一、前言近代的城市计划,哪怕是一小部分,也要等灾害发生之后才能实现。这样说并不过分。现在所见到的东京都中心的公路等城市基础设施,大部分都是在1923年关东大震灾的重建时期建成的。据说,当时声名显赫的丸之内在关东大震灾时也只是刚刚建成丸大厦,其余的土地仍是杂草丛生的荒野,而且,当时的城市中心——日本桥和京桥都烧毁殆尽,所以,新型都市才得以迅速地显露头角形成今天的繁荣景象。为了解决堆积如山的城市问题,彻底改造城市,现在似乎有一种渴望灾害马上就发生之感。可是,如果现在发生了大地震,是否真的 First, the preface Modern urban planning, even if it is a small part, but also to wait for the disaster to happen. This is not excessive. Most of the urban infrastructure such as roads and roads now seen in the center of Tokyo is built during the reconstruction of the Great Kanto Earthquake in 1923.

At that time, the city centers of Japan and Kyobashi were burnt down. New cities were quickly able to emerge to form today’s prosperity. In order to solve the problem of mountainous cities and transform the city completely, there seems to be a sense of urgency now that disasters happen. However, if there is a big earthquake now, is it true?
