In recent years, severe flood damage has continued in Japan, with 80% of the damage coming from inundation depths of one meter or less (Level-1). Typical recovery costs are over 6 million yen for house repair, and another 3-4 million for home contents. To prevent Level-1 flood damage, we propose a flood-proofing house with measures against inundation, backflow of drainage pipes, submersion of equipment, and buoyancy. The effectiveness of these measures are demonstrated with a full-scale flood test. Some of the inundation and backflow measures can be applied to existing houses, resulting in the reduction and delay of damage.
