The Goto Islands in the East China Sea, comprise over 140 islands. The priest Kukai, who was among envoys to China during the Tang Dynasty and brought esoteric Buddhism to Japan, stopped here first when he returned from his journey. The Goto Islands are also known for the underground Christians who maintained their faith throughout a long period of persecution. The influence of diverse cultures has formed a unique architectural landscape and way of life. Most tourists visit the Kamigoto area (mainly on Nakadori Island) and Fukue Island.
