The city will even have its own launch pad for launching and receiving cargo and passenger rockets. It is not yet clear whether the city will be able to withstand the tsunami.

The project envisions a floating city with a radius of 1.58 kilometers and an outer perimeter of 4 kilometers. It is designed to provide permanent accommodation and employment for approximately 10,000 people and to host up to 30,000 tourists. Its round shape can withstand the strong waves of the surrounding sea.

The project will be divided into three separate areas:

• A populated ring containing the main residential area.
• An underwater data center that will be naturally cooled by the sea and will include city administration centers and medical research centers.
• Architecture floating inside an artificial bay formed by a ring-shaped structure.

A large number of green areas, nurseries to grow crops, schools, sports fields, hospitals, parks, stadiums, hotels and offices are envisaged. It is also possible to place a rocket launch and landing area just outside the city in N-Ark.

N-Ark estimates that the island city will consume only about 2 million liters of drinking water per year, which is rather modest. At the same time, it will generate 3,288 tons of waste per year, which will either have to be transported somewhere or somehow disposed of – this issue has not yet been resolved in detail.

Its own capacity will almost allow production at Dogen 7,000 tons of food and 22.2 gigawatts of electricity. Power generation will be extensive – solar panels on all roofs, windmills and turbines using underwater currents.

Construction cost is unknown. If the project is of interest to potential investors, a floating city could become a reality as early as 2030.
