What does a mountain town in eastern Japan, a city in northern Hungary known for its wine and historic castle and the city of Gainesville have in common? These three cities with vastly different histories located in far flung regions of the world agreed to share their culture, government and economies with each other through a sister-city relationship. “The idea behind the program is that the cities share information about who they are, where they are located and their economic development, and to see if there is a way to share economic success,” said Catiel Felts, Gainesville’s director of communications and tourism.
