Tadaoka has developed into a close community of residents who are known for their friendliness. There is a strong bond within the community; everyone is said to know and look out for other, to the point where it is even acceptable to scold neighboring children should they do something naughty. Speaking of children, the town only has two elementary schools and one junior high school. Students in the area commute to high schools in neighboring towns. The smallest part of the smallest town in Japan is a 900-meter-long section of road. This narrow road can be traversed by car in under a minute, a real blink-and-you-miss-it way to get through Tadaoka.
The town hosts its eponymous Tadaoka Danjiri Festival every October. It is a festival that started in the Edo period (1603-1868) to pray for bountiful harvests and safety, during which floats called danjiri are showcased from four neighborhoods within the town. They are believed to host Shinto gods from local shrines, and are paraded through the town. Compared to the famous Kishiwada Danjiri Festival, the Tadaoka Festival is a more restrained version, mostly attended by members of the local community. This means that the festival is less crowded, and visitors can get up close and personal with the highly decorative floats to admire the local craftsmanship.
