The city of Seto is famous for its pottery and ceramics, so much so that the generic word for ceramics in Japanese is setomono (瀬戸物). The main street along the river is lined with dozens of pottery shops. Every third Saturday and Sunday in September, there is a very large pottery festival called Setomono Matsuri[2](瀬戸物祭り) This festival attracts about 20,000 visitors from around Japan and abroad every year.[citation needed]


The city has a climate characterized by hot and humid summers, and relatively mild winters (Köppen climate classification Cfa). The average annual temperature in Seto is 14.8 °C. The average annual rainfall is 1810 mm with September as the wettest month. The temperatures are highest on average in August, at around 27.3 °C, and lowest in January, at around 3.1 °C.[3]
