The Sustainable Development Goals (SDGs) adopted at the United Nations Summit in September 2015 included water-related goals. However, rainwater is not recognized as an important resource in Japan. To address this issue, “Amamizu Drinks,” which involve a non-routine experience of “drinking rainwater,” were developed as tools for creating awareness regarding rainwater conservation. Additionally, three types of label designs were created, and their effectiveness in developing rainwater awareness was investigated. As a result of the survey, label designs with handwritten illustrations were found to be the most preferred, and the color evaluation was particularly high. Based on these findings, further research is needed to identify the elements required to enhance awareness of rainwater and develop effective environmental education materials as teaching aids. The results of this study can contribute to promoting a sustainable society by encouraging individuals to recognize the value of rainwater as a vital resource.

At the UN Summit held in September 2015, the adopted Sustainable Development Goals (SDGs) included clean water and sanitation. However, public awareness of the importance of rainwater as a water resource is poor in Japan. To ameliorate this situation, "Amamizu Drink," an awareness transformation tool, was used to help people engage in the extraordinary experience of "drinking rainwater." A survey was conducted to investigate the tool’s impact on raising people's awareness of rainwater. The survey results revealed that approximately 70% of the subjects who drank the "Amamizu Drink" showed a tendency to change their attitudes, especially young people in their 20s or younger. The results of this study could be a basis for clarifying the factors necessary to further raise awareness of the importance of rainwater and developing effective environmental education materials for a wider range of age groups.

The people of Akashima Island, located south of the city of Goto in Nagasaki Prefecture, Japan, rely on rainwater for their daily needs. The authors have been building rainwater collection and storage facilities on Akashima Island since the summer of 2017 and have also implemented an environmental education program using these facilities. In addition, the authors have provided support for activities such as the transfer of the facilities and logos constructed by the authors to young migrants who arrived in 2018. As a result of these activities, the project was successful in achieving more than 200% of the crowdfunding goal achieved by the young migrants, and it also resulted in a lot of media exposure, leading to promotion of the remote islands.

This study aims to clarify whether making beverages from rainwater will lead to rainwater utilization. The product names of the beverages to be made were “Amamizu Water,” “Amamizu Cider,” and “Amamizu Soda,” and the label design consisted in a layout of water drops connected in a circle. The label was designed to show the concept of the surprise of drinking rainwater and the circulation of water. The process of making the drinks was filmed using mirrorless and action cameras and edited with YouTube in mind. A questionnaire was sent to those who drank the rainwater beverage to analyze how much their awareness of rainwater had changed. Out of 164 respondents, 111 answered that their image of rainwater had changed, indicating that the rainwater beverage is expected to be effective in promoting rainwater utilization. Further analysis will be conducted to identify the design elements that are important in changing attitudes.
