The history and developments of strong-motion observation in Japan are reviewed. A special attention is paid to the recent developments of instruments and nation-wide observation networks. After the 1995 Hyogoken Nanbu earthquake, thousands of strong-motion seismographs and seismic intensity meters were installed all over Japan. Summary of those networks and the latest strong-motion seismographs are described. The future developments for desirable strong-motion observation are also discussed.
