This piece of architecture was not favoured by most of leading architects and also most of the audience not just in japan but worldwide.
I personally think this does not consider any context what so ever and with just bad design of spaceship or helmet.
This may work in China...like there is no context and she can build whatever she wants.
This attitude does not work in Japan...
Her statement does not stand very well after all this is a piece of bad design....not great architectural design.
The current stadium is such a great piece of art and architecture...I am quite surprised as to why the Japanese prime minister try to utilise it.
