The Transition to Minamishimabara
For many years, Kazusa operated as an independent municipality. However, on March 31, 2006, a significant administrative restructuring took place. Kazusa merged with seven other towns from the Minamitakaki District—Arie, Fukae, Futsu, Kitaarima, Kuchinotsu, Minamiarima, and Nishiarie—to officially establish the city of Minamishimabara.
This merger consolidated several smaller communities into a single urban entity to streamline governance and regional development.

Tourism and Natural Attractions
One of the most distinctive features of the Kazusa area is its relationship with marine life. The waters around Tsuuji shima are home to a resident population of dolphins. This natural phenomenon has made the area a destination for dolphin watching, which serves as a primary driver for local tourism and provides visitors with a unique glimpse into the region's biodiversity.
