A study is underway for the possible construction of a cable car linking 2020 Tokyo Olympic venues with a business area near the Ginza shopping district, a municipal government official has said.

A construction company is studying the feasibility of building a gondola lift to connect Shiodome on the western edge of Tokyo Bay to Toyosu on the east, said Takaaki Yamazaki, mayor of Koto Ward. The construction cost is estimated at ¥21.5 billion ($210 million), he said.

Koto Ward, where half the newly constructed competition sites will be located, is seeking to cash in on Japan's growing number of overseas visitors, which rose for two straight years to reach 10.4 million in 2013. The Olympics are estimated to lure 10.1 million visitors and staff to Tokyo over a 19-day period, according to a bid document.
