Tokyo-based Honda Motor Co. is reportedly entering into a strategic partnership with Toyota Motor Corp. to procure batteries for its hybrid vehicles from a U.S.-based Toyota plant, a move designed to insulate the Japanese automaker from potential tariff risks and bolster its supply chain resilience. The agreement, first reported by the Nikkei newspaper, signals a significant shift in Honda’s sourcing strategy amid ongoing trade uncertainties and increasing demand for hybrid vehicles in the American market.

According to the Nikkei report, beginning in fiscal year 2025, Honda will receive batteries manufactured at Toyota’s U.S. facility, sufficient to power approximately 400,000 vehicles – enough to meet the battery requirements for all of Honda’s hybrid car sales in the United States. While Honda has not officially confirmed the arrangement, a company representative acknowledged the information was not released by the company and stated that Honda does not disclose its mass production parts sourcing details. Toyota declined to comment on the matter.
Currently, Honda sources batteries for the vehicles it assembles in the U.S. from both Japan and China. However, the potential for increased tariffs under a renewed Trump administration has prompted the automaker to proactively diversify its supply chain and reduce its exposure to trade-related costs. This move follows a similar decision by Honda to produce its next-generation Civic hybrid in Indiana, rather than Mexico, to avoid potential tariffs on one of its best-selling models.
The Toyota plant in question represents a substantial investment by the automaker, totaling approximately $14 billion. Scheduled to open in April, the facility boasts four production lines dedicated to manufacturing batteries for hybrid vehicles. In late 2023, Toyota announced plans to expand the plant’s capabilities with an additional eight production lines for both Battery Electric Vehicle (BEV) and Plug-in Hybrid Electric Vehicle (PHEV) batteries, further solidifying its position as a key supplier in the burgeoning electric vehicle market.
The batteries sourced from Toyota are expected to primarily power Honda’s CR-V SUV, which is available in the U.S. as a full hybrid and, in California, as a hydrogen-powered electric drive. While the initial focus is on the CR-V, the Nikkei report suggests that these batteries could also be utilized in “other models,” although specific names were not disclosed.
The decision to secure battery supply within the U.S. is driven by a complex interplay of factors. The Trump administration’s imposition of additional tariffs on imports from China has already created uncertainty for automakers. Furthermore, a potential increase in import duties on automotive imports from Japan could significantly raise the cost of Hondas manufactured in the U.S., making them less competitive in the American market. Nikkei estimates that 25% reciprocal tariffs on Mexican and Canadian goods could cost Honda approximately $4.7 billion annually, highlighting the financial incentive to relocate production and diversify its supply chain.
The timing of this strategic shift is particularly noteworthy given the strong and growing demand for hybrid vehicles in the U.S. Honda sold over 300,000 hybrid vehicles in the U.S. last year, representing 22% of its overall sales in the country. This robust demand underscores the importance of a secure and reliable battery supply chain to meet consumer needs and maintain market share.
The partnership between Honda and Toyota represents a significant development in the automotive industry, demonstrating the proactive measures automakers are taking to navigate the evolving trade landscape and secure their position in the rapidly changing electric vehicle market. The agreement also highlights the potential for collaboration between competitors to address common challenges and capitalize on emerging opportunities. The coming months will be crucial in observing the full implementation of this agreement and its impact on both Honda’s and Toyota’s operations.
