This study examined the effects of urban districts of harbor areas for controlling land use in urban areas that rank behind the Tokyo Metropolitan area, including the Osaka Bay coastal area with its concentration of population, size, and functions. As a result of the period of high economic growth, the Osaka Bay coastal area and other urban coastal areas in Japan have been developed with large-scale factories, harbor facilities, and open spaces in the coastal zones and with a high concentration urban functions in the inland zones. However, changes in the industrial structure have lead to the gradual transition of urban functions to these coastal zones. In spite of these changes, the coastal zones and inland zones exhibit significant differences in their urban structure, have various legal regulations so that they have become distinctly different land spaces, and are not being used effectively.

　

To promote the same usage in the coastal zones as the inland zones while maintaining a sense of closeness to the marine environment that utilizes the site characteristics, this study examined the effects of harbor legislation for urban districts of harbor areas, which serve as the guidelines for planning. The results show that the coastal areas and inland areas remain separated and that the effects of land usage controls and urban districts of harbor areas have not been fully utilized. We suggest the building of a social environment where private citizens can participate in planning and self-reliant change is encouraged together with the adoption of zoning allocations that join the coastal and inland areas.

The urban land use of urban coastal areas in Japan is advancing with shifts in regional structures, diversification of urban amenities, and other changes. However, since the original land use development purposes in the inland and coastal areas are different, the coastal areas are not always successful in effectively using the land. In previous papers, the authors have indicated that there are differences in coastal and inland areas due to differences in land use allocation patterns in these areas. This study is a continuation of these previous studies and attempts to gain an understanding of land use allocation patterns in urban coastal areas from the standpoints of aggregation of land use and land use clusters. The purpose of this study is to understand the current state of land use clusters and changes over time in urban coastal areas and to understand the appearance of land use clusters in the flow from the coastlines to inland areas.

　

The results of this study indicated that (1) overall, land use clusters were large in coastal areas and inland areas that were large in coastal areas and inland areas that were 10 km or more from the coast; (2) overall, land use clusters tended to be small-scaled and diversified; (3) cluster separation was observed in areas with large land use clusters, namely, coastal areas and inland areas that were 10 km from the coast; and (4) industrial site clusters, open space clusters, and public site clusters were large in the coastal areas and small in the inland areas. On the other hand, clusters for commercial sites, agricultural sites, and residential sites were small in the coastal areas and large in the inland areas.

Coastal area is one of the most attractive places not only for recreation but also educational purposes. Recently, it is reported from Psychologist that coastal wave sounds make us relax. The reason why makes us relax has not been clarified yet, however, recently also it is reported that inaudible sound which contains these sound, so call ultra-sonic property of frequency, makes human brain waves vital. The most of related past research has been made based on the audible sound. Since now, author has been conducted several experiments using ultra-sonic wave which was recorded from actual wave sound at the coast and examined its effectiveness.

　

In this paper, method of experiment and obtained result will be introduced and finally from the viewpoint of coastal marine tourism, sound resource management, as a new resource in the coastal area, will be discussed.

Recently activities around coastal areas have extended to ocean development and various life styles of humanity. People playing on seaside have been exposed to a lot of ultraviolet radiation. The effect of ultraviolet radiation in coastal zones is higher than that in terrestrial zones due to the reflection from the sea surface and sand. And ultraviolet radiation induces human erythema, melanization and photokerato - conjunctiva which harm cornea or conjunctiva. It is very important to prevent human body from the ultraviolet radiation. Conventionally, many sunshades are used to against to ultraviolet radiation on the beach. However, there is very little research to the sunshade design of the beach. Therefore, when designing the sunshade of the beach, the design has been carried out experientially. In this research, authors collected and analyzed the data about the sunshade of seashore resort hotels. After the data analysis, it was clear that:

　

　

From these data, the sunshade design on the beach can become easily.
