It is the current-conditions half of Japan's Economy Watchers Survey, run by the Cabinet Office. It asks 2,050 purposively chosen watchers whether conditions improved or worsened versus 3 months ago. Watchers are frontline observers in household, corporate, and employment roles across 12 regions, not random consumers or managers. Running monthly since the January 2000 survey, its headline is a DI, a diffusion index from 0 to 100 for the direction of change.
