Sophia University has released the results of the Sophia University Climate Survey 2025, a nationwide online study examining public perceptions, knowledge, emotional responses, and daily behaviors related to climate change. The research was conducted by a team led by Professor Carola Hommerich (Principal Investigator) from the Department of Sociology, Faculty of Human Sciences.
The survey was carried out from August 27 to September 1, 2025, and collected valid responses from 5,000 individuals aged 15 to 74 across Japan.
As the impacts of climate change become increasingly visible in Japanese society and the need for effective countermeasures grows, this survey provides a comprehensive assessment of how people understand and respond to climate-related issues. The report also presents results by age group, offering valuable insights into generational differences in concern, awareness, and behavior.

Comment from the Principal Investigator Professor Hommerich stated:
“The results indicate that concern and anxiety about climate change are widespread. However, these feelings do not necessarily translate into knowledge or action. Among younger generations in particular, emotional impact does not always appear to be strongly connected to understanding or behavioral engagement. Going forward, it will be important to examine the social and psychological factors underlying this gap with careful attention.”
