Abstract
According to the formation of Keiyo coastal industrial area, newcomers have remarkably increased where natives have long been. In such area we searched environmental problems by analyzing the investigation of habitants consciousness. As a result, the following were discovered. (1) Among newcomers who live in companies houses or small rented houses have great disadvantage. Those who have been left from the 'policy of owing house' hold strong complaints about houses, which result in weakening their wish to domiciliate. (2) Both newcomers and natives are greatly discontented with environmental problems such as atomospheric pollution or danger of accidents caused by the industrial factories, and with the delay in constructing city facilities. These obstruct their wish to domiciliate, too. (3) People in companies' houses have strong dependence on their companies about residential and environmental problems. On the other hand, newcomers in rented houses are not easily accepted in the community system of natives. Each has obstruction in forming democratic community;newcomers and natives rarely have friendly relations with each other. (4) Under these circumstances, especially young generation of teen-agers, both of newcomers and natives, have much less difference in life consciousness mutually. There is possibility for both habitants to have more contact in future.
