Japans national stadium, Tokyo, Japan

'Japans national stadium, Tokyo, Japan'

The stadium is scheduled for completion in 2018, and will play host to the 2019 Rugby World Cup, as well as forming the centrepiece of the 2020 Summer Olympics should Tokyo's bid prove successful.

Despite Japan's staggering national debt, the stadium is set to become the world's most expensive venue at current exchange rates. Assuming a construction budget of 130bn yen ($1.62bn/£1.02bn) is fully utilised, it will surpass the $1.6bn paid for the New Meadowlands Stadium, home of both the New York Giants and New York Jets.
