Japanese artist Michiari Saito builds treehouses with the citizens of Kesenuma, one of the towns that were severly affected by the 2011 tsunami that caused the Fukushima disaster as well. A protective barrier now separates the twon from the sea. The view out of these treehouses allows different perspectives on the twon and the landscape, for example seeing the waterfront without the massive wall. The treehouses thus are a sort of time machine as well as an effort in community healing. (The video is japanese with German subtitles only)
