During the Sengoku period, a time of constant war and uprisings, Tondabayashi was a religiously autonomous city with earthen walls and a moat centered around the Ikko sect's Koshoji Temple branch. The town was originally called Rokusuji Nanacho, and Kido gates were set up at four locations around the perimeter, approximately 400 meters from east to west and 350 meters from north to south, and the gates were closed at night to maintain public order. Today, the neatly organized sections of the past remain almost exactly as they were, and the partially preserved remains of the earthen walls and the guard moat remind us of the distant past. Jonomon-suji, which runs north-south through the center of the city, currently has about 600 townhouses, of which about 250 remain traditional houses, giving it a sense of history and style. The ``Old Sugiyama Family Residence'', which stands in the southwest of the town, is a nationally designated important cultural property, and the ``Nakamura Family Residence'' is a prefecture-designated tangible cultural property. The entire area is designated as a nationally important preservation district for groups of traditional buildings.
