Giravanz is the local soccer team in Kitakyushu that lay at the stadium in Kokura. Their mascot is a seagull named Wavy.
Matsu Beach is on a long sweeping bay in Okagaki Town in the Onga District. It is known for a long cycle path through the pines that grow along the beach.
Tagawa was a former coal-mining town whose two remaining brick chimneys are symbols of the town.
