Welcome to the Building Research Institute (BRI) strong motion network website. We have been conducting strong motion observation for building structures since 1957.

Currently, we are operating more than eighteen strong motion stations deploying in major cities throughout Japan. One third of the stations are placed in Tokyo metropolitan area and its outskirts.

This web site provides recent strong motion data and information related to the strong motion observation.
