In implementing ways of living that take flooding in flood-prone areas into account, it is important to strike a balance between the ease of everyday living and the reduction of flood damage. To gain this knowledge, we focused on the main building of houses with water-filled pits, and examined the characteristics of the height of the main building and water-filled pits by centimeter-level elevation surveys. The results showed that both the water mound and main building had a small variation in elevation in the target area, that the water mound was raised by 3 to 4 meters, while the main building was raised by only half that amount, and that when the difference in elevation between the site and the main building exceeded 1.3 meters, a garden or barn was built to divide the height of the site. In other words, the main building was built at a height that would occasionally be flooded, and the height of the house was carefully set according to how the refuge space called a “Mitsuka”, the living space called a “Moya”, and the work space called a “Naya” and garden were used.
