Ten years have passed since the 2011 Great East Japan Earthquake. On this occasion, the NHK Broadcasting Culture Research Institute organized a symposium, where the utilization and sustainability of disaster digital archives was discussed by experts from a university, the Ministry of Education, Culture, Sports, Science and Technology MEXT), a commercial broadcaster, and NHK. The report and discussion included the following.
– The number of archives linked to “HINAGIKU” National Diet Library Great East Japan Archive—a portal site for records and data of the earthquake disasters—has increased from the initial 21 to 53. Some archives, however, choose not to be linked for the reason that the system is too complicated. In addition to this, “HINAGIKU” initially had a map function but had to remove it due to budgetary reasons, which is hindering the use of this portal site for disaster education and reconstruction tourism.
– Utilization for disaster education: following the MEXT's new Course of Study emphasizes “Ikiru Chikara” (“zest for living,” or power to survive), Iwate Prefecture started disaster reconstruction education utilizing archives. Disaster archives expected to be used in Geography, which will become a compulsory subject in high schools nationwide from 2022. On the other hand, disaster images may trigger mental stress. Therefore, it is important to provide opportunities for students to enhance their “literacy and empathy” by letting them to think why they are viewing those images and to exchange their impressions.
– A move to connecting digital archives and real worlds is progressing, represented by Asahi Broadcasting Corporation's virtual tour of the 1995 Great Hanshin-Awaji Earthquake utilizing map function and NHK's digital archive presenting the real disaster-related exhibition in virtual reality. Meanwhile, the cost of maintenance is a big challenge. One broadcaster launched its archive supported by Google. Many are trying to find solutions, arguing, that archives should be operated by Japan Commercial Broadcasters Association (JBA), the national government, Japanese society as a whole, etc. Disaster data and materials are intellectual property of the nation as well as the “investment for the future” for passing down disaster lessons, protecting life, and creating a sustainable society. The panel suggested that 3/11 should be commemorated as “Disaster Education and Passing Down Disaster Lessons Day.”
