Kosai is located in the far southwest corner of Shizuoka Prefecture, bordered by Aichi Prefecture to the west, Lake Hamana to the east. The name of the city means "west of the lake", in reference to its location near Lake Hamana. The city is bordered to the south by the Enshū Gulf of Pacific Ocean. Due to its location, the warm Kuroshio Current offshore provides for a temperate maritime climate with hot, humid summers and mild, cool winters.
During the Edo period, Kosai was tenryō territory administered directly by the Tokugawa shogunate, and the location of a barrier gate regulating traffic on the old Tōkaidō highway connecting Edo with Kyoto. A post station named Shirasuka-juku developed near the barrier, and this was the forerunner of modern Kosai. During the cadastral reform of the early Meiji period in 1889, the area was reorganized into five villages within Hamana District, Shizuoka. Four of these villages (Washizu, Iride, Shirasuka, Chibata) merged to form the city of Kosai on January 1, 1972.
The economy of Kosai is dominated by light manufacturing of automobile components and electronics, as well as commercial fishing. Kosai is home to Suzuki Motor Corporation's Kosai Assembly Plant, Suzuki's main domestic production plant as well as to plants owned by Panasonic and Sony.
