Cadastre, engineering survey, topographic mapping (large and medium scale).
Although legally defined as Tokyo datum the accuracy of the geodetic connection to mainland Japan is low. Replaced by JGD2000 / Japan Plane Rectangular CS XIV (code 2456) from April 2002.
Japan - onshore - Tokyo-to south of 28°N and between 140°30'E and 143°E.
Cartesian 2D CS. Axes: northing, easting (X,Y). Orientations: north, east. UoM: m.
