Japan Meteorological Agency seismic intensity scale
The Japan Meteorological Agency (JMA) Seismic Intensity Scale [1] (known in Japan as the Shindo seismic scale) [2] is a seismic intensity scale used in Japan to categorize the intensity of local ground shaking caused by earthquakes.

The information outlined here is regularly checked at intervals of about five years, and is updated in line with actual phenomena observed in new cases or improvements in the earthquake resistance of buildings and structures.

The Earthquake Early Warning system provides advance announcement of the estimated seismic intensity and expected arrival time of principal motion when an earthquake occurs. These estimations are based on prompt analysis of the quake's focus and magnitude using waveform data obtained from seismographs near the epicenter.
Japan Meteorological Agency magnitude scale - Wikipedia
The Japan Meteorological Agency magnitude scale (Japanese: 気象庁マグニチュード) is a seismic magnitude scale set by the Japan Meteorological Agency. [1] In Japan, for shallow (depth < 60 km) earthquakes within 600 km, the Japanese Meteorological Agency calculates [2] a magnitude labeled MJMA, MJMA, or MJ.
