Sannai-Maruyama Longhouse
description: The largest of its kind, the building is a longhouse measured to be 32 meters in length and 9.8 meters in width, with a floor area of approximately 250 square meters. It takes an oval shape on a pitted floor. Its internal structure or skeleton consists of wood pillars, likely made from chestnut, a feature that can be found in surrounding buildings within the community. By modern standards, the longhouse's aesthetics could be described as primitive. The exterior is naturalistic, showcasing the raw materials used in its construction. Specifically, supported by the pillars is a thatched roof. As the building is slightly underground, there are stair entrances on each length of the structure; for modern accessibility, a ramped entrance is also provided. The entrances are defined by their doors, propped open from bottom to top, made of a similar material to the exterior. The building is a modern model of prehistoric, Jomon-era architecture and culture. Since the building’s recreation and opening in 1995, it has been primarily used for public education, with the site's connections to the Jomon Jiyukan (a nearby museum). In its time period, however, the original building was likely a communal space. As Jomon society became increasingly sedentary, communities such as those surrounding the structure developed. Its large size allowed these communities to gather.
