<p> In Akihabara, where various specialty stores accumulate, people gather searching for limited and rare products and exchange them to share their hobbies and interests outside the store, forming a kind of public sphere.</p><p> This paper clarifies the mechanism of forming "the place for exchanges of goods".</p><p> To grasp this mechanism that are common in the outdoor space of Akihabara is also important in considering the value of downtown, which used to be discussed with words "bustle" and was not considered its social meaning.</p><p> </p><p> 1) Geographical characteristics of group staying behavior on the street</p><p> By patrolling Akihabara district, the distribution of places for exchanges of goods on the street was clarified from the wide-area viewpoint. Through this survey 12 locations were extracted where "appreciation and exchange" activities were concentrated, and from these locations it became clear that place for exchanges of goods tend to be formed in the near ground where manga, anime, and game content is sold.</p><p> </p><p> 2) Behavior and spatial transformation of places for exchanges of goods</p><p> From the fixed-point observation investigation, the change of the range in which space for exchanges of goods forms and the change of the behavior were analyzed. As a result, special characters of places where exchanges of goods are likely to happen were grasped from a microscopic viewpoint. It has become clear that place for exchanges of goods occurs avoiding the flow of people. It was also confirmed that the larger the number of members, the more they stayed in the environment surrounded by street objects.</p><p> </p><p> 3) Behavioral psychology of people who form places for exchanges of goods</p><p> Hearing investigation clarified what kind of behavioral psychology were seen behind forming the places for exchanges of goods, and what kind of actions were done for making their own place on the street. As a result, two types of actions were identified: "exchange of goods" and "exchange of information". It was confirmed that places for exchanges of goods occurs not only in search of a consensus of interests, but also in search of mutual empathy through the exchange of information in which people can deepen their knowledge of hobbies and preferences. It also became clear that they formed or joined in places for exchanges of goods with 9 kinds of behavioral psychology.</p>

<p> Encouraged by the "Work-Life Balance Charter" formulated in 2007, which recommended various ways of working and living, the promotion of side jobs in companies and the activities of people in their hobbies and leisure have become active.</p><p> As the work environment changes, people not only realize hobbies and side jobs, but also create encounters and relationships with others through rental spaces dealt on the website.</p><p> In this way, rental space, which has emerged in large numbers in urban areas and is being used for a variety of purposes, has the potential to become a place for new interaction.</p><p> In this paper, we conducted basic research on 1, 000 rental spaces in the Tokyo area (Tokyo, Kanagawa, Chiba, Saitama), and clarified the basic performance and regional characteristics of rental spaces.</p><p> In addition, by conducting interviews with owners of rental spaces where they engage in side-business or hobby activities, we were able to get close to the actual status of rental spaces management and usage, and clarified the social role of them.</p><p> These results are considered to be important and have implications for the utilization of urban building stock for diverse ways of working and self-realization.</p><p> </p><p> 1) Basic performance and regional characteristics of rental spaces</p><p> Existing uses of rental space are classified into four categories: residential, commercial, entertainment and rental only. The recommended uses on the website are classified into four categories: corporate, personal, interactive, and presentation.</p><p> Next, performance of RS as an existing building stock and performance of rental space for each recommended application were clarified. In addition, we were able to obtain 3 types of regional characteristics of rental space from the information of existing uses of them, and found 16 characteristic regions explained by them.</p><p> </p><p> 2) Reason for occurrence of rental spaces and devices for operation</p><p> As a result of interviews with rental space owner, we found that there were four reasons for the occurrence of rental spaces. Also, by starting rental spaces, we learned that these place has become a place to support and contribute, and a place where new encounters and relationships are created. Also, we found out that the owner carries out his own examination when renting a place.</p><p> </p><p> 3) Actual situation of use of rental spaces and values for users</p><p> As a result of analyzing the actual use of rental spaces obtained by interview survey to the owners, it was clarified that the users are seeking five values of place; "Space to be rented that meets the purpose needed in the short term", "Space for showing their hobby", "Space for challenge of new work transformed from their hobbies", "Space for realization of free self world view" and "Space for mental recovery".</p>

<p>本稿では地域コミュニティに開放された空間をもつサービス付き高齢者向け住宅の空間と運営に着目し、必ずしも富裕層向けでない、高齢者が享受できる豊かな生活を提供していることを示した。空間の面では、居住者と地域住民が共存できるように3つの秩序立ての工夫を行っており、他事例でも応用可能な知見だと考えられる。運営の面では、居住者集団に能動的な交流を支援する事業者の介入意向が居住者の能動的な行動を促す点で重要であることがわかった。一方、課題としては利用者のマナーの悪化や利用しにくい共用部配置になっているものがわかった。また、2つの調査により、共用空間の空間的特徴や多くの人が利用する場合の秩序立ての工夫、住宅の開発経緯、開放的な共用空間の利用実態などを明らかにした。</p>

