Official website Nagasaki Prefecture page

Nagayo Town borders Nagasaki City to the north and faces the southern shore of Omura Bay. It was once a farming area of mandarin orange orchards and rice paddies, but housing estates were built one after another on its hills as it became a commuter town for Nagasaki City. The Siebold Campus of the University of Nagasaki is here.
