The story so far
The national stadium maintenance plan was conducted mainly by the JSC = Japan Sports Promotion Center, and works originally designed by Iraqi female architects were adopted.

In the most frequent period, about 2,800 people worked per day, and the maintenance has been promoted.

However, according to the officials, there are many problems such as that it is expected that it will cost at least billions of yen to renovate it exclusively for ball games, and if the stage is placed in the field to open a concert, the turf will be greatly damaged It has been understood.
In response to this, the policy of making the stadium dedicated to ball games has been substantially changed, leaving the track for track.
Although had become policy to put together a plan for the private business of the stadium to prospect the middle of this year, it can not be showing the detailed drawings of the stadium to private contractors for reasons of security of the Tokyo tournament Because of this, it is postponed after the tournament.
