Mazex Releases Transport Drone 'Karusuke 25' with 25kg Payload Capacity

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 like to start with an affordable model,' 'We want a practical, easy-to-operate drone with sufficient performance,' and 'We need a realistic drone suited for daily transport, not just high-end models.'

Karusuke 25 was developed precisely to meet these needs. Leveraging technical expertise gained from developing and operating forestry transport drones 'Mori-to' and agricultural drones 'Tobi-suke' series, Mazex streamlined onboard features to essential functions, achieving both an accessible price of 1.9 million yen (excluding tax) and practical usability for sustained field operations. Karusuke 25 aims to become a viable new option, enabling broader, more realistic adoption of transport drones beyond just a few advanced sites.

Background of Karusuke 25 Development

While the effectiveness of transport drones is now widely recognized, the initial adoption phase often faces two major hurdles: 'cost' and 'sustained implementation.' High-performance models may be difficult to justify financially, and even when acquired, they won’t be fully utilized without systems enabling continuous, practical operation.

Through years of developing and supplying drones for forestry and transport, Mazex has gained deep insights into real-world operational challenges. With Karusuke 25, the company prioritized both 'affordable adoption' and 'practical field usability,' focusing on design principles that support daily, sustained use rather than merely maximizing specifications.

Key Features of Karusuke 25

Affordable price of 1.9 million yen (excluding tax) significantly lowers the barrier to adopting transport drones Many organizations understand the benefits of drone transport but hesitate due to high initial investment. With its strategic pricing at 1.9 million yen (excluding tax), Karusuke 25 offers a realistic option for companies and sites previously deterred by cost. It is ideal for initial deployment—enabling users to start with one unit and gradually expand drone transport capabilities.

25kg payload capacity meets practical, everyday transport needs Designed to handle routine transport tasks in forestry, construction, and civil engineering—such as seedlings, tools, materials, components, and supplies—Karusuke 25 avoids excessive over-specification. Its payload capacity is carefully calibrated for real-world usability, making it easy to envision practical implementation after adoption.

Despite maintaining a 25kg payload, Karusuke 25 achieves a 64% reduction in footprint area compared to the existing 'Mori-to 25,' making it more compact than most 25kg-class transport drones in Japan. This compact design enables operation in tighter spaces, forests, and construction sites, expanding deployment possibilities.

Streamlined functionality for easy adoption Karusuke 25 emphasizes core performance required in transport operations, minimizing onboard features to essential functions. This simplification makes the drone easier to handle, especially for first-time users, reducing both psychological and practical barriers to deployment—not only in terms of cost but also in operational readiness.

A model in the Karusuke series, inheriting core design principles from Karusuke 55 Karusuke 25 is based on the fundamental specifications and design philosophy of Mazex’s heavy-lift drone 'Karusuke 55,' adapted for a 25kg payload. Karusuke 55 was developed to improve efficiency and reduce labor in challenging environments such as sloped and mountainous terrain, incorporating field-proven features like anti-resonance mechanisms, automatic release hooks, dual-operation functionality, RTK compatibility, and waterproofing.

Focus on sustained usability, not just affordability For transport drones, long-term success depends not only on purchase price but also on the ability to operate continuously without interruption. Mazex emphasizes not just drone sales but also sustainable battery management practices. The system visualizes battery levels and health, detects anomalies, and supports safe, long-term use. Recognizing that transport operations often require near-continuous flight cycles, Mazex recommends rotating two pairs (four units) of batteries—charging one pair while flying with the other. This minimizes downtime, allowing simultaneous cargo loading/unloading and preparation for the next flight, thereby maintaining smooth workflow rhythms. Additionally, the ability to start operations with just one generator and two chargers further enhances field practicality.

Battery Management System

With Karusuke 25, Mazex continues to prioritize not just flight capability but sustained, practical usability in real-world operations, advancing the pursuit of user-friendly transport drones.

Target Use Cases

Forestry Sector: Transport of reforestation materials, seedlings, wildlife deterrent supplies, and tools. Particularly effective in reducing transport burdens to steep slopes or locations far from access roads.

Construction Sector: Transport of tools, components, and construction materials in mountainous or uneven terrain. Helps reduce worker round trips, enabling greater focus on core construction tasks.

Civil Engineering Sector: Transport of surveying equipment, repair materials, and safety supplies in areas where manual carrying is labor-intensive. Provides a flexible transport solution in vehicle-inaccessible locations, improving overall site efficiency.

Karusuke 25 contributes to labor reduction, improved efficiency, and enhanced safety in sites where vehicle access is difficult or where workers face heavy burdens from repeated manual transport. By focusing not only on drone performance but also on practical operation—including battery management—Mazex aims to deliver practical solutions suited for today’s increasingly understaffed worksites.
