Facilities that are shown on the Tokyo Disaster Prevention Map (examples)
- Shelters (避難所)

Places to which people can evacuate when it is dangerous or impossible for them to stay in their homes due to a disaster, such as schools and community centers. - Evacuation shelters (避難場所)

Places to which people can escape from danger, such as large parks, squares, and universities. - Temporary accommodation facilities (一時滞在施設)
Places where people who are outside (for example while shopping) at the time of the disaster and cannot return home can stay for up to three days. These include facilities run by the Tokyo Metropolitan Government. - Water supply bases (給水拠点)

Places where water is provided to people when the water supply is off due to a disaster. - Medical institutions (医療機関)

Hospitals etc. - Support stations for people attempting to return home during a disaster/Disaster support stations
(災害時帰宅支援ステーション、災害時サポートステーション)
