I mean, what's changed in the interim to justify such overlay? Or was the original budget just daftly low?http://www.insidethegames.biz/articles/1042130/tokyo-government-review-predicts-olympic-and-paralympic-costs-could-reach-30-billion
A review commissioned by the Tokyo Government has predicted that total costs for the 2020 Olympic and Paralympic Games could exceed 3 trillion yen (£22 billion/$30 billion/€26 billion) unless drastic changes are made.
The latest figures are more than four times initial budget estimations.
Costs incurred constructing and maintaining both new and temporary stadiums are thought to have also contributed significantly along with transportation and security increases.
It was also claimed that the existing rowing and canoe sprint venue at the Sea Forest International Regatta Course on Tokyo Bay has risen to seven times its initial budget.
