Nioza Historical Road
Nioza is the old district of the former castle town of Usuki in Oita. One of the narrow lanes is stone paved and winds around a slope.
Sometimes called a samurai district, there are a few samurai homes, but also a lot of temples and merchant quarters.
One of the former temples has been converted into a "rest area" for visitors and puts on seasonal displays. When I as there it was dolls.
If you are in Usuki it is certainly worth a look see, but not worth making a special journey.
