2. Calculation of the percentage of ships calling
successively at multiple ports
This analysis used Lloyd’s data for port calls aroundthe world throughout the year to calculate thepercentage of ships which called successively at
multiple ports from among all ships visiting the bays
studied. Figure 1 shows changes of the percentage ofships calling successively at multiple ports from 2003to 2009. The objects of the analysis were Osaka Bay
and Tokyo Bay, where the cooperation policy had
been implemented, and for comparison purposes, Ise
Bay and Northern Kyushu. Three of the bays with theexemption of Ise Bay had tended to grow to 2006.
Between 2006 and 2008, there was no increase inTokyo Bay and Northern Kyushu, but Osaka Bay,
where the cooperation policy between ports had been
adopted, increased, and passing Tokyo Bay in 2008 to
take first place. To clarify the effectiveness of cooperation betweenports in greater detail for Osaka Bay and Tokyo Bay,the percentages of ships calling successively atmultiple ports before and after the policy wasintroduced, are shown in Table 1 by type of route. The
three route categories were all routes, routes in East
Asia (EA), and near-sea routes (calling only at ports inJapan, Korea, and Northern China (from Zhejiang
1. Introduction
In December 2007, the ports of Osaka Bay, which
had been divided into three ports, were integrated as
the Hanshin Port, and for foreign trading ships thatcall at two or more of these ports, the tonnage duescharged for each port call were reduced to an amountfor one port call. And prior to the unification of theports, a policy of halving the port dues for container
ships calling successively at 2 or more ports in the bay
was introduced in April of the same year. And in April
2009, Keihin Port also reduced the port dues forcontainer ships calling successively at 2 or more ports
within the bay to the dues for one port call.
This research calculated and analyzed thepercentage of ships calling successively at multiple
ports in a single bay in order to clarify theeffectiveness of the cooperation policy between ports.

Province north)). In Osaka Bay, only ships on thenear-sea routes increased after the reduction of port
dues, but after the unification, ships on all routes
increased, then in 2009, the percentages on all routes
began to decline. It is assumed that this was caused by
the world economic slump in the last half of 2008, butin Tokyo Bay, the percentage of ships calling
successively at multiple ports was maintained after thereduction of port dues.
3. Closing RemarkIn the future, we want to continue the analysis tocalculate the results of the reduction of port costs by
the cooperation policy between ports.
