Mazda Completes Hiroshima Parts Hub Ahead of 2027 Start
Mazda has completed a new logistics center at Hiroshima Port that will supply knockdown parts to every Mazda vehicle-production site outside Japan. The Mazda KD Center, built in the Dejima district, is scheduled to begin operating in January 2027 after construction that started in April 2025.
The project is an industrial and supply-chain story rather than a new-model announcement. Mazda did not disclose annual shipping capacity, a list of individual destination plants or a vehicle-production forecast. What the company did confirm is that the center will receive, store and pack parts, then load them into ocean-freight containers for assembly operations abroad.
What a knockdown-parts center does
“KD” refers to knockdown parts: vehicle components shipped from a central source to another factory for local assembly. Automakers use this model to support overseas production while sharing engineering, tooling and supplier output across markets. The logistics center does not assemble finished vehicles; its role is to prepare and dispatch the parts that overseas plants need.
According to Mazda’s November 6 announcement, the Dejima facility replaces an older KD center in the Kaita district of Hiroshima Port. The national government and Hiroshima Prefecture have expanded Dejima’s international container terminal and its ability to handle larger vessels. Mazda says locating the replacement center beside that infrastructure should make parts supply more efficient and reliable.
The site covers approximately 55,000 square meters, or 13.6 acres, while the building itself occupies roughly 35,000 square meters, about 376,700 square feet. Mazda held a completion ceremony in November and plans to start operations in January.
Automation is aimed at handling and worker safety
Mazda says the new center automates storage and retrieval of parts as well as the process of packing components onto pallets. The announcement does not identify the equipment vendors, automation rate or staffing change, so it would be inaccurate to infer a fully autonomous warehouse or a specific labor reduction.
The company also designed separate routes for pedestrians and vehicles. That physical separation can reduce interaction between workers, forklifts and delivery trucks, though Mazda did not publish an independent safety assessment or a target for incident reduction.
Zoned air conditioning is installed throughout the building, an unusual detail for a logistics announcement but a useful indicator of the company’s emphasis on working conditions. The center also includes a driver lounge for truck operators waiting while parts are unloaded.
Truck entry procedures have been streamlined, and Mazda says dedicated forklift operators will unload supplier vehicles. The stated goal is to shorten handling time and reduce the burden on drivers. No average turnaround time or before-and-after comparison was released, so the size of that improvement remains unverified.
A 2.2-MW rooftop solar array
The roof carries solar panels with 2.2 megawatts of generating capacity. Mazda says the system will supply part of the electricity used at the facility, but it has not disclosed expected annual generation, the center’s total power demand or the percentage of consumption the array will cover.
The installation fits a broader pattern in Mazda’s domestic operations. Chiefs Review previously reported on Mazda’s solar and battery-storage plans at two other Japanese sites, where the automaker is also working to reduce grid demand and operational emissions.
Generating capacity should not be confused with energy production. A 2.2-MW rating is the array’s maximum output under suitable conditions; actual electricity generated over a year will depend on weather, orientation, maintenance and curtailment. Mazda’s announcement does not provide those figures.
Why the center matters to Mazda’s overseas plants
A single disruption at a parts-consolidation hub can affect multiple factories, so the new center’s importance extends beyond Hiroshima. Its receiving, storage, packing and container-loading functions sit between Japanese suppliers and Mazda’s overseas assembly sites. Faster handling and access to a strengthened container terminal could reduce delays, but Mazda did not promise a specific lead-time reduction.
The facility is also exposed to the same risks that affect global automotive logistics: port congestion, extreme weather, labor interruptions, shipping capacity and component shortages. A modern warehouse can improve control inside the site without eliminating those external constraints.
Mazda Chief Supply Chain Officer Kazuhiko Sumi described the center as a starting point connecting Hiroshima’s manufacturing capabilities with production sites abroad. That is the company’s strategic framing. The independently established facts are more concrete: the building is complete, operations are planned for January 2027, its core handling processes include automation, and its rooftop solar system is rated at 2.2 MW.
The next meaningful milestones will be the operational start and evidence of performance after shipments begin. Until Mazda publishes throughput, delivery-reliability or energy-use data, the center should be viewed as a new piece of supply-chain infrastructure rather than proof of a quantified production improvement.
