Japan’s premodern concept of nature at root of distinctive mindset in early childhood education

A new study reveals that Japan's traditional concept of nature, dating back to the premodern era, shapes the country's early childhood education philosophy. This approach emphasizes a balance between self-guided action and entrusting oneself to external forces, guided by principles similar to Sozo Kurahashi's 'yūdō' theory.
