We experienced the Great East Japan Earthquake. After that we have been working on activity to collect every record (data) by an industrial-academic-government cooperation. I introduce significance and importance to collect earthquake disaster records with a process to date. We utilize VR (Virtual Reality) and MR (Mixed Reality) and display earthquake disaster remains of structures in size of the original. For a possible great earthquake disaster, I will submit how I should utilize an IT technology for the importance of learning, future disaster prevention education from a past record in future.
