Feudal period The area had been famous for its ceramics production since at least the
Kamakura period.
Early modern period During the
Edo period, the area of modern Seto was controlled by the
Owari Tokugawa of
Owari Domain.
Late modern period During the
Meiji period, Seto village was organized in 1888 with the establishment of the modern municipalities system, becoming a town in 1892. After annexing the neighboring village of Akatsu in 1925, Seto was raised to city status on October 1, 1929. Much of the city was destroyed by air raids in 1945 during World War II.
Contemporary history In the postwar period, the city grew as a
bedroom community for Nagoya and as a tourist designation. On March 25, 2005,
Expo 2005 opened with its main site being in
Nagakute and additional activity in Seto. The expo continued until September 25, 2005. ==Government==
