It is the easiest way to download the strong-motion data.
Data of quick report
You can download the strong-motion data of quick report; unauthorized raw data received from the recorders immediately after an earthquake. You can also see site-distribution maps here.
Select an earthquake and Download data
You can select an earthquake record from monthly earthquake list. Use this link if you know the origin time of an earthquake and want to download its data. You can also view and download a hypocentral map here.
Search for earthquake and download data
You can search for earthquakes by the origin time, magnitude, epicenter location, etc.
Search and download data
You can search for Strong-Motion data independent of earthquakes, based on date and time, site location, site characteristics, maximum acceleration, epicentral distance, etc. The data can be compressed into a single tar file.
Velocity Response Spectrum Download
Select a velocity response spectrum file and download it.
You can download utility program for K-NET data.

K-NET is an observation network composed with about 1000 broadband strong-motion seismographs, with a dynamic range up to acceleration of 4000 cm/sec/sec, deployed 25km intervals in nationwide of Japan. The observed data and peak distribution maps are available as soon as an earthquake happened, and you can download the data not manually checked.
As the fundamental activities of the Headquarters for Earthquake Research Promotion, Japan, the high sensitivity seismograph(Hi-net) and the strong-motion seismograph(KiK-net) across the all of Japan, have been deployed after the 1995 Kobe earthquake, by National Research Institute for Earth Science and Disaster Resilience (NIED).Each site of the KiK-net is composed of a pair of strong-motion seismographs installed at the well bottom, which is the same location as the Hi-net sensors, and on the ground surface. Observed wave data, distribution map of peak acceleration, etc., are available to the public.
The Hi-net is an observation network composed of about 800 high-sensitivity seismographs deployed nationwide. The sensors were installed at a bottom of the borehole down to more than 100m depth. The Hi-net is capable even detecting seismic motions that are too weak to be felt.
The F-net is an observation network composed of broadband seismographs deployed at approximately 70 locations nationwide. The F-net is capable of accurately detecting slow ground motions originating from remote seismic sources.
The National Seismic Hazard Maps for Japan and data download is available.
