Company officials said Monday that Mori, chairman of Mori Building, died Thursday of heart failure. He was 77.
With visions of a "vertical garden city," Mori transformed Tokyo's landscape with mammoth mixed-use development projects, such as Roppongi Hills, Ark Hills and Atago Green Hills. Many buildings around the city bear his family name.
Other Asian cities also appealed to him.
His 101-story Shanghai World Financial Center, which opened in 2008, has the world's highest rooftop at 1,614 feet (492 meters) and highest observation deck. He acquired the site in 1994 and piling work began three years later just as the Asian financial crisis hit. The land sat idle for six years.
The project finally hit the market just as the Chinese property market began cooling after years of growth, although space remains tight for top-grade office space, the quality that Mori wanted to offer.
The company said Mori had been receiving medical treatment for some time but gave no further details.
Mori, from Japan's ancient capital of Kyoto, co-founded Mori Building with his father Taikichiro in 1959 and became president in 1993, when Japan's land prices were surging amid its "bubble" economy

Mr. Mori was an incredible man. He made Roppongi Hills, which is one of the biggest shopping centers in Tokyo, it even has a hotel and any kind of help or place you'd need. Only Tokyo Midtown came close! Sad...
