Inheriting the core philosophy of the heavy-lift transport drone 'Karusuke 55,' this new entry-level model supports field adoption from both cost and practical operation perspectives. Karusuke 25 Mazex Co., Ltd. (Headquarters: Higashi-Osaka City, Osaka Prefecture; CEO: Hiroaki Yoshino; hereinafter “Mazex”) announces the release of its new 25kg-payload transport drone, 'Karusuke 25 (Karusuke Nijuu-go).' Designed as an entry-level model to meet growing demand for drone-based transportation in forestry, construction, and civil engineering sectors, Karusuke 25 focuses on essential field requirements, achieving an accessible price of 1.9 million yen (excluding tax) while maintaining high practicality. In recent years, forestry, construction, and civil engineering sites have faced increasingly severe challenges, including chronic labor shortages, an aging workforce, stricter safety regulations, and rising workloads. In particular, transporting materials, tools, seedlings, surveying equipment, and safety supplies to remote mountainous areas, sloped terrain, or locations inaccessible to vehicles consumes significant time and labor, greatly impacting overall site productivity. Moreover, these sites often face structural inefficiencies where skilled workers’ time—meant for core tasks such as construction, logging, surveying, and installation—is diverted to routine transport duties. Manual carrying in difficult terrain or steep slopes not only imposes heavy physical strain but also increases risks of falls, slips, and collision accidents. As site teams shrink, optimizing task allocation by clearly distinguishing between work that should be performed by humans and work suitable for technology is becoming increasingly critical. Against this backdrop, transport drones are gaining attention as an effective solution for reducing labor, improving efficiency, and enhancing safety. At the same time, field operators frequently express the need for more accessible entry points: 'We’d li
