Brands

• ロジ助 (Logisuke): Smart loading system for trucks - a smart cargo loading system mounted on trucks that automates cargo loading and unloading operations

Products and services

• ロジ助 (Logisuke) Smart Loading System Patent-pending truck-mounted smart cargo loading system that automates container loading and unloading using barcode scanning and touch-panel control. Features 23-container storage capacity (690kg max payload per container), automated loading/unloading with safety monitoring (container lid verification, displacement/tilt detection, chain-breakage detection, vibration protection), and DC24V battery operation (400 cycles per charge). Designed for logistics and delivery companies facing driver shortages in Japan, the system enables one-finger loading operation, eliminates the need to climb onto cargo beds, and supports diverse workforce participation including women and elderly workers. Specifications: 3620mm (L) x 1950mm (W) x 2000mm (H), 630kg total weight, 60-second in/out time per container, ±3mm positioning accuracy.
• Mechanical Design Services (設計サービス) Professional mechanical design services covering labor-saving devices, automation equipment, inspection jigs, processing jigs, welding jigs, conveyor systems, and construction machinery (bulldozers, power shovels). Leverages extensive experience to deliver rapid, multi-angle design solutions for industrial manufacturers. Major client: Komatsu Co., Ltd. (since 2001).
• Manufacturing and Fabrication Services (製造・製作サービス) Turnkey manufacturing and fabrication services for automatic assembly machines, automatic processing machines, automatic conveying systems, semiconductor assembly equipment, potting machines, and existing machinery modifications. Services span conceptual planning through design, fabrication, construction, and project management. Includes prototype and small-lot production support. Automation use cases reduce labor costs through improved production efficiency and stabilize quality through standardized processes that lower defect rates when combined with inspection equipment.
• CAD Education Services (CAD教育) CAD mechanical design education and instructor services, including on-site CAD training contracts conducted in Shanghai (since 2003) and Dalian, China (since 2006). Targeted at industrial clients requiring CAD-skills training for their engineering teams.

Scale indicators1 record

Recent moves7 records

Expansion highlights5 records

Regional players

• CKD Corporation: Japanese manufacturer of factory automation components and equipment, including systems for assembly and material handling. Comparable to Just in the FA equipment design space, but again at significantly larger scale as a public components supplier.
• Anritsu Corporation: Japan-based industrial automation and inspection equipment maker. Comparable to Just in its use of inspection and jig design within manufacturing processes, though Anritsu is a much larger instrument company rather than a design services firm.

Broad incumbents

• KNAPP AG: Austrian-headquartered logistics automation vendor offering storage, retrieval, and goods-to-person systems. Comparable to Just's Logisuke in the truck and warehouse loading automation space, but at enterprise scale serving global retail and logistics customers.
• Toyota Industries Corporation: Producer of forklifts, material handling equipment, and parent of Vanderlande, a global logistics automation integrator. Comparable to Just's Logisuke product and automation design services, but with orders-of-magnitude greater resources and international reach.
• Murata Machinery, Ltd. Diversified Japanese manufacturer of logistics systems, automated storage, and material handling equipment. Comparable to Just's automation and conveyor design work, but at industrial scale with global installed bases.
• Fanuc Corporation: Dominant supplier of CNC, robotics, and robomachine systems worldwide. Comparable to Just as a Japanese factory automation participant, though at vastly larger scale and focused on robotics/CNC rather than design services.
• Yaskawa Electric Corporation: Japan-headquartered industrial robotics and motion control leader. Comparable to Just in the FA/automation domain, but specialized in robotics and servo systems rather than mechanical design contracting.
• Daifuku Co., Ltd. Japan's largest material handling and logistics automation company, building conveyors, sortation, and automated loading systems at global scale. Comparable to Just as a domestic automation and material handling player, but operating at vastly larger scale and across far more verticals.
• Swisslog (KUKA / Swisslog Holding): Global intralogistics automation specialist (warehouse, distribution, and order fulfillment automation). Comparable to Just's Logisuke ambition in automating loading and unloading operations, but operating globally with extensive reference deployments.

Others

• SICK AG: Global supplier of industrial sensors and safety systems used in material handling and automation. Comparable to Just's Logisuke as an enabling technology provider for the same end-customer logistics automation use cases, though SICK is a sensor manufacturer rather than a system integrator.