<p> Edward Relph, a Canadian geographer said that there are psychological connections named "sense of place" between people and place, and they are important in terms of making good places. In Japan, It is said that the urban developments without consideration of psychological connections have destroyed places and their social memory. The purpose of this research is to analyze the character and inheritance of "sense of place", by observing habitual use of places inherited in university students in Takadanobaba. There were three investigations and followings were obtained:</p><p> </p><p>1) The whole picture of places where university students usually use</p><p> It became clear that the places where university students usually use can be divided into fifty four groups based on the industry classification. University facilities, Izakaya, Ramen shop etc. were the most popular places. And it became clear that the places where university students usually use can be roughly divided into nine groups through analysis of purpose for using place. There are the places for intellectual activities, cultural activities, sports, shopping, drinking parties, eating, gathering, killing time and rest. Moreover, it became clear that university students were relating nine places with each other to be network.</p><p> </p><p>2) The target youth's formation process of Local-oriented mind</p><p> 162 habitual uses of places are gained through the survey. They can be roughly classified into two actions. One is action done by using necessary items already prepared in the places, and the other is actions done by bringing necessary items from other places by themselves. The latter is done in the outdoor space, and it became clear that it is done outside of university more than inside of university. It is confirmed that most places where habitual use of places are done were located around each campus and Takadanobaba Station. And it became clear that many habitual uses of places are done in three types of places; places for leisure activity, places as node, and places for moving.</p><p> </p><p>3) Actors for inheritance of "sense of place"</p><p> 134 habitual uses of places are inherited beyond school grade. Groups or people keeping on planning events and the groups with multi-generation members are main actors for inheritance of the habitual use of places, thus they are considered to be one of the actors for inheritance of "sense of place". And it became clear that two environments were important for the inheritance of "sense of place"; appropriate urban space for purpose and the experience of seeing behavior of others.</p>

<p> In many developed countries including Japan, it has been pointed out that the conventional intermediate group that stabilized society has been dismantled, and isolated individuals are exposed. On the other hand, in recent years, the group of young people who tend to build a strong human relationship locally and to complete the living area there has been drawing attention as one of the typologies of behavior that characterize the youth near the city center. They have been discussed mainly in the field of marketing in terms of their consumption behavior. Moreover, it has been pointed out that this group of youth tends to participate in regional events actively, such as local festivals and to have an orientation for local settlement. It is thought that their orientation for local settlement is based on local-oriented mind, which is formed with friends of elementary and junior high school days.</p><p> The purpose of this paper is to clarify the process that the group of young people, as an intermediate group based on the experiences of elementary and junior high school days, forming local-oriented mind from group discussion and life story survey. There were three investigations and following was obtained:</p><p> </p><p> 1) The target youth's sense of belonging to local area</p><p> The local memories shared by the group were collected by group discussion under daily circumstances and classified into seven topics. Also, by analyzing the transition of conversation, it became clear that the topic related to the comparison with the city center is the important one linked with many topics. Based on the result, this paper analyzed how the target young people form a sense of belonging to the localities from the viewpoint of the distinction of behaviors in between city center and their local area. As a result, the target young people formed a sense of belonging to the localities by we-feeling; They do not pay attention to interpersonal attitudes, conversation contents, and clothes except for superior people in their local area. They try to be associate with someone carefully in the local are because they think the rumors spread very quickly. And unlike in the city, they can enjoy entertainment activities without considering trends.</p><p> </p><p> 2) The target youth's formation process of Local-oriented mind</p><p> Through interview of life story, it became obvious that the range of activities in junior high school days influences the formation of intermediate group by analyzing the local scope affecting the formation of intermediate group from the psychological local scope and places spoken as activity places by developmental stages of youth. Also, by analyzing the temporal and spatial changes of young activities that form local-oriented and its factors from contents of narratives, it became found that from the late infancy to the late adolescence, while receiving the influence of a friend relationship during junior high school, activities forming local-oriented mind is changing.</p><p> </p><p> 3) Consciousness for the living in the future and its background factors</p><p> From the results of the survey on the consciousness for the living in the future, it became clear that the intermediate group itself is mediating the local-oriented mind and influences the intention of settlement and the positive participation of local events.</p>

