This study conducted gelogical survey in the Nagato tectonic belt, Yamaguchi and zircon U–Pb dating for metamorphic and plutonic rocks from the Nagato tectonic belt. The results indicated the geological, petrographical and geochronological characteristics of the Nagato tetonic belt quite resemble those of the Kurosegawa tectonic belt.
