In the present investigation, an estimation of the growth of heat island development of Tokyo metropolis which accounts nearly 100 sq. km of areal spread has been carried out. Band 6 data of LANDSAT TM (Thematic Mapper) data acquired on August 1984 and 1994 have been used for estimating the expansion of the heat island development. Since the vegetation decrease is usually associated with the heat island development, a ratio of green covering has also been assessed using TM data. In order to establish the relationship with the air temperature, AMeDAS(Automated Meteorological Data Acquisition System) data have been correlated.

We proposed a method to compensate incomplete observations and made a study of environmental problem, water quality of Tama-River in Tokyo.The method is based on interpolations of the multi-layer neural networks. We call the approach as CQSAR method .which can compensate the defect data.The water quality data include defects which will give wrong effect to other normal data. The CQSAR method suppresses the wrong effect .Thus, we believe that the proposed CQSAR method has practical usability for environment examinations.

The purpose of this study is to consider the idea and the background of the establishment of master plans for parks and green spaces of metropolis in Japan, China and Korea after a careful comparative review of layout planning of green areas, plan objectives, future images and main measures. The method of study is the analysis of the control and plans in these three countries. The study reveals the characteristic of each plan as follows: 1) the conservation and revitalization of the shape of land and the river system in Tokyo; 2) the materialization of ideal green spaces in Beijing, the combination of the ring green and the radial layout of parks and green spaces; 3) the combination of cruciform greenery and the utilized existing public open spaces in Seoul. The result also shows that these cities have the different development of projects but face the common challenges.

The purpose of this study is to provide basic information and guide line for designing hotels located in metropolis by analyzing the spatial configuration of public area. As the sample of analysis, ten hotels are selected in Tokyo area, which were constructed during 1970 to 1990; the period was characterized by booming hotel constructions. The findings of the above analytical survey might be summarized as follows. First of all, it was found that all hotels constructed during the above mentioned periods could be classified into two categories according to their block type such as interlocking form and form within form types. It also observed the six hotels out of then had adopted form within form, beside, the left four hotels were constructed along the interlocking form type. Secondly, as regard to the functional space configuration of the public area, it was found that, in case of eight hotels, the upper part of the building which allocated as residential quarter are configured as linear type. As regard the lower part, however, it was found that different types are adopted. For instance, five hotels had adopted con-course types for the lower level that is spared for the public/service area. Beside, it was also found that, out of above five hotels, three hotels took form within type and the other two adopted compromising type. Thirdly, as regard to the composition of public area, it was found that, the quarters are allocated as follows, such as 34.11 percent for public, 28.99 percent for sales and 33.07 percent for service quarter.
