In the late 1940s, Toyota faced severe shortages of cash, materials, and equipment after World War II. Leaders including Taiichi Ohno and Eiji Toyoda began shaping an alternative to U.S.-style mass production that could work with small batches and many product variants. This period is widely treated as the starting point for what became the Toyota Production System (TPS).
In the early 1950s, Eiji Toyoda visited Ford’s River Rouge complex and studied large-scale integrated manufacturing. Toyota concluded it could not simply copy Ford’s approach because Japan’s market size and Toyota’s resources were different. This comparison helped Toyota focus on flow, problem-solving, and tight control of inventory rather than high-volume scale alone.
Toyota’s 1950 labor dispute, triggered by financial crisis and restructuring pressures, ended with layoffs and management changes. The crisis reinforced Toyota’s need to raise productivity and stabilize operations with fewer resources. These constraints became a practical driver for systematic waste reduction in manufacturing and logistics.
Toyota began turning supermarket-style replenishment into a clearer signaling method using kanban (information “signboards” or cards). Toyota sources describe applying this logic in a main plant machine shop in 1953, helping coordinate production to actual downstream use. Kanban would later become a core tool for limiting work-in-process and preventing overproduction.
In 1954, Toyota introduced the “supermarket method” as a new way to control how parts moved from earlier processes to later ones. The key idea was that the next process should take only what it needs, when it needs it—like customers taking items from store shelves. This approach became a major step toward Just-in-Time (JIT) production inside Toyota plants.
In 1954, Taiichi Ohno became a director at Toyota, increasing his influence over production changes. His role supported broader rollout of practices that emphasized eliminating waste (muda), smoothing flow, and building quality into processes. This leadership continuity helped TPS develop as a company-wide system rather than isolated experiments.
Toyota’s Motomachi Plant began operations in August 1959 as Japan’s first production plant dedicated to passenger cars. Building a modern, higher-volume plant raised the stakes for stable flow, standardized work, and efficient internal logistics. Motomachi became a key site for developing and proving TPS practices under growing demand.
Toyota’s “kanban management system” was adopted at all plants in 1963, linking production instructions to actual part usage. This helped make Just-in-Time practical by controlling quantities between processes and reducing excess inventory. As kanban spread, Toyota also addressed supporting needs like work standardization and transport management.
By 1965, Toyota was applying kanban-based retrieval and ordering beyond its own plants, encouraging suppliers to adopt similar techniques. This shift mattered because Just-in-Time depends on reliable external replenishment, not just internal scheduling. The supplier rollout helped TPS become a broader production-and-logistics system across Toyota’s network.
Toyota opened the Takaoka Plant in 1966 as a dedicated Corolla facility, reflecting a push to higher volume with tight cost control. Scaling a popular model increased the need for repeatable, stable processes and strong production management. This expansion created more opportunities to refine TPS tools for consistent output and quality.
In 1970, Taiichi Ohno became a senior managing director at Toyota, signaling that production-system thinking was moving into top leadership. This mattered because TPS depends on management commitment to stop-and-fix problems, standardize work, and continuously improve. The promotion helped institutionalize TPS beyond individual plants and departments.
The 1973 oil crisis increased economic pressure on automakers to control costs and use resources efficiently. TPS principles—especially controlling inventory and eliminating waste—fit this environment well because they aimed to avoid producing more than customers needed. The crisis helped make Toyota’s approach more relevant and influential in the broader auto industry.
In 1975, Taiichi Ohno became an executive vice president, marking how central TPS had become to Toyota’s overall strategy. The 1948–1975 period is commonly treated as the core development window for TPS, when its main pillars—Just-in-Time and jidoka (building in quality by stopping for problems)—were integrated into a coherent system. By this point, TPS was established as a repeatable approach that Toyota could teach and expand.
