Yokkaichi, located in northern Mie Prefecture, is blessed with a good natural harbour and prospered as an inn town during the Edo period. The name of the city derives from the fact that the market stood on days with the number '4'.
After the war, an industrial complex was formed around the port of Yokkaichi, and in recent years the city has developed into the largest and most populous town in Mie Prefecture with a diverse range of companies. The complex is transformed into a fantastic look at night by the light effects, attracting attention from fans of night views of factories.
