The aim of this study is to clarify the spatial composition of contemporary Japanese urban houses in terms of relations between interior rooms and exterior rooms. Exterior rooms are defined as exterior space limited by architectual compositional elements. First relations between fellow exterior rooms are analyzed in two levels of composition: arrangement and connection of fellow exterior rooms. Secondly relations between interior rooms and exterior rooms are analyzed in two levels of composition: arrangement and connection of interior rooms and exterior rooms. Then we found 13 types of comnosition. Comparing every type, characters of composilion are clarified From these considerations, we found that expression of composition, which network interior rooms and exterior rooms in three dimensions, formed in contemporary Japanese urban houses.

This study aims to validate the vacancy rate and number of vacant houses in the Housing and Land survey. Determining the actual vacancy rate and numbers of vacant houses contributes significantly to housing policy. No preceding research has been conducted with the same aim. The research method is as follows. 1. Confirm the vacancy survey method utilized by the Housing and Land survey. 2. Compare the results of the Ministry of Land, Infrastructure, Transport and Tourism vacancy survey and Housing and Land survey. 3. Compare the results of the house vacancy survey by municipality and Housing and Land survey. 4. Compare vacancy rates obtained using the number of census households and from the results of Housing and Land survey. 5. Compare the results of the vacancy rate using the SUUMO-ZENRIN data for Tokyo's 23 wards and Housing and Land survey. Based on these results, the validity of the vacancy rate and number of vacant houses in the residential land survey is examined. The results of the research are as follows. 1. The vacancy survey method of Housing and Land survey relies on a visual inspection overview. 2. The vacancy rate in the Ministry of Land, Infrastructure, Transportation and Tourism's vacancy survey (6.7-8.9%) is lower than that in Housing and Land survey (over 10%). The Ministry's vacancy survey stated that visual inspection is an inaccurate survey method. 3. The vacancy rate in the municipality's vacancy survey (1.6-7.4%) is lower than that in Housing and Land survey (10.3-14.6%). Most municipal vacancy surveys are conducted for all houses (Table 1). 4. The vacancy rate obtained using the census household number (2008: 10.0%) is lower than that in Housing and Land survey (2010: 13.9%) (Fig. 1). 5. The vacancy rate using the SUUMO-ZENRIN data (6.9%) is lower than that in Housing and Land survey (12.3%) (Fig. 2). - The SUUMO data cover 80% of the common housing residences in Tokyo's 23 wards (Table 2). - In Tokyo metropolitan area, the vacancy rate of housing with an area less than 25 square meters is high (12.2%) (Table 3). - In Tokyo metropolitan area, the vacancy rate of houses built after 1996 is high (10.1%) (Table 3). The conclusions are as follows. 1. The vacancy rate in Housing and Land survey is likely to be exaggerated. 2. The actual vacancy rate is likely to be 10% or less. 3. The actual number of vacant houses is likely to be 4-5 million. Future tasks are as follows: 1. To find an appropriate vacancy rate for each area. 2. To find a simple and accurate method of identifying vacant houses.

This paper intends to clarify block formation and house types of Wolvendaal, Colombo, Sri Lanka, and analyze their transformation process. The research on which this paper is based is the further study of the project called 'Field Research on Origin, Transformation, Conversion and Conservation of Urban Space of Colonial Cities', which the major targets are Dutch colonial cities all over the world. Further to this project, comparing colonial cities in South Asia, in terms of spatial formation and transformation is the ambitious objective of this research. Another purpose is to elucidate the Dutch way of houses construction in their colonial cities, where in Wolvendaal, Dutch developed the form of town houses for high-density living. Colombo was once a head quarter of Ceylon, one of five administrative districts laid by Dutch on South Asia. Wolfendaal also played an important role in British colonial period when the city experienced rapid growth. At present, there still holds numerous town houses. This paper clarifies the spatial organization of Wolvendaal, by analyzing the distribution pattern of its facilities and block formation, based on field surveys. At the last chapter, the paper focuses on house types of Wolvendaal identified according to their physical features and planning parameters, while the transformation process of these house types are discussed as well. This paper suggests that Dutch colonial town houses still playing an important role in the organization of special formation of Wolvendaal.

 The aim of this study is to clarify the composition of “townhouse type” architecture by articulation and integration of depth. Townhouse type is defined as the house on the site with frontage narrower than depth. At first, we define “vertical void” as the atrium and garden that is what to bring wind and light into the interior space. The compositional forms of townhouse type are defined through the combination of position of vertical void, handling of lighting surface and staircase in the vertical void. As a result, it is revealed that the articulation and integration of depth in compositional form of townhouse is generated by four stage of differentiation, which are established in containment relationship of concentric.

The aim of this study is to clarify the rhetoric of composition on open bedrooms in Japanese contemporary houses. Continuity of spaces including open bedrooms is more complex because of the necessity of privacy and time-sharing. Thus new relationships emerge from the conflict of spatial continuity within private space. In this study, the compositional characters of open bedrooms are analyzed in terms of certain components: articulation, transparency, circulation, and relation to architectural elements. As a result, compositional patterns are defined by the combination of these components of the open bedrooms. Finally, the rhetoric of composition is revealed from overlapping of programmatic distinction and spatial contrast in the continuity of the common and bedroom areas.

In this paper, the relationship between building typology and fragmental urban morphology viewed from building front of corner as a common condition covered over Shimo-kitazawa is clarified in order to find out the physical order of the district well known for its complexed and intimate atmosphere. In the first half part, the typology of the corner buildings is led by considering the relationship between building element and volume, and the way how the buildings respond to the corner is clarified. In the latter half part, the conbinations of the corner buildings' type are examined in each corner. As a result, it does not seems that the same type of corner buildings stand next each other, however, linguistic rules such as elements and volumes shared by corner buildings in the district work better to know the relationship between buildings and urbanmorphologies in contemporary fluid urban context.

The 2011 off the Pacific coast of Tohoku Earthquake (M 9.0) is the greatest earthquake in Japan. Analysis of GPS network, such as GEONET by Geospatial Information Authority of Japan, has revealed the crustal deformation distribution due to the earthquake. On the other hand, the crustal deformation distribution can be estimated from the displacement waveform calculated by integrating the accelogram observed by strong motion seismometer. This method would be used complementary with GPS analysis. In this study, we calculated the crustal deformation distribution due to the 2011 off the Pacific coast of Tohoku Earthquake from the accelograms recorded on strong motion observation network K-NET and KiK-net by National Research Institute for Earth Science and Disaster Prevention. The crustal deformation distribution calculated from strong motion records is consistent with that by GPS observation. In addition, the displacement waveforms estimated from strong motion records are in good agreement with that from 1 Hz GPS analysis.

A simple seismic isolation system by leveraging buoyancy has been devised for spread foundation structures. Through dynamic centrifuge tests, it is shown experimentally that a sliding isolation effect arises during seismic loading if a buoyant force of appropriate magnitude is applied to the base of the foundation. It is confirmed that seismic isolation performance tends to improve as the buoyancy-to-weight ratio increases. Performance when the buoyancy-to-weight ratio is 90% or more is particularly good, and the maximum response acceleration of a structure can be reduced to below 100 cm/s<sup>2</sup> against a sinusoidal wave with a maximum acceleration of 500 cm/s<sup>2</sup>.
