Munewari nagaya (A split row house)

A nagaya is a house that divides one large building into several rows. Things that take the shape of the divided rooms inside of the large building from the front to back were called Munewari nagaya (partitioned housing structures). The roof was made of thin shingles and the partitioned walls were also thin. Because almost all of the materials used in the construction of these structures were either wood or paper, these wooden buildings were also called yakeya (fire houses) because they are very susceptible to fires. Many of the common people rented and lived in these types of rooms that were located in the small area that comprised approximately 20% of the ancient city of Edo.
