CORE DEFINITION

Dan: refuse what is not needed. Sha: dispose of what is owned but useless. Ri: let go of attachment to material desires.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Subtractive living. Counter consumerism and information overload; space and attention are scarce resources, and clearing allows flow.

anchor

Anchor fast decisions

Hideko Yamashita proposed organizing items and mind through 'dan' (not buying), 'sha' (discarding), and 'ri' (detaching from attachment), returning to simplicity. It is a dual reduction of material and psychological burden.