<p> The purpose of this study is to clarify the history of the development in Chiba Newtown and the process of the generation of non-dwelling facilities through the interviews on the developers and analysis of the physical change of living environment. Through the research, followings were identified:</p><p> </p><p> 1）The transition in Chiba NT development for 45 years</p><p> ChibaNT has been developed for 45 years, and the plan was changed several times. At first, the project aimed to supply housings and it registered as the "new housing and urban development project". Thus, residential area occupied a large proportion of area in masterplan. However, the plan and its concept changed and the development area were shrunk, and it had decisive influence on forming today's living environment. Especially, the number of commercial and business facility estates has increased based on the change of plan which introduces specific business facilities and multiple land use. And also the developers actively attracted private enterprises by introducing "Limited-term land rent right." In addition, the change was influenced from rapid change of housing demands and the attack of expropriation committee in Chiba by citizens who are protesting against Narita Airport construction.</p><p> </p><p> 2）Emergence process and accumulation of non-dwelling facilities</p><p> Huge part of the area for residential estate change to the area for the commercial and business facilities, under the influences of the change of the plan including the shrinking of the development area, extension of planning period, and introducing of the estate of specific business facilities and multiple land use. Especially, the ratio of commercial and business facility estates in Chuou district and Makinohara district became large, and a lot of non-dwelling facilities were built between 1995 and 2015. And this change overlaps with the change on the masterplan. In 1995, small commercial facilities located near ChibaNT-Chuou Sta. and at neighborhood centers and a business concentration area were being formed on the north side of ChibaNT-Chuou Sta. On the other hand, in 2015, large commercial facilities located near ChibaNT-Chuou Sta. and along the main road, and the new residential areas are constructing. Laboratories and offices accumulated in "business mall", and logistics facilities were being formed in the northeastern part of the Chuou district.</p><p> As described above, there are two types of accumulation trend in the commercial and business facility estate, which was changed from residential estate. One is the accumulation of large commercial facilities, another one is that of logistics and business facilities.</p>

&nbsp;Looking over the updating of urban space such as advanced use of space and function update is highly suggestive in reading social issues of each age and the consciousness of planners. Nowadays, with the relocation of the Olympic games and Tsukiji Market, interest in urban space renewal is increasing. It is not a regional fragmentary discussion, but it is required to summarize the whole picture of space updating and designer's awareness that has gone through in Tokyo and to critically discuss future updating methods.<br>&nbsp;In this paper, taking the 77 districts of urban redevelopment as an example, we examined what kinds of areas have been subject to renewal in Tokyo and how the new city image has been drawn for those areas in a timely manner. Through this investigation, the whole picture of the renewal of urban space that has been done so far was identified based on the statistical analysis.<br><br>&nbsp;1) The typology of existing environment and building change<br>&nbsp;We classified the former land use targeted by the Tokyo Metropolitan Government for redevelopment projects and analyzed the renewal of building use and building coverage by development on a timely basis for each type. As a first result, seven types of conventional land use were obtained, and it became clear that they are changing to biased use. Secondly, at the initial stage of redevelopment, the pension rate of business facilities has been on an upward trend, but in recent years a wider open space has been added. On the other hand, it was found that the building peculiarity is planned to increase in the redevelopment of the residential area in recent years.<br><br>&nbsp;2) The transition of aims of district plan by administration<br>&nbsp;We categorized the development goals that Tokyo Metropolitan Government gave to each district plan and analyzed their regional differences and transitions. As a result, four types of aim were obtained. While the "Cutting-edge development driving type" that forms a new city has decreased, it is clarified that "Habitability raising type" that improves the basic performance for living in the area tends to increase mainly in the three central wards of Tokyo.<br><br>&nbsp;3) Planner's discourses about concept of area update and interpretation of existing environments<br>&nbsp;By analyzing the narratives on architectural specialty magazines that argued about the plans in the areas targeted for redevelopment, we revealed the transition of discussions that occurred with redevelopment. In the early stage of redevelopment, despite the immature debate, there was a tendency to tell the consciousness for new age and forming of new urban images. In recent years the discussion has matured, and development has been discussed from various viewpoints. However, the trend of new age consciousness and urban images tends to be decreasing, and it became clear that the explanation of the problems rooted in the community and the necessity of urban renewal are becoming the main story for urban update, instead of creating the new vision of Tokyo.

