The name derives from when there once was a vinegar maker at the foot of the slope. The Slope of Suya no Saka is built to mirror that of Shioya no Saka (the Slope at the Salt Maker) in Minamidai, as the whole town of Kitsuki is developed to mirror within itself between the two hillside regions in the north and the south. Samurai residential districts resided on the both hilltops, while the merchants and townhouses occupied the lower region.
This hilly strip of road features beautiful stone pavement with mud walls and stone walls in unison. There once was an open space at the top of the hill for assembling horsemen and warriors.
