Tokyo's public parks are high-tech disaster hubs designed to transform into survival centers during major earthquakes.

Tokyo's disaster-prevention parks, such as Hikarigaoka Park and Rinkai Disaster Prevention Park, are engineered specifically to mitigate the impact of the 'Big One' earthquake. These sites are part of a massive urban planning initiative led by the Tokyo Metropolitan Government to create 'evacuation corridors' and 'survival islands.' The 'kamado' benches are built with heavy stone bases that can withstand high heat once the wooden slats are removed for fuel or storage.The emergency manhole toilets are strategically placed over deep sewer lines to ensure waste management remains functional even when the water supply is cut. These systems were tested and refined following the lessons learned from the 1995 Great Hanshin Earthquake and the 2011 Tohoku disaster. Many parks also house massive underground cisterns capable of holding thousands of liters of drinking water for stranded residents.In addition to life-support systems, these parks act as critical firebreaks to prevent the spread of urban fires across Tokyo's densely packed neighborhoods. Solar-powered charging stations and lighting systems are installed to provide communication and visibility during prolonged blackouts. The Rinkai Disaster Prevention Park even serves as a central headquarters for the government's emergency response teams, featuring a 13.2-hectare area dedicated to disaster management and training.
