Due to its location Tokyo is one of the most earthquake-prone cities in the world. At the same time the Greater Tokyo Area is the most populous metropolitan area in the world and is still growing, which makes the consequences of a possible earthquake even more threatening. Therefore the project is an earthquake-proven skyscraper in Akasaka,Tokyo. Additionally the project aims at two of the biggest japanese social problems in the foreseeable future. On the one hand the growing problem of social isolation in big cities like Tokyo. On the other hand the dramatic problems caused by an ageing society, as well as its questions of caring for the elderly and their integration into society and family. To solve these problems, the skyscraper implements two relatively new japanese concepts of living. First the concept of the 'Share House'. Planned for 16 to 48 persons it offers each person a separate apartement, as well as a community room at relatively cheap prices.The community room mostly consists of a big shared kitchen, a large living room and a small theme based room. Second the nursing-concept of 'Kinkyo'. With very few nursing homes available, most elderly rely on the care of their families. The permanent contact between each other often causes mental problems. Therefore the concept of 'Kinkyo' was created. The families still care for their elderly, but live nearby to get more privacy. Thus the skyscraper mostly consists of the two share house areas for elderly or regular people, with a mixture of singles, pairs and small families. Whilst separated by their floors, the inhabitants can still meet each other in the community floors and their community rooms. To complement the ideas of the 'Share House' and 'Kinkyo', the skyscraper also contains a kindergarten, a health center, two 'Shared Offices', as well as a traditional japanese onsen. The goal is to achieve the feeling of a 'vertical village' and to strengthen the cooperation between each other, as well as creating a new form of living. In addition to the functional aspects there is also a strong focus on earthquake protection. Already included in the preliminary design process, the static and structural dynamic concept only needs passive tools to achieve sufficient earthquake protection withinTokyo. Due to its sufficient earthquake protection, as well as its generous space the skyscraper can be transformed to a very good crisis management center during and after a natural disaster. Based on prepared emergency plans, the skyscraper becomes first point of contact and provides initial medical aid, emergency accomodations, but also longterm accomodations. To achieve these accomodations for up to 1550 persons, each one of the apartements as well as parts of the community rooms and the public spaces can be transformed.
