During the Sengoku period, a time of constant war and uprisings, Tondabayashi was a religious autonomous city, surrounded by earthen walls and moats, centered around the Ikko sect's Koshoji Betsuin temple. The original town consisted of six streets and seven blocks, roughly 400 meters east to west and 350 meters north to south, with four wooden gates on its perimeter. These gates were closed at night to maintain public order. The neat, orderly layout remains almost intact, with the remains of the earthen walls and moats still visible, evoking a glimpse of times long past. Shironomon-suji, which runs north to south through the center of the town, currently has approximately 600 townhouses, of which approximately 250 remain traditional, exuding history and elegance. The former Sugiyama Residence, located in the southwest of town, is a nationally designated Important Cultural Property, while the Nakamura Residence is a prefecturally designated Tangible Cultural Property. The entire area is designated as a Nationally Important Preservation District for Groups of Traditional Buildings.
