We, human beings have kept working hard to have a better life. For instance, in1947, Typhoon Kathleen affected the Kanto area in Japan and caused severe damage. People have recognized the importance of river banks and the need for dams. 7 years later, in 1954, Typhoon Vera, or Isewan Typhoon, occurred, and more than 5,000 people were injured or killed by the disaster. Therefore, the government decided to launch the meteorological satellite ‘Himawari’ into space to get to know the paths of typhoons more accurately.
However, despite the effort that people have made, the damage from the flood never been settled, moreover, we became at risk of the water shortage. Actually, in 2016, the reservoir capacity of dam plummets to a crisis level. Therefore, we were suffering from the serious water shortage.
Immanuel Kant, a German philosopher, said, "We want to be satisfied and live in comfort, but nature throws us into difficulties and labors, not settling for comfort and misspent satisfaction. It teaches us how to overcome trouble, and we learn lessons from that." We have been through ordeals of nature over and over. We have had many failures and sacrifices, nature poses us a greater challenge to solve. From those experiences, many engineers predict what the earth will be like after 50 or 100 years, they try to design the new facilities with the latest high technology. However, life is unpredictable.
In fact, global warming is exceeding our expectations, and the weather conditions bring about drastic changes. It is not the end when we make river improvement facilities such as dams and dikes once. Daily maintenance is also required. Moreover, we need to rebuild them from time to time when they cause environmental changes. Once a facility is being destroyed by unexpected disaster, we will try to restore it with new technology. We never give up and keep moving forward. That is the essence of Japanese-ness.
