Around 81 percent of Japanese are opposed to the construction of the new Olympic stadium, whose costs have doubled with respect to the original budget, according to a survey by state broadcaster NHK published on Tuesday.

Only 13 percent of those surveyed approved of the project, according to the telephonic survey of some thousand people over the age of 20 years.

Criticism has intensified in recent weeks, after Japan Sport Council confirmed that its cost would escalate to $2.06 billion, nearly double the original budget.

On Friday, Japanese Education and Sports Minister Hakubun Shimomura called for an investigation and said the committee in charge was careless in selecting a design without taking into account the cost.

Japanese newspapers, including Asahi and Nikkei, have also criticized the high cost of the project in their editorials, while social networking sites are flooded with posts mocking the new stadium.