&nbsp;In Tokyo, the accumulation of various restaurants is realized as resources of food culture. Nowadays, &ldquo;eating experiences&rdquo; in restaurants is getting important. However, the study on the quality of eating experiences and its geographical characters has hardly been conducted. Thus, it is important to reveal the empirical value of eating in the urban area. The purpose of this study is to identify the geographical characteristics of restaurants accumulation and &ldquo;eating experiences&rdquo; within Tokyo wards area. Through this research, the following has been identified:<br><br>&nbsp;1) The distribution characteristics of restaurants accumulation<br>&nbsp;In the 3^rd chapter, the correlations among the geographical distribution trend of 19 types of restaurants were revealed. They were divided into 3 similar groups and 7 independent groups. Then these accumulations were categorized into 3 similar groups. &ldquo;Types with correlation between diner (A. - E.)&rdquo; accumulated along Yamanote line and the linear area spreading from central Tokyo area to Shibuya area. &ldquo;F. Traditional food and Japanese Food&rdquo; accumulated into northern Tokyo wards area. &ldquo;G. Soba and Udon and Chinese Food&rdquo; accumulated into eastern Tokyo wards area.<br>&nbsp;Second, the accumulation characteristic of all restaurants was figured out and it became clear that restaurants accumulated in 5 areas; (a) area with some parallel lines in Tokyo wards area, (b) lines from Shinjuku to eastern wards area, (c) lines from Shibuya to eastern wards area, (d) around Ikebukuro, and (e) some station areas on the suburban railroads. Third, based on these characteristics of restaurants accumulation and the number of passengers, station areas could be divided into 4 similar groups; (a) Multiple types, Few passengers, (b) Multiple types, Many passengers, (c) Single type, Few passengers, and (d) Single type, Many passengers.<br><br>&nbsp;2) The typology of eating experiences and its differences among station areas<br>&nbsp;In the 4^th chapter, station areas with noticeable trend of each groups based on the characteristics of restaurants accumulation and the number of passengers were extracted. These were 9 station areas, which are Keiseiueno, Uenookachimachi, Shinjuku, Shibuya, Higashishinjuku, Daikanyama, Kitasenju, Ohtemachi, and Meguro. Second, regional characteristics based on &ldquo;eating experience&rdquo; were cleared. As a result, 82 types of enjoyable &ldquo;eating experience&rdquo; in Tokyo wards area were extracted. Then, they are divided into &ldquo;contents (32)&rdquo;, &ldquo;spaces (26)&rdquo;, &ldquo;events (15)&rdquo; and &ldquo;surroundings (9)&rdquo;. With respect to &ldquo;contents&rdquo;, Higashishinjuku and Daikanyama shows original trend but others didn't have distinguished trend. With respect to &ldquo;spaces&rdquo;, there were no differences by station areas. With respect to &ldquo;events&rdquo;, there were no differences by station areas without Higashishinjuku and Ohtemachi. With respect to &ldquo;surroundings&rdquo;, it was identified that the &ldquo;surroundings&rdquo; is the most unique &ldquo;earing experiences&rdquo; which differs by station areas. Then, summarizing characteristics of station areas based on these 4 &ldquo;eating experiences&rdquo;, 5 regional characteristics based on specialized cluster within &ldquo;contents&rdquo; and extra specialization in eating experiences were identified; (a) enjoy contents (Uenookachimachi and Higashishinjuku), (b) enjoy alcoholic drink and spaces, (c) enjoy ambience, (d) enjoy events, and (e) enjoy location and night view. These characteristics were different from those we have seen in the analysis of restaurants accumulation and the number of passengers. Therefore these were unique characteristics seen from &ldquo;eating experiences&rdquo;.

