Act on the Promotion of Tsunami Countermeasures (Any data that the title of a law indicates to be a "Tentative translation" has not yet been proofread or corrected by a native English speaker or legal translation expert; this data may be revised in the future.Tentative translation)
Act No. 77 of June 24, 2011
As made clear by the Great East Japan Earthquake on March 11, 2011, a tsunami is a disaster that, once it occurs, can cause enormous damage to the lives, bodies, and properties of citizens over a wide area and have a serious impact on the sound development of Japan's economy and society. It is a profound regret that Japan has suffered tremendous damage from tsunamis on multiple occasions in the past, and that so many precious lives were lost in the Great East Japan Earthquake. Furthermore, the Great East Japan Earthquake has significantly affected the lives of local residents and the economy and society of Japan due to the disaster caused by the accident at a nuclear power plant.
At the same time, even if a tsunami has occurred, the damage to human lives can be considerably mitigated if citizens take prompt and appropriate action. Therefore, it is particularly important to deepen citizens' understanding of and concern about tsunamis, the characteristics of tsunami damage, and the need to prepare for tsunamis. This has become even more important following the unprecedented catastrophe brought about by the Great East Japan Earthquake.
Japan is located on the boundaries of tectonic plates and their vicinities and is constantly exposed to the danger of being damaged by large-scale earthquakes and accompanying tsunamis. In order to keep the devastation caused by the Great East Japan Earthquake, which claimed so many lives, from repeating itself, the national government must frankly reflect on the fact that past tsunami countermeasures were not necessarily sufficient and take all possible measures to counter tsunamis, taking into account the latest knowledge on tsunamis, ancestors' wisdom and actions, and other historical lessons.
This Act is hereby enacted to clarify basic understanding of tsunamis and to comprehensively and effectively promote tsunami countermeasures.
(Purpose)
Article 1In order to protect the lives, bodies, and properties of citizens from damage caused by tsunamis, this Act clarifies basic understanding in promoting tsunami countermeasures and, at the same time, provides for matters necessary to strengthen tsunami observation systems, promote tsunami-related research studies, implement education and training necessary for tsunami-related disaster risk reduction, and develop facilities for tsunami countermeasures as well as other matters necessary to promote tsunami countermeasures, thereby comprehensively and effectively promoting tsunami countermeasures and, in doing so, contributing to the maintenance of social order and the securing of public welfare.
(Basic Understanding in Promoting Tsunami Countermeasures)
Article 2Tsunami countermeasures must be promoted comprehensively and effectively based on the following basic understanding of tsunamis:
(i)once a tsunami occurs, it can cause enormous damage to the lives, bodies, and properties of citizens over a wide area and have a serious impact on the sound development of Japan's economy and society.
(ii)the damage to human lives caused by tsunamis can be significantly mitigated if citizens take prompt and appropriate action upon their occurrence. Therefore, it is particularly important to promote the development of facilities for protection against tsunamis, such as seawalls and floodgates; promote the steady development of tsunami evacuation facilities (sturdy buildings or structures to function as temporary evacuation sites in areas presumed to be inundated by tsunamis; the same applies hereinafter); promote the implementation of education and training necessary for tsunami-related disaster risk reduction; and promote the dissemination of thinking on disaster risk reduction, thereby enhancing citizens' understanding and concern about the characteristics of tsunamis, the nature of their impact, and the need for preparedness against them;
(iii)it is necessary to promptly and appropriately forecast the scale of tsunamis to prevent or mitigate their damage. Detailed forecasts of their damage remain difficult. Therefore, it is important to improve tsunami observation systems, and, promote research studies on tsunamis that occurred in the past, those that are predicted to occur in the future, and the damage caused by them;
(iv)a tsunami has the characteristic of spreading over a wide area beyond national borders, and it is highly necessary to internationally share the results of research studies in each country. Therefore, it is important to promote international cooperation in observation and research studies.
(Implementation of Tsunami Countermeasures Based on the Purpose and Contents of This Act)
Article 3(1)In implementing disaster countermeasures based on the Basic Act on Disaster Management (Act No. 223 of 1961), the Special Measures Law on Earthquake Disaster Prevention (Act No. 111 of 1995), and other related laws, the national and local governments must appropriately implement tsunami countermeasures based on the purpose and contents of this Act.
(2)Business operators and citizens must deepen their understanding of and concern about the importance of tsunami countermeasures and endeavor to cooperate with tsunami countermeasures conducted by the national and local governments.

These forecasts must be made for each tsunami scale, taking into account the status of facilities for countering tsunamis.
(2)Prefectures and municipalities must endeavor to appropriately review the contents of the forecasts prescribed in the preceding paragraph, taking into account changes in current land use conditions in areas that may be inundated by tsunamis and the latest knowledge on tsunamis.
(3)The national government must endeavor to provide information, technical advice, and other necessary support to prefectures and municipalities so that they can properly conduct the forecasts prescribed in paragraph (1) and utilize the results thereof in tsunami countermeasures.
(Implementation of Education and Training Necessary for Tsunami-related Disaster Risk Reduction)
Article 7Taking into account the results of the research studies prescribed in Article 5, paragraph (2), the national and local governments must endeavor to enable citizens to acquire the latest knowledge on tsunamis, understand potential tsunami damage in their areas, and know how to take prompt and appropriate action in the event of a tsunami, utilizing effective methods, including the use of video images in school education and other various opportunities, to provide citizens with education and training necessary for tsunami-related disaster risk reduction and promote the dissemination of thinking on disaster risk reduction.
(Dissemination of Information regarding Potential Tsunami Damage in Each Area)
Article 8(1)In disseminating information to residents on the tsunami inundation zone and depth pursuant to Article 14, paragraphs (1) and (2) of the Special Measures Law on Earthquake Disaster Prevention, prefectures and municipalities must utilize the results of the forecasts prescribed in Article 6, paragraph (1) and endeavor to do so more effectively by distributing printed materials and having residents view images of projected damage.
(2)If there are underground shopping malls or other facilities in underground areas within the presumed tsunami inundation zone that are used by a large number of unspecified individuals, or, facilities that are used primarily by the elderly, persons with disabilities, infants, or others requiring particular consideration in terms of disaster risk reduction and it is deemed necessary to ensure their prompt and appropriate evacuation in case of a tsunami, prefectures and municipalities shall give special consideration to disseminating the information prescribed in the preceding paragraph to the owners or administrators of those facilities.

(v)promotion of the designation of tsunami evacuation facilities;
(vi)promotion of the development of tsunami evacuation facilities and evacuation routes to them according to area characteristics.
(2)When the national and local governments intend to construct public facilities (excluding those constructed for the direct purpose of protection against tsunamis) in areas that may be inundated by tsunamis, they must give due consideration to providing them with a temporary evacuation site function and other tsunami-related disaster risk reduction functions in those areas.
