About us

Launched in 2005 following the 1995 Great Hanshin-Awaji Earthquake, the facility enables detailed studies of the destruction mechanisms of full-scale structures and the damage to building interiors by reproducing actual earthquake motions.

To contribute to understanding and improving the continuity of socio-economic activities, we engage in the research and development of a set of technologies to evaluate potential and future risks in preparation for large earthquakes and subsequent earthquakes.

Toward structures that never collapse

  • Demonstration experiments: Reproducing actual earthquake motions and actually destroying full-scale structures.
  • Clarification of the destruction process: Reproducing and tracking how structures break, and understanding the mechanisms of destruction through data analysis.
  • Developing reliable technologies: Developing technologies to prevent destruction and damage, based on scientific and proven evidence.
