A catalog of earthquakes of magnitude 6 or more felt in Japan and smaller earthquakes which caused damage in Japan from 1885 through 1980 is presented. The catalog also contains unfelt earthquakes of M≧6 which occurred in the vicinity of Japan (region A indicated in the map), but the listing of unfelt earthquakes may be incomplete for the years before 1924. The catalog is incomplete for deep earthquakes before 1900. The main sources of materials are Utsu's catalog of 1979 (revised in 1982) for 1885-1925, the new JMA catalog (1982) for 1926-1960, and the JMA Seismological Bulletin for 1961-1980. Gutenberg-Richter's catalog (1954), ISS, or ISC Bulletins are used for focal coordinates of earthquakes occurring outside of the network of JMA stations. For some earthquakes the author has determined the focal coordinates or magnitudes. Statistical analyses of the catalog and studies of seismicity patterns in relation to the occurrence of great earthquakes will be published elsewhere.
