[1] A nagaya was a long housing complex under the same ridge, one or two stories high, divided into small compartments for rent.
[1] Historically, similar houses were built around a rich manor or castle for low-ranking samurai.
At the ends of the building shops were located, typically, their owners living in adjacent rooms.
Nagaya were also known as yakeya (焼け家, burning house), due to their tendency to catch fire.
[4] If a gateway was located in one section, that structure was called a nagayamon (長屋門, longhouse-gate).
