à Âtemachi derives its name of à Âtemon ("Great Hand Gate") of Edo Castle. During the Edo period, various daimyà Âs constructed their lavish residences outside the castle, such as the residence of the daimyà  Matsudaira Tadamasa. à Âtemachi was completely destroyed during the Great Fire of Meireki in 1657. It was rebuilt, albeit on a smaller, less grand scale. à Âtemachi remained however in the possession of the various daimyà  families until the end of the Tokugawa system and the start of the Meiji period in the 1860s. The various daimyà  families lost their lots as the area was repossessed by the government, who constructed various governmental offices. Today nothing remains of its residential past, the area is dotted with modern high-rise buildings.
In order to gain revenue, the government decided to sell the area into private hands. The area was completely redeveloped.
