A practical lesson using tsunami deposits along the coast of Iwate prefecture is reviewed, as well as a practical lesson using tsunami deposits in schools. How they should be used in the future is examined. Noda Village Noda's event layer is stripped off to prepare specimens, and practical training is conducted to determine the cycle of tsunamis associated with trench-type earthquakes. Evacuation behavior is examined and efforts are made to raise awareness of disaster prevention related to tsunamis. Descriptions related to the tsunami narrative have appeared in textbooks since the Tohoku-Pacific Ocean Earthquake, and are repeatedly studied in elementary schools, junior high schools, and high schools. Classes utilizing tsunami deposits distributed in Aramakihama, Miyako City are conducted in collaboration with junior high schools, high schools, the government, and Sanriku Geopark. Historical earthquakes and tsunamis are identified, and tsunami inundation areas and evacuation behavior are verified. It is confirmed that 93.7% of students have improved awareness. It is hoped that improving the accuracy of tsunami deposit certification not only in lowlands but also in small valleys and hills will strengthen descriptions of tsunami in textbooks and increase the number of practical lessons.
