US architect Kohn Pedersen Fox (KPF) and structural engineer Leslie E Robertson Associates (LERA) have proposed the creation of a new city in Tokyo Bay that will include a “cloud harvesting” mile-high residential tower and a Hyperloop transport system.
The city would be built on a series of reclaimed islands stretching across the 14km span of the bay. The aim is to help defend it against earthquakes, floods and typhoons, which are likely to be exacerbated by global warming.
The plan, called “Next Tokyo”, envisages using the islands as a physical buffer to protect Tokyo’s low lying shoreline, as well as providing homes for about half a million people.

To avoid pumping water to the upper storeys, the façade of the building would be designed to collect, treat, and store water from clouds and pipe it to apartments using gravity distribution.
And to tackle the question of vertical transport – the bête noire of supertall buildings – the tower would make use of ThyssenKrupp’s Multi cable-free elevators, which can run vertically and horizontally.
The city would have aquaponic enclosures for growing algae
The city would also include urban farms, including “fields” on the bay itself, which could be used to grow algae.
The futuristic scheme was put forward as a Council on Tall Buildings and Urban Habitat research paper last year.
The idea of building on Tokyo Bay is not a new one. At the time of the 1960 Tokyo Olympics, the Metabolist architect Kenzo Tange proposed the building of a “linear megastructure” across the bay – effectively a city on a bridge.
