The Mazda Motor Corporation today signed an agreement with Iwakuni City and the Yamaguchi Prefecture to build the “Mazda Motor Corporation Iwakuni Plant,” a new facility for producing module packs using cylindrical lithium-ion battery cells supplied by Panasonic Energy Co., Ltd. Construction of the plant will begin in November, with operations scheduled to start in 2027. The Iwakuni Plant will be Mazda’s first new domestic facility since the Hofu No.2 Plant began operations in 1992.
Mazda is promoting electrification through its multi-solution approach, designed to flexibly address diverse customer needs. The Iwakuni Plant will be a key foundation for this global strategy, while also providing a safe, secure, and comfortable workplace and contributing to local employment and economic development.
The construction of the new facility marks an important milestone in Mazda’s transition, with its high-quality battery technology powering future electrified products and enabling the company to deliver attractive mobility solutions that meet increasingly stringent global emissions standards.
