Geodesy.
Extended from Japan to Korea in 1898. In Japan, replaced by Tokyo 1918 (CRS code 4301). In South Korea replaced by Tokyo 1918 only for geodetic applications; for all other purposes replaced by Korean 1985 (code 4162).
Japan - onshore; North Korea - onshore; South Korea - onshore.
Ellipsoidal 2D CS. Axes: latitude, longitude. Orientations: north, east. UoM: degree