&nbsp;As demands of consumers are getting more diverse, downtown and residential areas in Japan have changed to satisfy various image requirements, not just functional differences. It should not be overlooked that the activities of people who make, sell, and interact with their hobbies are growing to a non-negligible economic scale, with invisible change of landscape. In this research, through interview surveys at multiple exhibition spot sale meetings held in the Tokyo metropolitan area, we grasp the actual state of the hand-made craft market and the social background of their formation. We grasped the position of handmade craft market in chapter 2 and clarified the following three points.<br><br>&nbsp;1) The system of the places for activities constituting the hand-made craft market of hobbies<br>&nbsp;The places for procurement of materials diversified in the real space and the Internet space, and they came to satisfy the quality, kindness, reasonable prices, convenience for the producers. Production of handmade crafts are enhanced by outside places and services such as shared workshops and the vendor services. In addition, the places for selling works has also diversified, with exhibitions and craft market services, the producers felt delighted that their work gained empathy with the purchasers and exchanges between artists and fans were born. These facts lead to their motivation for making. Almost all of the producers are using SNS to receive information and stimulated from works of other artists, and they also try to exhibit / advertise their works in SNS. It was found that the development of SNS supported the hand-made craft market, which have physical and non-physical places on the internet, crossing the process of materials procurement, production of handcrafts, and selling of their works.<br><br>&nbsp;2) Types of hobby handmade craft market participants and their characters<br>&nbsp;Participants who started making their works and joined the handmade craft market could be classified into six types, and characters of each types are revealed, based on their motivations, sex, using of interest, working environment, school, occupation and so on. There are diverse participants, one purely enjoys making their works, while another one tries to sell their works, and some have activities for exhibitions and exchanges. It was found that these diverse participants with different purposes were gathered and formed a hand-made craft market.<br><br>&nbsp;3) Space and social function of the places for making handcrafts, case study of shared studios<br>&nbsp;In the chapter 5, we targeted at the &ldquo;share studio&rdquo;, which is a new working model for handmade crafts. The share studio is a space that can be flexibly changed in layout according to the purpose of use, such as the installation of wheeled equipment, and it has the features that they are located in convenient places close to the station. We had investigation at three shared studios in Tokyo. They are not only providing a place for production but also a system of support for manufacturing of both hobbies and main businesses, while they are also providing a place for exchange of artists and information. They also have a role of expanding the base of monozukuri. They are widely used as a place of production for people who are hard to make their works in their own houses. These shared studios are established as a place to support "making things by yourself that is not by mass production".

&nbsp;Since the Japanese housing system was marketed at the end of the 20th century, a huge amount of private sale housings were built and became a receiver for the people who returned to the metropolitan area. As more than 20 years have passed since the arrival of the era of urban core revival, it is indispensable to analyze &ldquo;lifestyle images&rdquo; seen in the housing market to read changes in the living environment.<br>&nbsp;The purpose of this paper is to clarify how residential housing has changed the living environment by analyzing expressions used in housing advertisement. There were three investigations and following was obtained:<br><br>&nbsp;1) Location and value change of private sale housing under the era of urban core revival<br>&nbsp;It became clear that the private sale housing in the era of urban core revival can be roughly divided into two groups. One is a group of houses (named &ldquo;standard private sale houses&rdquo;) with a price of 30-60 million yen in size of 60-89 square meters and a floor height of 15 floors or less, and the other is a group of houses with various characters (named &ldquo;special private sale houses&rdquo;). The former is distributed throughout the metropolitan area, whereas the latter was found to have a radial distribution structure centered around the Yamanote line. Also, paying attention to the difference in living environment value, the former will only enjoy the basic value, while the latter will enjoy more diverse and image-wise value. As mentioned above, two groups with different properties have been supplied to private sale houses to promote population return to central Tokyo.<br><br>&nbsp;2) Transition of the regional image caused by soaring and falling of residential land prices<br>&nbsp;Based on the value expression of the location area in the housing advertisement, it became clear that the regional images were categorized into six clusters, each having a unique distribution tendency. While three regional images of &ldquo;CL1: low convenience area with lacking of living facilities&rdquo;, &ldquo;CL3: low image area with lacking of natural values&rdquo;, and &ldquo;CL4: high ground permanent-living area&rdquo; tend to be distributed throughout the metropolitan area, &rdquo;CL2 education / security specialized area&rdquo; tend to be distributed around 20km from central Tokyo, and &ldquo;CL5: urban area with entertainment&rdquo; and &ldquo;CL6: advanced image inclusive area&rdquo; are distributed mainly around the peripheral area and some coastal areas. Next, looking at the transition of regional images under the return to the city center, we found that the transition to &ldquo;CL3: low image area with lacking of natural values&rdquo; is mainly progressing in the whole metropolitan area. Areas that achieved transitions of regional images different from these were extracted as "transitions of unique area images" from this analysis.<br><br>&nbsp;3) Actual state of the areas that achieved transitions of unique regional images<br>&nbsp;In the six areas that achieved "transitions of unique area images", small factories, condominiums, detached houses, apartment complexes, corporate houses were found to be subject to renewal. Among them, in the price rising region, there is a diverse characteristic in the change of building uses, and accordingly there was a difference in the transition of the regional images. On the other hand, in the price falling area, construction of condominiums is progressing but there is no clear difference in the change of building use. Instead of it, it was grasped that cognitive changes in location areas such as expansion of the view of the surrounding area, replacement from the natural environment to the child rearing environment, accreditation and boost by the administration are strongly influenced on the transition of regional images in the price falling area.

