Since the Heian period, nature has permeated every aspect of Japanese culture. The Japanese literally eat, sleep and wear the seasons – from kimono motifs to seasonal sweets and annual festivals. This celebration of nature leads to a deep awareness of the seasons, called kisetsukan. Through 12 key concepts, such as shun (focusing on eating seasonally), Kasane (the language of colour), and mottainai (zero-waste living), this treasure trove of folktales, recipes and activities is an invitation to mark and appreciate each passing season.
