Kenzo Tange's Masterpieces, the Tokyo Olympic Stadium, easily more beautiful than any of the other Olympic Stadiums, closest counterpart I can think of is the one for Athens by Calatrava.
The tour was conducted last week, JUST LAST WEEK. Theres nothing much really to expect from a forest, the forest that it is, but its nice to know that something is actually happening within that desolate site. and the substation is such an errie sight, i wonder why they left it.
