The Niwa Guest Houses consists a tourist infrastructure placed inside The Niwa Resort. The Guest Houses consisted of autonomous buildings, possibly in the form of bungalows for housing guests visiting The Niwa.
Although never visited during the events of The Medium, the Guest Houses's location is indicated in a map which is placed in the Resort's Central Gate Building. The area used to house a variety of small buildings which were placed near the Niwa's Nature Park and close to the region's lake, in order to bring guests in a closer contact with the nature. It is unclear if this space has been created at the same time with the construction of the main building or afterward in order to correspond to the rising tourist wave.[1]
The Guest Houses's area shows an insignificant role to the events of The Niwa's Massacre and in the history of The Medium. The infrastructure possibly got abandoned and decayed right after the Niwa's Massacre.
