Japan has suffered serious damage in terms of infrastructures and human resources around the Pacific coastal area in Tohoku district due to the Great East Japan Earthquake and Tsunami that occurred on March 11, 2011. In this situation, many politicians and key figures appeal for connecting restoration of this damage with overall revival in Japan, and the current administration is also going to follow their policy. However, the current political situation in Japan is weak so that continuous reform is not possible. Therefore it is doubted whether the administration can propose a dynamic concept and strategy for the overall revival in Japan. In this report, I propose a framework to lead a design and/or a strategy that can overcome political weakness and would like to contribute to the drafting of the policy that can carry out continuous revival.

Multiplier effects are expected with such a public policy as to lead the private sector to continue paying in a long term for costs against disasters without withdrawal from bank accounts with strict economy. Since disaster risk-off will not last long, it is necessary to elaborate so that the private sector continues to pay for the costs even at succeeding risk-on. Such a policy would have an option of mitigation of one-pole concentration into Greater Tokyo, namely risk diversion toward the Japanese frontiers.

The huge tsunami caused by large-scale earthquake like East Japan Earthquake usually happens once in several hundred years. As the damage by the tsunami was vast, Town planning considering to endure most unusual large scale tsunami is inevitable. As almost all the concrete buildings were not destroyed by the earthquake and the structure of concrete buildings remained after tsunami attack, the best way is to build tall buildings as many as possible in the seashore lowland area. Tall buildings may be the evacuation points and protect household goods from tsunami. Re-building along this policy is very difficult, but it will save people in far-off future from miserable tragedy.

The use of chemical fertilizers and pesticides in the name of scientific and technological progress in agriculture, which is so called "conventional agriculture", has led to an expansion of productivity and labor saving on the part of producers within a short period of time, but overuse has caused serious environmental deterioration, viz., soil depletion and water pollution. The overall production has actually led to a decrease of the volume of production and adverse effects on the human body.
In response to this, an environmental-preservation type of agriculture, or "cycloid" agriculture, has been revived and has emerged as an alternative to the conventional agricultural method. The cyclical method primarily utilizes botanical organisms in the natural ecology, viz., it calls for the revitalization of more traditional methods of agricultural production.
In the environmental-preservation•cycloid method, a symbiosis between agricultural production and the natural ecology is essential. To realize this, rigid observation, keen insight, and, quite often, manual labor are recognized as key factors in the success of agricultural production.
However, the productivity of this method is generally less, or much less especially during the shift time from the conventional agriculture to the cycloid one. Consequently, agricultural producers struggle to manage their farming businesses. As a result, it is very difficult to increase the number of producers who will commit to this method, in spite of the fact that its advantages to the environment as well as to lives of living creatures are widely recognized. Therefore, in order to promote cycloid agriculture, it is imperative to present successful business models of it
This study covers three specific types of cycloid farming methods: two types involving rice producers and one type of vegetable producer.

Prospects for the Pacific Rim renewable energy economic area are discussed, for using renewable energies to recycle resources and reduce environmental impact by developing a series of technologies which will three-dimensionally use the ocean providing a field having a pressure range from the normal pressure to a high-pressure in the deep sea, as the ambient pressure.
