DIB-200 is a possible mixed use supertall skyscraper project proposed by Kajima Construction for Tokyo, Japan, designed by Sadaaki Masuda and Scott Howe.
However, Sadaaki Masuda claims that they could do little to influence the overall appearance of DIB-200 once the module had been designed and the parameters agreed upon.
Scott Howe sees their contribution as helping to make the building a pleasant place for a population equivalent to that of a medium-sized town.
Though Kajima is sticking with proven technology, it is taking conventional lift design to the limit with cables as long as 600 metres to provide the building's most direct service.
Between tiers, horizontal sky lobbies will link the towers, and contain shops, sports and cultural centres.
