Opening the new runway in 2010 allows Tokyo International Airport to have 90,000 takeoffs and landings of international flights in a year. Narita International Airport, at the same time, plans to increase the number from 220,000 to 300,000 by 2014 in stages. This situation provides the surplus of departure and arrival slots at Narita, which is not only capable of expanding the frequency of international flights but also sufficiently assigned to the domestic flights. This research analyzes the improvement of passengers' convenience as well as the influence on the user benefit brought by the amplification of international flights at Narita.

This paper empirically analyzes the effect of merger between Delta and Northwest airlines on airfares. Simultaneous demand and pseudo-supply equations are estimated by using 2006-2009 the US airline industry data (18,779 samples) to derive this effect. The result shows that in some routes where there is either Delta or Northwest airlines, the merger leads to low airfares. This result may have been caused by pricing-reducing pressures from LCCs.

In the progress of supply chain management, traditional management of ports as an interface between shipping and land transport has faced serious limitations. This study analyzes these limitations and proposes a new direction towards ports as logistics center rather than maritime terminals, discussing new requirements for strategies and institutional capability of port authorities. With analyses of European ports recently corporatized, the effectiveness of port corporatization is evaluated in terms of such basic aspects as decision-making, financial autonomy, and ability to undertake a range of strategies, identifying key issues in corporatizing ports. Also considered are its implications to Japan's port policy.

The decreasing travel time reliability of urban railway services in the Tokyo Metropolitan Area is the result of the train delays in daily morning hour period. The proposed multi agent simulation model is developed to analyze train knock-on delay in a 48.3 km track length from Ngatsuda station of the Denentoshi line to Oshiage station of the Hanzomon line. The simulation part consists of a train traffic simulator and a passenger flow simulator with that works in parallel. The errors in the delay estimation of individual trains by the proposed simulator are within the allowable limits in comparison to the actual train delay. Some forecasting results of investment strategies designed to reduce delay can be assessed.

The purpose of this paper is to estimate the attraction indexes to identify the positions of Asian Countries and Regions in international tourism. Firstly, the probabilities of destination choice are calculated by the Origin-Destination matrices by the data of World Tourism Organization of United Nations from 1995 to 2008. Secondly, attraction indexes of each countries and regions are estimated by inverse problem of minimum of Sum of Squared Error between actual values and estimations by Huff model. It is possible to identify the trends of attraction indexes and to make a relative comparison by this analysis. It is also able to find the position of each countries and regions by positioning map for the identification of competition in Asian international tourism.
