13 Pointers for Circular Economies from Satoyama Culture

Taku Yamada

More than ten years have passed since COP10 was held in Nagoya and the world was introduced to the concept of satoyama—a unique environment where people and nature coexist in harmony— and the concept seems to be gradually taking root. Elsewhere, the impacts of climate change are becoming more apparent worldwide, and the COVID-19 pandemic has demonstrated the need for society to take a new direction. While the definition of circular economy seems to vary to region, the main concept is that—in contrast to a linear economy (use and dispose) and even reuse—a system where used products and materials disposed in the production process are reproduced into new products, given new value, and then sold again. In many rural regions of Japan, where the satoyama wisdom has been passed down from generations to generations, this circular approach is a core of people’s lives and continues to this day. With rice, for example, the ingredient in Japanese sake and sushi, both of which are becoming increasing popular worldwide, an incredibly efficient cycle has been in place for generations. It is a well-known fact that sake lees, a byproduct of sake brewing, are used to make amazake (a sweet, non-alcoholic sake) and a wide range of pickles including Narazuke. Meanwhile, in the production of daiginjo and other types of sake with high rice polishing ratio, a large amount of rice flour is generated as a byproduct. This rice flour is reused in rice crackers and dumplings. Rice bran is another byproduct of the production process, and in the Hida area of Japan where I live, this has been reused as a kind of wax for polishing the floors and pillars of wooden houses for many years. Further, after the rice bran has been used to care for the home, it is then scattered onto nearby fields, returned to the soil, and reused as fertilizer for new crops. Examples such as these are too numerous to see throughout satoyama areas. Another example can be seen in the use of the kaya grasses used to make thatched roofs, such as those in the UNESCO World Heritage site of Shirakawa-go. Harvested grass is used as snow shelters in the drying process, and then used for thatched roofs after drying. Later, part of the roof that have been damaged by wind and rain is removed and reused as livestock feed. This is then digested by the […]
