Learning from the 1995 Hanshin-Awaji Earthquake, Tokyo Metropolitan Government has been preparing the restoration and reconstruction measures from a huge amount of damages caused by next Tokyo Earthquake. We are developing the methodology of earthquake restoration exercise with local government and residents according to TMG's restoration measures. In this paper, such unique trials of pre-disaster restoration measures in Tokyo are introduced and evaluated.

The Niigata Ken Chuetsu earthquake struck a mostly rural and mountainous part of Niigata prefecture in Japan. Forty-eight people died, and 551 were severely injured. Over 100,000 people required emergency shelter, and nearly 3,500 households are living in temporary housing. The prefecture government has estimated earthquake damages at 3 trillion yen (about $30 billion), and at least 1,000 workers lost their jobs. The primary issues involve lack of access to rural settlements because of landslides, effects on elderly populations, and the long-term effects on the agricultural economy and lifestyle of the region. Because of extensive landsliding, many communities will also have to face difficult decisions regarding possible relocation or abandonment of their village sites. Based on the experiences of other earthquakes, it is clear that this process will take many years to resolve, and that much of the region will be permanently changed by this earthquake.

This treatise outlines developments in disaster management focusing on earthquake disaster measures taken by the Japanese and Tokyo Metropolitan Governments since the 1980s. The 1978 Large-Scale Earthquake Measures Special Act on conditions for predicting the Tokai Earthquake significantly changed the direction of earthquake disaster measures in Japan. The Tokyo Metropolitan Government undertook its own earthquake disaster measures based on lessons learned from the 1964 Niigata Earthquake. In the 1980s, it began planning urban development disaster management programs for upgrading areas with high wooden houses concentration - still a big problem in many urban areas of Japan - which are most vulnerable to earthquake disasters. The 1995 Great Hanshin-Awaji Earthquake in Kobe brought meaningful insight into both to earthquake disaster measures by the Japanese Government and by the Tokyo Metropolitan Government and other local governments nationwide. Long-term predictions concerning possible earthquake occurrence have been conducted throughout Japan and new earthquake disaster measures have been adopted based on this long-term prediction. The Tokyo Government has further completely revised its own earthquake disaster measures. As a review of measures against foreseeable earthquake disasters based on developments in disaster management measures, this treatise provides invaluable insights emphasizing urban earthquake disaster prevention developed in Japan over the last 30 years that readers are sure to find both interesting and informative in their own work.
