The area of Tokyo has been developed quickly through the radical change of urban disasters; Great Kanto earthquake and fire, American bombing, etc. But some areas were saved andsettled the strong identity of traditional Japanese town. Tokyo is metabolized itself from big plots with few land owners in the past then became smaller. Present situation, the city is dense the vertical community(high-rise building) on compliling land plots. Some are gentrified, but does the gentrifcation destroy the identity of the place just before the change?
