Following the approval of a law by the Diet to integrate two airports (Kansai and Itami), an issue of integrating three airports (including Kobe) in Kansai has been advanced towards a solution. The aim of the law is improvement of the Kansai International Airport's performance, and fulfilling its expected role through the integration of the two airports. However, there is concern that the issue of integrating three airports cannot be solved if demand is not expanded significantly. It is therefore important, in the first stage, to review the impacts of the law that relies on PFI scheme to integrate two airports. Possible integration of three airports should be considered only in the next stage. Further, there may be many legal complications to include Kobe airport as the goal of such integration is to optimize the utilization of three airports in Kansai. As for execution by Union of Kansai Governments, it is similar. Under such circumstances, this paper points out key issues through legislative analysis.

The sizes of bulk carriers have been getting larger and larger. In Japan, international bulk strategic ports have been already selected, and will be developed hereafter. But, because of the Great East Japan Earthquake disaster, some delay of this development plans are assumed. Based on this condition, this study proposes port entry procedure by using UKC forecast/control system. By this procedure, maximum draft of port entry ship will be enlarged.

After the Great East Japan Earthquake 2011, Tokyo Metropolitan Area has faced on serious energy crisis. The government urged industries and citizen to decrease 15% energy consumption during July to September. This report developed a multiple regression model which can calibrate the energy demand without the earthquake effect. We clarified that the demand is explained by temperature data very well. Then we compared the estimated demand and the actual demand until September 22^nd. The actual situation of “Electricity Saving” and the dispersion effect were confirmed.
