Designers from the Japanese firm N-Ark have released renderings for their idea of a post-apocalyptic paradise. This ocean-based mini-metropolis, currently named Dogen City, would provide a "self-sufficient habitat" anywhere in the oceans for its tens of thousands of residents.

The designers claim they took inspiration both from the Biblical Noah's Ark, for which the company is named, and from Elon Musk's SpaceX and his long-term goal of turning Mars into a second home for humanity in the event of an apocalypse.
The design of Dogen City resembles a circular construction with greenery all over the "ring," which measures about four kilometers (2.49 miles) in circumference. The designers even claim that residents will be able to walk from one end of the city to the other within an hour. In addition, N-Ark claims the circular construction of the floating city is specially designed to protect Dogen City from severe weather.
Dogen City is designed in three parts. The first part is a habitable ring containing the main residential zones. The second part is an undersea data center, complete with other essential institutions like medical and research facilities. The third part is a flexible inner ring with structures that can move freely in the inner bay of the floating city.
N-Ark designers promise to create a fully functioning floating city with all kinds of buildings and amenities, even promising a sports stadium. Some of these structures would even be able to sail to new locations around the ring as needed and will be resilient to the supposed effects of climate change.
The designers want Dogen City to be built in a new maritime economic zone called the "New Ocean."
"New Ocean is a term intended for the ocean version of the private space business innovation 'New Space' started by SpaceX," said the company in a statement. "We will propose six elements (medical, food, housing, information and electrical services) to realize New Ocean, promote the entry of various companies and promote ocean development activities."
"Through this, we aim to create maritime innovation and seek to create this future together with participating companies, governments and universities," concluded the designers.
N-Ark's overarching goal for New Ocean is to create "a new economic ecosystem" made up of multiple naval cities and to transform the world's oceans into a globe-spanning "sphere of survival."
To realize its goal, N-Ark has set up several working groups that will study potential activities and policies in three key areas that can realize New Ocean – ocean business development, ocean technology development and ocean deregulation.
N-Ark's goal is to receive approval for the construction of Dogen City in a specific part of the ocean by 2027, and for the city itself to be completed by 2030.
