THE SECOND AID is a disaster kit that is jointly developed with the disaster design wiki OLIVE that we operate, together with the people affected by the Great East Japan Earthquake. The kit was designed based on the experience from the actual disaster, containing minimum items and useful information necessary to survive the first 72 hours after a disaster happens. When putting a disaster kit in the back of the shelf in your house, it cannot be easily found when in need at a time of disaster. Therefore the kit is designed to be put in a bookshelf. It looks simple, which fits in living space.
