A bubble economy occurs when asset prices inflate rapidly due to speculative investments, creating a false sense of economic prosperity. This phenomenon often leads to unsustainable growth, where the value of assets like real estate and stocks rises far beyond their intrinsic worth, eventually leading to a sharp decline or 'burst' of the bubble. In the context of urban transformations in Japanese cinema, the bubble economy symbolizes a period of extreme economic optimism and consumerism in Japan during the late 1980s and early 1990s.
