We conducted a survey of Shibaura Institute of Technology Kashiwa Junior/ Senior High School students to determine their perceptions of torrential rainfall. We conducted a questionnaire to find out their perceptions of heavy rainfall.

This page shows the results of the survey.

Questions for everyone

Q1.Did you know heavy rain disasters are increasing in recent years?

Surprisingly, we got the result that more than 70% of people know about the increase of heavy rain disasters. That will make clear that many people acknowledge the enlargement of the disasters' scale.

Q2.What countermeasure do you imagine against rain disaster?

Analysis graph of the survey on the countermeasure against the heavy rain disaster

More persons answered the underlying causes, such as global warming and rising seawater temperatures, than those who said the causes were typhoons or fronts, and many proposed countermeasures for secondary damage caused by torrential rains, such as ground investigation and construction of disaster-prevention facilities. I also thought that the respondents' awareness of disaster prevention did not end with measures to deal only with the rain itself.

Q3.What media did you use to know about the disaster?(Only who answered "Know" in Q2)

We found that most people got information about the torrential rain disaster from TV. Next to TV, many respondents obtained information from the Internet. This suggests that more media coverage of torrential rain may raise awareness of disaster prevention.

Q4.What region in Japan do you think rain at most?

The ranking of precipitation in Japan shows Miyazaki Prefecture in first place, Kochi Prefecture in second, Fukui Prefecture in third, Kagoshima Prefecture in fourth, and Ishikawa Prefecture in fifth. The top 10 are ranked in the Kyushu region (5), followed by the Chubu region (4), and the Shikoku region (1), which is almost in line with the results of the survey! This is almost in line with the results of the survey! The survey results are almost in line with the results of the survey! Just for information, Tohoku has a lot of snowfall, but relatively little precipitation.

Q3.What part of the world do you think has most precipitation?

According to the world ranking of precipitation, Colombia (Americas) is in first place, São Tomé and Príncipe (Africa) in second, Papua New Guinea (Asia) in third, Solomon Islands (Asia) in fourth, and Panama (Americas) in fifth. Looking at the top 10, the largest number of countries in the top 10 are from Asia (six), followed by three from the Americas and one from Africa. However, this data is from 2018, so it is not clear if the ranking is similar today, but it is still clear that Asia has by far the largest amount of precipitation. In this survey, too, many people, both those who know about the damage and those who do not, have the impression that there is a lot of rainfall in Asia, which is also consistent with the results of the survey. The next two most frequent countries in the survey were the Americas and Africa. When we look at the top 20, we see that there is not much difference in the amount of precipitation between the Americas and Africa: six countries in the Americas and five countries in Africa.

Q5.Do you know heavy rain can also damage animals and their habitats?

More than 70% of people answered that they do not know about it, indicating that the issue of animal-related damage is still not well known to them. As we learned from the previous question, most people get their information from TV and online news, so reporting on animal damage issues through the media would be a shortcut to increasing awareness.

Question for Who answered "Know" in Q5

What animal did you know for

We found that many people know about the current situation of fish and other creatures living near water. However, few knew about the damage done to livestock and other animals.

Most people know about torrential rain disasters from watching TV, and unless there are more reports on TV about the damage to living creatures caused by torrential rain disasters, few people will remain aware of this issue. However, I felt that many people, both those who know about torrential rain disasters and those who do not, are aware of the seriousness of torrential rain disasters because they know that the Kyushu region has the most rainfall ,they see their own region as the most serious in comparison with other countries. The current situation is that there are still people who do not know about the torrential rains. What can we do to change this situation and reduce the damage?
