Komatsu has announced plans to establish a 270,000-square-foot parts distribution center in Mesa, Arizona, with development already underway and operations slated to begin by the end of 2026. Company officials say the new Western U.S. location is intended to strengthen parts availability and responsiveness across the region, improving service for dealers and the customers they support. The project is positioned as a strategic move to reduce transit times for parts deliveries and to increase equipment uptime for operators working in construction, mining, forestry and materials handling.
The Arizona facility will feature investments in automation, new storage systems and other operational enhancements aimed at streamlining the fulfillment and delivery of parts. Komatsu says the site will stock components for construction, mining, forklift and forestry equipment, maintain localized inventory to improve regional availability, and cut freight distance and overall transportation needs for many dealers. Those changes are expected to enable next-morning delivery for a significant number of Western dealers, shortening the supply chain between Komatsu’s warehouses and jobsite customers.
“This investment reflects Komatsu’s long-term commitment to strengthening support for our dealers and customers across the Western U.S.,” said Danny Murtagh, vice president of parts and infrastructure. “With expanded distribution capabilities and greater inventory availability positioned closer to our customers, we can respond faster, improve equipment uptime and deliver a better overall support experience.” The company framed the Mesa distribution center as part of broader infrastructure improvements intended to deliver tangible service benefits to dealers and equipment owners.

Komatsu operates dozens of supply and distribution sites across the United States and Canada that serve its construction, mining and forestry product lines, and the Mesa project adds to that network. Company representatives also confirmed plans to open a major new distribution center in Edmonton, Alberta, in the same year, expanding the company’s parts infrastructure in North America. The Mesa site is one of several recent investments the manufacturer is making to refine how parts move from warehouses to dealers, with an emphasis on automation and faster local delivery.

Komatsu says the localized inventory model will reduce freight distance and transportation requirements, a change the company expects will translate into more reliable and timely parts shipments. For dealers, shortened delivery windows and improved parts availability are intended to reduce machine downtime and support faster repairs in the field. The Mesa distribution center’s automation and storage upgrades are described as enablers for higher throughput and improved order accuracy, though Komatsu has not released detailed operational metrics or projected throughput figures for the new facility.
The announcement comes amid a series of product and technology introductions from Komatsu earlier in the year, which the company has been showcasing at industry events. Recent equipment debuts include the HM460-6 articulated dump truck, the D61PXi-25 dozer with IMC 3.0 intelligent machine control, the new D175AX-10 large production dozer, the PC158USLC-12 and PC158USLCi-12 tight tailswing excavators, and an expanded set of Smart Construction tools designed to turn jobsite data into actionable insights. Those product launches and the expanded distribution network reflect Komatsu’s broader push to pair machine updates with improved parts and service support.
Work on the Mesa site is ongoing, with Komatsu projecting operations to begin at the end of 2026. Company officials framed the investment as a long-term commitment to the Western U.S. market and to dealer support, emphasizing that closer inventory positioning and enhanced distribution capabilities are intended to speed response times and strengthen equipment availability for customers across the region. The Mesa center will join the company’s existing North American network of parts facilities, while Edmonton is expected to be another major addition to Komatsu’s distribution infrastructure within the same timeframe.
Komatsu is also constructing a separate 215,000-square-foot mining sales and service facility in Mesa representing an $80 million investment that will triple its current regional footprint and support up to 100 new long-term positions to boost Southwestern U.S. mining service capacity, according to the company’s North American investment overview.
