Toyota Boshoku America Acquires Full Ownership of TBDN Tennessee Company and Rebrands as Toyota Boshoku Jackson Tennessee, LLC
Toyota Boshoku America, Inc. (TBA) has announced a major strategic milestone with the full acquisition of TBDN Tennessee Company, LLC, the long-standing joint venture it has operated with DENSO International America, Inc. for more than three decades. The move marks a transformative chapter in the evolution of Toyota Boshoku’s North American manufacturing footprint and underscores the company’s ambition to strengthen its capabilities and sharpen its competitive edge in a rapidly shifting global automotive landscape.
For years, TBDN Tennessee Company has served as a cornerstone within the automotive powertrain components sector, producing a wide range of filtration and engine-related systems for leading automakers. The acquisition not only grants TBA complete operational control of the facility but also sets the stage for the rebranding of the entity as Toyota Boshoku Jackson Tennessee, LLC (TBJT). The new name reflects both the company’s heritage and its renewed commitment to the Jackson, Tennessee community where the facility has long operated.
A Strategic Move Rooted in Long-Term Growth
Since its founding, TBDN Tennessee Company has been recognized for manufacturing a comprehensive portfolio of critical automotive components — including air cleaners, air filters, cabin air filters, oil filters, oil mist separators, intake manifolds, and cylinder head covers. These components play essential roles in engine performance, fuel efficiency, emissions reduction, and overall vehicle reliability. The company’s production capabilities and engineering expertise have been essential to the success of Toyota Boshoku America’s supply chain network.
By assuming full ownership, Toyota Boshoku America is positioning itself to streamline business operations, strengthen alignment with its global strategies, and accelerate innovation across its filtration and powertrain product lines. The acquisition allows TBA to move with increased agility at a time when vehicle manufacturers are upgrading powertrains, enhancing efficiency targets, and integrating new technologies to meet evolving environmental regulations.
In announcing the acquisition, Shunichi Iwamori, President and CEO of Toyota Boshoku America, emphasized both appreciation for the decades-long partnership with DENSO and the importance of this turning point in the company’s history.
“We are grateful for the partnership and contributions of DENSO over the years,” Iwamori said. “This acquisition marks a pivotal step forward — allowing us to streamline decision-making, accelerate innovation, and enhance service to our customers and stakeholders. As we move ahead, we’re committed to elevating the Toyota Boshoku brand and expanding our impact across the industry.”
A Legacy of 35 Years and a New Beginning
Founded in 1990, TBDN Tennessee Company grew steadily into a respected manufacturer within the North American automotive filtration sector. Over its 35-year journey, the company has become known not only for its technical expertise but also for its strong culture of excellence, continuous improvement, and community engagement.
The timing of the acquisition aligns with the company’s 35th anniversary — an occasion that highlights its enduring legacy and the many milestones achieved through the collaborative efforts of Toyota Boshoku and DENSO. As the company transitions into Toyota Boshoku Jackson Tennessee, LLC, leaders emphasize that the rebranding signifies progress while preserving the core values that have shaped the organization since its inception.
“This name change represents an exciting new era,” said Shuhei Yoshida, President of TBDN. “While our name is changing, what matters most remains the same — our values, our dedicated team, and our unwavering commitment to our customers. We’re proud of our 35-year legacy and excited to build on that strong foundation. As a proud member of the Jackson community, we’re committed to cultivating meaningful partnerships that contribute to the region’s growth and long-term success.”
The company’s roots in Jackson have always been an integral part of its identity. For decades, TBDN has been a significant employer and contributor to the local economy, creating jobs, supporting community development initiatives, and building long-standing relationships with schools, nonprofits, and civic organizations. As TBJT begins this new chapter, Toyota Boshoku executives reaffirm the commitment to maintaining strong community ties and continuing to support regional growth.
Ensuring Continuity for Customers, Partners, and Employees
One of the most significant assurances in Toyota Boshoku America’s announcement is the commitment to operational continuity. Production of DENSO-branded products will continue seamlessly, maintaining supply stability and ensuring that OEM customers experience no disruption during or after the transition.
The company also emphasizes that the existing workforce — many of whom have decades of experience — will remain in place. Retaining the same team ensures that the knowledge, craftsmanship, and high quality that customers expect will continue uninterrupted.
This seamless transition is particularly important given the high level of precision and consistency required in the production of powertrain and filtration components. Automotive manufacturers depend on suppliers who can deliver reliability at scale. Toyota Boshoku’s approach to this acquisition reflects a deep understanding of those expectations and a commitment to meeting them.
Strengthening Toyota Boshoku’s North American Manufacturing Network
The integration of TBJT into TBA’s broader manufacturing ecosystem strengthens Toyota Boshoku’s presence in North America, where the company already operates multiple facilities specializing in interior systems, filtration products, and unit components. By owning TBJT outright, TBA enhances its ability to coordinate production, implement advanced manufacturing technologies, and support upcoming expansions across its product lines.
The move also reinforces the company’s global transition strategy as it adapts to broader industry changes such as vehicle electrification, hybrid powertrain optimization, and rising sustainability expectations. Filtration systems and engine component technologies continue to evolve in response to stricter efficiency and emissions regulations worldwide — a trend that will shape the company’s innovation roadmap in the years ahead.
With full ownership, Toyota Boshoku has greater flexibility to invest in research and development, introduce new product lines, enhance automation, and optimize manufacturing processes tailored to its long-term vision.
Celebrating a Milestone and Looking Ahead
To commemorate both the acquisition and the company’s 35 years of operation, Toyota Boshoku Jackson Tennessee will host an employee celebration in December. The event will honor the teams whose dedication and contributions have shaped the company’s success over three decades and will also serve as the first major gathering under the new brand identity.
The celebration symbolizes both gratitude for the past and optimism for the future. As TBJT embarks on this new journey under Toyota Boshoku America’s full leadership, the company is poised to strengthen its position as a trusted automotive parts manufacturer and deepen its commitment to innovation, operational excellence, and community partnership.
