaki) will hold a limited-time summer special event, "Monozukuri DX CAMP," from Saturday, August 9, 2025, to Saturday, August 23, 2025. Small and medium-sized manufacturing companies face challenges such as a shortage of specialized personnel and a lack of know-how and information, which act as barriers to promoting DX (digital transformation). This event will provide a step-by-step approach to "realistic DX," based on the know-how accumulated by Technoa while supporting the DX transformation of small and medium-sized manufacturing companies. It will be structured as DAY.1 to DAY.5, offering an opportunity for skill development during the summer break and supporting the learning and growth of small and medium-sized manufacturers.
