I liked historical Jinaimachi in Tondayabashi. This is about 30 minutes by train from Osaka central. This Edo-period town is full of old wooden buildings and small shops here and there. Originally a temple town (Koshoji Betsuin Temple of the Ikko sect of Buddhism), it developed into a rural trade town in the 17th century. The old mansions, earthen walls and yojinbori (drains used for fire prevention) have been preserved by the national government. There only about 500 town houses in this little town and about 250 of it are traditional houses.