東京「下町」は、近年東京スカイツリーの開業を契機に観光地化し、多くの観光客を誘致している。加えて、現在下町は、人的・物的双方の観点から、これまでにない都市更新の時期を迎えている。これらの要因から歴史の中で育まれてきた下町像をいかに受け継いでいくかという問題が生じており、今後さらに観光地化していくであろう東京スカイツリー周辺地域でこれまで脈々と共有されてきた下町像を、それが伝承されてきた人間関係のあり方とともに記録し、地域の共有財として継承する必要性を再認識することは、地域の将来像の構築を考える上で重要である。本研究では、東京スカイツリーの建設により近年下町観光地として注目される墨田区の東京スカイツリー周辺地域を対象として、具体的には以下の２点を明らかにする。 1)伝承集団の分類と伝承行動の実態（3章） 2)地域の記憶にみる下町像の世代間差異および語られる下町像と伝承集団の関係(4章)以上より、生活者のもつ地域の記憶と伝承行為からTS開発以前より共有される下町像を捉えた。

&nbsp;Since people's needs for living environment are currently getting more diverse and qualitative, traditional model which links life-stages directly to housings like &ldquo;jutaku-sugoroku (board game of housings)&rdquo; in modern ages, will not enough effective to grasp the actual situation of people's housing preference action.<br>&nbsp;Instead of evaluating grade of the living environment by a unitary index, the method to reevaluate the living environment by plural subjective values is needed.<br><br>&nbsp;Based on such idea, the author had found over 100 values of lifestyle, which were supplied to housing market, by analyzing the housing advertisements from 1980 to 2010. To compare with these results, this paper on the contrary aims to clarify the desires for living environment that people have when they choose their own housings.<br>&nbsp;In this research questionnaires were distributed for 5,749 residents around Tokyo metropolitan area, to investigate how strongly they want each values when they were selecting their house, and were they satisfied enough or not.<br><br>&nbsp;In chapter 3, by analyzing the answers of questionnaires, desires for living environment were classified into 5 groups: 1) desires for urban images, 2) desires for luxury images, 3) desires for accessibilities, 4) desires for everyday life, and 5) desires for nature images. These desires have a qualitative variation from &ldquo;basic desires&rdquo; to &ldquo;selective&rdquo; ones.<br>&nbsp;Based on these desires and social characters, the subjects that select living environment were also classified into 5 groups: 1) a group with low income and basic desires, 2) a group with middle ages from suburbs who concentrates on everyday life desires, 3) a group with middle ages from suburbs who had desires around everyday life, 4) a group with middle and old ages from cities who had balanced desires, 5) a group with old ages and pursues all types of desires.<br><br>&nbsp;In chapter 4, process of housing preference was analyzed by evaluating compromise and satisfaction of desires. As a result, 5) a group with old ages and pursues all types of desires tends to have a choice that satisfies their first desires, while 4) a group with middle and old ages from cities who had balanced desires tends to have a choice with total change of their first desires. The subject groups 1), 2), 3) tend to have a choice with partial change in desires.<br>&nbsp;In short, a subject group that strongly intends desires tends to have lower satisfaction and compromise after deciding their house to buy.<br>&nbsp;At the same time, it was grasped that, as a result, the choice with the change of first desires will lead to the choice of a variety of housing types. Thus, the housing preference with less change of the first desires will let them enjoy "values as they demanded". In contrast to these cases, the housing preference with more change of desires will be accommodated by diverse housing types, with a satisfaction of desires that they did not have at first, namely "values they found".

&nbsp;The purpose of this research is to identify the spatiotemporal characteristics of values of living environment, based on the analysis of housing advertisements within the Tokyo metropolitan area from 1980 to 2010. (1)Firstly the values were sampled as 102 groups based on their meanings, and their tendency of increase and decrease was revealed. (2) Secondly the housings were classified into 7 types and their geographical characteristics were identified. (3)And finally the qualitative changes of the values which reflect the transformation of the center of tokyo metropolitan area were revealed, which were represented as &ldquo;being high-rised&rdquo; of housings, &ldquo;being imageable&rdquo; of the nature, &ldquo;being security - biased&rdquo; of safeties, and &rdquo;being individual - biased&rdquo; of families. At the same time in the whole metropolitan area, &ldquo;being indoor&ldquo; of the comfortableness and diversification of families were also identified.
