Additional Note: Reasons for the Connection Between Climate and Culture
- In Japan, agricultural culture, nature worship, and Shinto are foundational, leading to the development of ceremonies of gratitude and prayer in line with seasonal changes.
- Moreover, the aesthetic sense of "enjoying the seasons" is rooted in daily life, including cuisine, clothing, and travel.
Japan's characteristic of finely sensing changes in nature and elevating them into seasonal events reflects a culture that deeply intertwines with climate, living on in the daily lives and values of the Japanese people.
