Yui is well known for the local sakuraebi which transates as cherry shrimp with cherry referring to the colour. Yui's flag displays the character "由" to represent the town and 12 stamens; one for each of the wards. These are contained within orange blossoms, a special product of Yui. Around the flower, a seagull represents peace and equality. Yui's symbols are the bush warbler, fragrant olive, and cherry blossoms.
In Yui, some woodblock prints drawn by Utagawa Hiroshige are in the Hiroshige Museum. The town has two elementary schools and one junior high school. Yui is served by Yui Station on the Tōkaidō Main Line.
