What Komatsu Japan does

Komatsu Customer Support Japan Ltd. (コマツカスタマーサポート株式会社, KCSJ) is the wholly-owned Japanese domestic sales, service, and rental subsidiary of Komatsu Ltd., established in April 2018. The company markets and supports Komatsu-branded construction equipment, forklifts, special-purpose vehicles, attachments, parts, and ICT solutions across Japan, operating approximately 200 service locations from Hokkaido to Okinawa and 11+ IoT Centers dedicated to Smart Construction demonstrations and training.

Its core product portfolio spans hydraulic excavators (PC78US-11, PC138US-11, PC200i-11, PC300i-11), mini excavators, bulldozers (D37PXi through D155AXi-8 ICT variants), wheel loaders, dump trucks, and a full forklift range including FE25/30 electric and FE25G/30G lithium-ion models. The flagship platform is Smart Construction, an end-to-end ICT construction solution covering 3D surveying (Smart Construction Drone/Edge/Quick3D), execution (3D Machine Guidance Retrofit and Flex, Quick Smart Construction), and site management (Dashboard, Fleet/Tracking Management System, Simulation, Design3D, Teleoperation). Komtrax telematics provides continuous fleet monitoring, and 12+ NETIS-registered technologies plus GX Construction Equipment Certification for seven electric models reinforce government procurement positioning under Japan's i-Construction mandate.

Revenue is generated through a mix of one-time equipment sales (new and used construction machinery, forklifts, attachments, parts) and recurring streams including rental services, R&M Partner long-term maintenance contracts, Komatsu Care Plus / Komatsu Care Long service plans, Total Merit Plan for forklifts, Oil Clinic diagnostics, and Smart Construction ICT subscriptions. Distribution is conducted exclusively through authorized domestic dealers with enterprise field sales, IoT Center demonstrations, trade shows (CSPI-EXPO, CEATEC JAPAN), digital channels (YouTube, Facebook, Smart Construction Weekly newsletter), and partner-led deployment via 100+ surveying/measurement companies and the EARTHBRAIN joint venture. Customer segments include civil engineering contractors, demolition operators, mining/quarrying firms, forestry and sawmill operations, logistics/ports, agriculture/livestock, recycling, snow removal, and government/public works.
