I was just remembering Nakagin when I was translating my old paper into Japanese. I happened to be walking in Ginza and it was destroyed, I don't think it's a frame problem in the popular sense, but simply an ownership question I felt it at the time of Shinsaibashi, but I think it would be better to sum it up, and I think we need experts who are not architects.

昔の自分の論文日本語訳しててちょうど思い出してましたナカギン。たまたま銀座歩いてたら壊されていました、俗にいうフレーム問題ではなく、単にオーナーシップの問題だと思います。心斎橋の時も感じましたけど、総括したほうが良いのではないでしょうか、建築家ではない専門家が必要と思います。
