In recent years, Japanese automobile makers have been active in carrying out studies for tackling pollution in the environment. A reduction in the volume of traffic is now an indispensable topic of traffic conditions. Therefore, studies were made regarding a review of the history of an upgrade from streetcars to LRT (Light Rail Transit), the present situation of the prosperous introduction of LRT systems into various Western cities during recent years, and in addition, research concerning improvements and action for the maintenance of streetcars and LRT. As a result, it can be understood that the history of the abolition of the streetcar in the West resembles the same trend in Japan. However, due to a revival in the West, the position of the streetcar/LRT has recently become a part of urban transport system. Also, vitalization of the transport system to provide improved relations with automobiles, upgraded convenience, and activation in central city areas is being carried out. Although, a review of streetcar/LRT is gradually being performed in Japan, the law system and aspects of business in Japan are not equal to those in the West. Therefore, it can be said that an important subject is the substantiality of the law system in Japan and the pursuit of its improvement.
